First Year Residents 

Joshua Kuehne, DOJoshua Kuehne, DO

Hello there! I was raised in the rural central Texas town of Lampasas. I moved to San Antonio in 2012 to complete my undergraduate degree at the University of Texas at San Antonio in kinesiology with a focus in athletic medicine. I went on to attend medical school at UIW School of Osteopathic Medicine here as well. Initially, however, I went to college with the intention of becoming an architect and civil engineer! Following my first year, I was in a near-fatal car accident that put me in the hospital for a month and several months of physical and cognitive outpatient rehabilitation. The entire experience was quite intriguing and taught me how much adversity the human body can overcome with the aid of love, support, and medicine. I little bit about myself, I love learning from nearly all subjects from astrophysics to art history, I am an avid dungeon and dragon player, and most of all I enjoy spending time and traveling with my wife and son.

I chose family medicine because I loved all my rotations and going into primary care would allow me to practice full spectrum care. Moreover, I’ve found that in primary care I’ll have the unique privilege and honor to empower patients with my story so they too can improve their health and wellness, and overcome significant illness. I chose CHRISTUS Santa Rosa because of the passion faculty, supportive culture amongst the residents, opportunity to gain a wide breadth of experience, and because of San Antonio. In the past decade of living here, I discovered my calling in medicine, met my beautiful wife, started a family, and ultimately was given a second chance at life. My family and I are hoping to stay here long after residency to take care of the community that has given so much to us.  

Richa Patel, DO

Hello and Welcome! I was born in Gujarat, India and moved to Colorado, USA when I was 11 years old. Texas is my second home as I completed my undergraduate studies in biomedical engineering from Texas A&M University in College Station, and medical school from UIW School of Osteopathic Medicine in San Antonio. I am fond of Family Medicine because I enjoy interacting with diverse patient populations from all age groups with different medical histories. My goal for choosing CHRISTUS Santa Rosa for my residency is to build on a strong knowledge base, improve my hands-on skills, connect with amazing mentors, and grow along with my peers in an unopposed program.

On a lighter note, I love living in San Antonio as it gives me the ability to enjoy multiple outdoor activities with family and friends. I like to do yoga and HIIT combination exercises daily to relax. On a weekly basis, I play basketball and/or volleyball with friends. I also draw and/or paint realistic images while listening to Bollywood music for fun. Thank you for taking the time to get to know me!

Liya Thomas, DO

Hey y’all! It’s a pleasure to share a little bit about myself with you. I was born and brought up in a small state in India called Kerala. After moving to the U.S. at the age of 7 with my parents and brother, life was full of changes and new places including cities in New Jersey and Texas. My family settled down in Allen, TX during my eighth grade and have called the DFW area home since then. I completed my undergraduate degree in Psychology and Public Health at Austin College in Sherman, Texas. It was during those years that I gained a deep desire to pursue a career in medicine, with interests in medical missions, public health, and community outreach. I was fortunate to travel to various places for medical missions and public health study abroad trips, including Haiti, Cambodia, and Ghana. I also got to be a part of many community outreach events and shadowing opportunities. These experiences shaped my outlook on the necessity of primary care and the importance of the phrase ‘prevention is better than cure’. They also broadened my perspective on how impactful a primary care physician can be in the health of an individual, especially with a trusting and open doctor-patient relationship.

I attended medical school at Lincoln Memorial University, DeBusk College of Osteopathic Medicine. I was able to meet wonderful friends and mentors that encouraged, taught, and guided me through those years in didactics and clinical rotations. These years solidified my passion for family medicine and advocacy in primary care. It was also during this time that I got to know and get married to my husband, the best thing that has happened to me!

During my free time, I love to spend time with my husband, family and friends, cook, go on walks, try different cuisines, enjoy nature and travel.

I am so grateful to join the CHRISTUS family where I’m confident I will get the foundation I need to be a well-rounded and patient-centered family physician. This program has all the attributes I was looking for in a residency, including a full spectrum, unopposed family medicine residency experience, an emphasis on continued education and a close knit community. Although residency is bound to be a challenging time, the people at this program have shown that it can also be a great learning experience with the right community by your side to support and encourage you through it.

Dylan Salazar, MD

Hi everyone! My name is Dylan and I am from Leming, TX! I majored in Biology at the University of the Incarnate Word for undergrad and attended Texas Tech University Health Sciences Center El Paso – Paul L. Foster School of Medicine for medical school. I chose Family Medicine because I really enjoyed each of my rotations throughout medical school and really appreciated the broad scope of practice and wide variety of career opportunities that FM has to offer! I am excited to begin my training with the CHRISTUS Santa Rosa Family Medicine Residency Program as they offer full-scope, unopposed training and have a supportive, family-oriented environment!

Kaleb Starr, DO

Hello friends! I was born and raised in Tampa, Florida. I completed my undergraduate education at Florida State University, where I also met my beautiful wife. After two years of working as a psychiatric technician, I moved to San Antonio to attend medical school at the UIW School of Osteopathic Medicine. I've wanted to be a physician since I was a little kid, so this is the realization of a lifelong dream. Since my time at Florida State, my interest has been in primary care and preventative medicine. I wanted to work in a field that allowed me to flex to the needs of my community. I like kids, I like adults, I like our more well-seasoned folks. I enjoy seeing a wide variety of health concerns. This all made family medicine a natural fit. I was lucky enough to rotate at CHRISTUS Santa Rosa several times as a medical student, and each time I was treated like family. I got to see firsthand the relationship that residents have with faculty, how compassionate everyone is at the program, and how top-notch the training is. Making CHRISTUS Santa Rosa my top choice was an easy decision.

In my free time I enjoy living an active lifestyle with my wife and my two dogs, Jameson and Ginger. I'm an avid long-distance runner and a painfully average crossfitter. On long weekends I enjoy backpacking and hiking in some of our great state and national parks. I'm a loyally devoted fan of the Tampa Bay Buccaneers (Fire those cannons), Tampa Bay Lightning, Florida State Seminoles, and the Houston Rockets.

Claire Yoon, MD

Hello! Although not originally from here, I am a true San Antonian at heart, and this city is like home to me. I kicked off my journey at UT Austin for my undergrad, but I couldn't wait to come back home for medical school at UT Health San Antonio. Family is everything to me, so I spend most of my time hanging out with my siblings and parents. I met my husband, who's also a native San Antonian, during our first year of medical school, and we are very excited to start our own family soon! The family vibe at CHRISTUS is what really attracted me to the program. I was drawn to a program where I felt supported not just in my professional life, but also in my personal journey. Being able to care for patients based on a value system that aligns with my own is a dream come true. I can't wait to dive headfirst into holistic patient care and create some incredible memories with my fellow interns. In my free time I am usually hanging out with my husband and dog, exploring new places, or getting lost in a good book.

Matthew Mastrodicasa, MD

Hello! I was born in New York but was raised in Austin TX. I was lucky enough to attend the University of Texas at Austin where I graduated with a BSA in Neuroscience. Then I continued my journey into science by attending medical school, here in San Antonio, at the University of Texas Health Science Center San Antonio Long School of Medicine. I decided to pursue a career in family medicine because of the variety of care family medicine doctors are able to perform and the opportunity to build long-lasting relationships with my patients. CHRISTUS Santa Rosa is a great fit for my career goals due to the full-spectrum “unopposed” training that we receive, allowing me to develop a solid foundation to grow as a physician moving forward. In my free time I love to bake, play board games, travel and try tasty foods from all over the world, and I recently found a love for gardening.

Margaret McNew, MD

I was born and raised in Shreveport, Louisiana. I completed my Bachelor of Science in Biological Sciences at Louisiana Tech University in 2019 and then graduated from medical school at LSU Health Shreveport School of Medicine in 2023. My husband is a pilot in the US Air Force, and we enjoy being active outdoors and never turn down a new adventure! We have two cats, Luna and Nugget, and are about to adopt a dog as the newest addition to our family. I enjoy being involved in my local church, trying new foods, weight-lifting, and binging a good TV show.

I chose Family Medicine as my specialty because I value establishing life-long relationships and making genuine connections with my patients. I’m passionate about educating patients on their medical diagnoses, improving their health literacy, and maternal-child obstetrics care. CHRISTUS Santa Rosa was my first choice for residency because it is a full-scope family medicine program that offers extensive training in procedures, OB deliveries and surgical training, and a welcoming friendly work environment! Each resident is encouraged to tailor their experience according to their career interests.

David Fuhriman, MDDavid Fuhriman, MD

Hi all! I am a transplant to Texas from California. Now, before you all judge me too harshly, I will say that the first 5 years of my life were spent in Austin and Missouri City, TX. So I guess you could say I am just coming back to my roots! Growing up in the San Francisco Bay Area, I developed a love for all things outdoors, including beach trips, hiking, backpacking/camping, trail running, lake sports, and winter sports. Additionally, I developed a strong interest in biology and physiology. Those studies, combined with a passion for helping people, sparked an interest in medicine. I completed my undergraduate degree in Microbiology at Brigham Young University and was heavily involved in bacteriophage research. As I worked with my research mentor, I met my wife, Morgan (a story for another time!) and then we moved to Houston so I could attend McGovern Medical School. During medical school, my wife and I had two children, Nick and Jenny, and they make us laugh every day. Throughout medical school I also gained an appreciation for the scope of medicine that a family physician can pursue. I was drawn to CHRISTUS Health because of its strong emphasis on holistic patient care and the exceptional training opportunities in a great family-friendly city. I also look forward to practicing my Spanish every day! My particular interests include sports medicine, addiction medicine, global health, and geriatrics, and I am excited to see how those passions evolve throughout my residency training here at CHRISTUS Health!

Kalli Glass, DO

My name is Kalli Glass and I’m from Gonzales, Texas. I am married to my wonderful husband Kameron, and we have one child, Kace. We enjoy living in our small hometown and my goal is to return to Gonzales after residency to practice full spectrum rural family medicine.

I completed my undergrad in biology at the University of the Incarnate Word in San Antonio where I also went on to receive a Master of Arts in biology. I attended medical school at the University of the Incarnate Word School of Osteopathic Medicine in San Antonio and after 8 years of school in San Antonio I now consider it my second home. For this reason, I am so excited to be completing my residency at CHRISTUS Santa Rosa Westover Hills in San Antonio! I am confident this program will help prepare me to be a well-rounded family medicine physician with all the necessary skills to practice in a rural setting.

Second Year Residents 

Sergio Aleman MDSergio Aleman, MD

Hello there! I was born and raised in San Antonio as the oldest of four siblings. I enjoy watching sports (big Spurs and Barcelona fan) and spending time with my wife and family. I went to undergrad at the University of Texas at Austin where I studied sociology and biology. Some of my favorite experiences during my time at UT was to study abroad in England and to perform with the UT Mariachi. Eventually, I was fortunate to attend medical school in my hometown at UT Health San Antonio. I have always been interested in family medicine throughout my education due to my own personal experiences that led me to want to be a family doctor myself. I am glad to be part of a supportive program and to be able to complete my training so close to home.

Cara Anderson MDCara Anderson, MD

Hey y’all! I am from Carrollton, Texas. I started undergrad at Pepperdine University and then transferred to the University of Texas at Austin (Hook 'em, Horns!) where I graduated with my bachelor’s degree. I went to UTMB in Galveston, Texas for medical school and am super excited to be back in the Texas Hill Country in San Antonio for residency! Things I love include all types of music, trying out different coffee shops and breweries, and my sweet pup, Ladybird.

I chose CHRISTUS first and foremost because of the family-feel of the program. The residents, faculty, and coordinators are so welcoming and clearly demonstrate how much they love working together and hanging out outside of work. I also chose CHRISTUS for the complexity of training we get here in a community setting between managing ICU patients, delivering babies, working at the children's hospital, and more. There are endless opportunities for learning here! I'm honored to be working alongside amazingly personable and intelligent residents and attendings.

Oscar Gonzalez MDOscar Gonzalez, MD

I am from the Mid Cities area near Fort Worth, TX. I have graduate research training in molecular radiation biology and used to teach basic sciences as an adjunct instructor in community colleges and medical assisting programs. I decided to change careers and pursue a career in medicine to continue my learning, apply my knowledge of basic science, and use my skills in teaching and communication to help my community.

I chose family medicine because it was the field of medicine most integrated in my life. From my geriatric parents, to my personal problems with my creaky knees, to my pediatric grandchildren, family medicine is connected to every aspect of my life. I chose CHRISTUS Santa Rosa because I found it to be the most welcoming and supportive residency program I could find.

Sabina N Lalani DOSabina Lalani, DO

Hi y’all, thank you for taking a minute to get to know me! I grew up in Sugar Land, TX and my family is from Burma, Bangladesh and Pakistan. I went to undergrad at Trinity University in San Antonio and studied abroad in London. I took a gap year before medical school and completed a Master of Arts in Medical Sciences at Loyola University Chicago. Right before I started at UIW School of Osteopathic Medicine in San Antonio, I did an internship in Hydrabad, India which further solidified my passion for working in underserved communities. I was drawn to Family Medicine because I loved all my core rotations and enjoy diversity in my day. I have a passion for women’s health, enjoy seeing pediatric patients, and really like building connections with my patients in the clinic. I ranked CHRISTUS Santa Rosa as my top choice because during my 4th year audition rotation I was able to see the amazing learning opportunities the residents at CHRISTUS had access to daily. I wanted to go to an unopposed program that provided me a solid foundation to grow as a physician and one that had a supportive family environment.

Finally, I wanted to share a little bit about myself. If it was not apparent from above, I love to travel and explore cultures and foods from around the globe! I enjoy playing basketball and volleyball, as well as hosting game nights for my family and friends. My fiancé and I recently got a corgi so lately we have enjoyed spending time outdoors and teaching her new tricks.

Eloy Martinez, DO

I was born and raised in the small, South Texas border town of Zapata. I completed my Bachelors of Science in Biology at Texas A&M International University in 2017. I then moved to San Antonio to pursue both my Masters in Biomedical Sciences and Doctor of Osteopathic Medicine at the University of the Incarnate Word School of Osteopathic Medicine.

I chose a career in medicine after recognizing, both personally and through loved ones, the healthcare disparities that impact rural minority populations. I then pursued family medicine specifically given my passion for preventative care and appreciation for the versatility that this specialty provides professionally and clinically. I am currently considering pursuing a sports medicine fellowship to provide care in the future to my home community and local public school athletes. I chose CHRISTUS for its supportive and collaborative culture, the passion for teaching displayed by its residency faculty, and the flexibility of the program to tailor each residents training to complement their future career aspirations.

Bethany Pierce, MD

I was born in San Antonio but raised in a small town called Monett in Missouri. I moved back to Texas as a teenager and went to high school in College Station, college at TCU in Fort Worth, and medical school at UT Health in San Antonio. I chose Family Medicine because I value connecting with and caring for patients, and this field provides continuity of care, a broad scope of practice, and a wide variety of career options to make that possible. I chose CHRISTUS because of the people, the community-based environment, and the opportunity to learn a diverse set of skills as a family medicine doctor in numerous healthcare settings.

Sara Stubbs-Walden, MD

Hi there! I was born and raised in the Rio Grande Valley, a wonderful place in the southernmost tip of Texas. I completed my undergraduate studies at the University of Texas Rio Grande Valley where I majored in Biology. I was part of an early medical school acceptance program that granted me conditional acceptance to the University of Texas Medical Branch when I was 18! Thankfully, I was able to complete the program and I successfully matriculated to UTMB following my college graduation. I moved to Galveston and lived the island life for medical school. I made life-long friends during my time there and I was fortunate enough that they all moved to San Antonio for residency! I also met my husband (and fellow intern), David at the end of our first year of school. We got married right in the middle of interview season and amidst a COVID surge, but it was truly a magical day. I chose a career in Family Medicine because I believe that family physicians can have such a positive influence in the lives of patients. I genuinely enjoy making connections with people. Talking to and learning about the people I care for is incredibly important to me. I am also passionate about educating patients on their chronic conditions and advancing their health literacy. I chose CHRISTUS for my residency for several reasons. They offered me all the training opportunities I wanted as a full scope, unopposed, community program. They also made me and my husband feel so welcomed and cared for during the interview process. I truly felt that I would fit in perfectly at this program and this community. I am so excited to learn and grow here at CHRISTUS, and I can already tell that I am surrounded by some pretty amazing people!

Jordan Ta DOJordan Ta, DO

Hello friends! It’s a pleasure to meet you! My name is Jordan and I was born and raised in Fort Worth, Texas. I completed my undergraduate education at Texas Tech University in Lubbock, Texas. I attended medical school at UIW School of Osteopathic Medicine here in San Antonio. I am blessed with a wonderful wife and a sweet baby girl. Fun facts: I love music and playing guitar, I have a passion for cooking, and my wife and I are the biggest foodies you will meet! Since starting our journey in San Antonio, we have enjoyed trying and discovering the diverse culture and cuisines this city has to offer!

I chose family medicine because I wanted to be well-equipped to treat patients of all ages and of all different conditions. In addition, I found that primary care physicians have the unique opportunity to develop long-term relationships with their patients. I love being a resident at CHRISTUS Santa Rosa because of the unopposed full-spectrum training it offers and the family-like environment of all the residents and staff. I am confident that my training here will help me to succeed in pursuing any career in family medicine.

David Walden MDDavid Walden, MD

I was born and raised in a small town, 30 minutes south of Dallas. I went to Oklahoma Christian University, where I studied biology and played the bassoon. I followed my brother in going to the University of Texas Medical Branch for medical school, where I fostered interests in mindfulness and evidence-based medicine; starting my own journal club newsletter. I enjoy listening to podcasts, playing games, watching movies, and spending time with my wife and 2 cats, Loki and Kiki.

Taylor Works MDTaylor Works, MD

Hello! I was born and raised in the Westlake area of Austin, where I was fortunate to get an early start with my love of the sciences. It was during those early days that I also met my wife, Lorraine, whom I’ve known since the 6th grade and has been my greatest supporter along this exciting journey. My early inspiration to pursue a career in medicine came from the legacy of my grandfather, who was a beloved physician that left a lasting impact on the people of Brownsville, Texas, where he lived and practiced for many years. After high school, I moved to College Station to attend Texas A&M University, where I received my Bachelor of Science in biology and got more exposure to the medical field through opportunities like cancer research, clinical volunteering, and working as a phlebotomist. It was these experiences that solidified my passion for medicine and I went on to join the Long School of Medicine class of 2022 at the UT Health Science Center here in San Antonio. I found my love of Family Medicine during my 3rd year rotations when I saw the immense need for high quality primary care and the endless practice and career opportunities that come with it. In my free time, I enjoy cooking, outdoor activities like fishing and hiking, and finding new and exciting activities and restaurants around San Antonio with my wife.

I am so grateful for the opportunity to join the class of 2025 at the CHRISTUS Santa Rosa Family Medicine Residency, which was my first choice. CHRISTUS is the perfect program for me because I want to be challenged with vigorous full-scope, unopposed training that will truly prepare me to practice in any environment. From my first interaction with the program, I could feel the supportive family-oriented atmosphere that many residencies claim to have but only few truly possess. I’m excited to learn from our faculty, who are heavily invested in our professional development, and lucky to have the opportunity to continue caring for the patient population of San Antonio that I have come to know and love.

Third Year Residents 

A headshot of Sandra GeorgeSandra George DO, PA-C, RD, LD

I grew up all over the US but consider San Antonio home. I attended UT Austin for undergrad, then went to Albany Medical College for PA school and lastly went to Lake Erie College of Osteopathic Medicine for medical school.

I look forward to a servant mentality encompassed by the Christus network in the practice of medicine and in treating patients.

I don’t have any one single hobby (wish I did!) but enjoy hanging out with family, friends, traveling (been to more about 20 countries and counting!), eating, working out and baking. These are some of my favorite things. But always open to trying more things out like skydiving and what not!

Timothy Hover, DO

Hey y’all—yes, I’m a true Texan—born and raised here in San Antonio. I was a non-traditional medical student, with a near three-year gap between my undergrad completion at the University of the Incarnate Word (UIW) and starting medical school as a member of UIW’s inaugural class. During my gap years, I began working with H-E-B pharmacy, which continued into the early part of my second year of medical school.

I am an avid NBA and NFL fan. My favorite teams are the San Antonio Spurs and the Minnesota Vikings, respectively. I also dabble in a bit of Fantasy Football. I have two rescue dogs named Kiwi and Brownie. Kiwi is a Golden Retriever, and Brownie is part retriever and part sneaky neighborhood dog.

I ranked Christus Santa Rosa as my top choice for three reasons. First, Christus is an excellent learning and teaching hospital, and being an unopposed program is a bonus. Second, the program has a solid supportive family feel, which I noticed during my interactions with residents at local TAFP chapter meetings. Lastly, I have an emotional connection because my grandmother worked for the original Santa Rosa Hospital as a housekeeper for 19 years before retiring. Although my grandmother is no longer with me physically, being a part of the Christus family only strengthens our shared bond.

My near-term goals include learning and applying as much medical knowledge as possible while being a supportive and helpful teammate. Ultimately, I want to remain in San Antonio because there is such a tremendous opportunity to help care for, educate, and empower the growing population base into taking a more active role in their personal health.

Stephen Kamucheka, MD

My interest in medicine dates to my childhood in Harare, Zimbabwe. My mother was a long-time nurse and midwife, and I had the opportunity to watch her work with her patients every time that I visited her at her workplace at a tender age. She also kept numerous medicine textbooks in our modest bookshelf at home and I thoroughly enjoyed flipping through the pages and reading about the various medical conditions I came across. As I progressed through school, it became clear to me that science was my passion and that I wanted to pursue a career in healthcare. After moving to the US, I attended the University of Texas at San Antonio where I earned a bachelor’s degree in Biology followed by enrollment at the University of Texas Medical Branch at Galveston where I completed my medical degree.

At CHRISTUS Santa Rosa, I look forward to learning from faculty that are dedicated to the professional growth, development, and success of their residents. The diverse patient population I will care for will also offer unlimited learning opportunities. I also look forward to some of the long-term patient-physician relationships that I will form as I work with a diverse patient population.

Outside of the clinic/hospital, I enjoy playing or watching tennis, soccer, or going fishing or on a bike ride.

A headshot of Krystal KwongKrystal Kwong, DO

I was born and raised in none other than Sugar Land, Texas. I grew up as the middle child with two other sisters. I attended Houston Baptist University (Dogs Up!) and chased my love for science by graduating with a degree in biochemistry and molecular biology in 2016. One year later, I was delighted to receive an acceptance letter to the brand new University of the Incarnate Word School of Osteopathic Medicine. With the love, support, and encouragement from family and loved ones, I was able to finally earn my degree in osteopathic medicine in May 2021.

I cannot wait to build meaningful relationships with my patients and lifelong friendships with my co-interns and co-residents! I am looking forward to the upcoming challenges and many sweet memories that will be made in the next coming years. I hope to add to the positive and encouraging environment at CHRISTUS Santa Rosa. I am so excited and honored to be a part of the family!

I love trying new restaurants, especially brunch spots! Some of my favorite things to do when I have free time include getting my sweat on at the gym, dancing to hip hop music, throwing it down in the kitchen, and carpool karaoke with throwback/pop songs. On the weekends, I appreciate a slow morning getting ready before getting some Vitamin D in (with sunscreen, of course!).

Alyson Kohler, DO

Hi and thanks for considering the CHRISTUS Santa Rosa Family Medicine Residency! I took a circuitous route to get here, but I know I am where I am meant to be. I am originally from rural Pennsylvania, the closest well-known town near my hometown being Gettysburg. I attended undergraduate education at University of Pittsburgh, at one of their smaller branch campuses. I entered the healthcare field as a Medical Service Corps Officer in the U.S. Army, a position in which I served for seven years at every major Army post in Texas. I then decided I wanted to be more involved in the frontlines of healthcare and more directly impact patient health, leading me to the University of the Incarnate Word School of Osteopathic Medicine, here in San Antonio. I enjoy and plan to continue to incorporate osteopathic principles and practice into my patient care.

I met and worked with several of the family medicine residents over the course of third and fourth-year clinical rotations. I was incredibly impressed with their depth of knowledge and ease with patient interactions, often confusing them with the specialty residents also on the rotation service. I am so excited to be learning in this full-spectrum, unopposed program in which I can tailor my education to the style of family medicine physician I hope to become. Growing up in a rural town where the family physicians did everything from deliveries to hospital medicine, I know I will be able to emulate them after completing this residency program!

Outside of medicine, I enjoy going on spontaneous adventures and seeing new places with my family of three kids, a dog, and two cats. I love trying new food and wine, experiencing other cultures, painting either oil or acrylic on canvas, and trying new physical activities. My all-time favorite sport is volleyball, so I am always up for a pick-up game! Golf, tennis, and basketball are close seconds. Self-care is very important to me, and I try to incorporate meditation, relaxation, and being immersed in nature into my life as much as possible.

Hi! I was born in Oklahoma, however, grew up in Brownsville, Texas. I attended The University of Texas Rio Grande Valley and graduated with a BS in Biomedical Science. I attended medical school at The University of Texas-Medical Branch (UTMB). I decided to specialize in Family Medicine because I wanted to have continuity with my patients.

CHRISTUS was a perfect match for me because I would be exposed to full-scope family practice while being surrounded by amazing people. I always loved to visit San Antonio and now I get to enjoy the city for the next 3 years.

A headshot of Zachary SumnerZachary Sumner, MD

I grew up in Frisco, TX, a not so small town in north Texas. I went to Texas Tech University where I met my wife and got a degree in microbiology. We then moved back to North Texas where I got my medical degree from the Texas College of Osteopathic Medicine.

I am very excited to be at CHRISTUS. As a family medicine doctor I wanted to be able to care for my patients at all times during their lives and CHRSTUS is a great place to learn.

In my free time I like to travel different places with my wife and hang out with our dog Avery.

I love spending time with my dog Pepino, playing video games, binge-watching shows on Netflix and exploring new restaurants.

A headshot of Nicole WellmanNicole Wellman, DO

I am originally from San Antonio and am happy to call it home. I graduated from Churchill High School (Go Chargers!) and then went to college at St. Edward’s University in Austin. I continued to live there for a couple of years and worked as a medical assistant before coming back to San Antonio to attend medical school at University of the Incarnate Word.

I am excited to join the CHRISTUS family and provide patient centered care to serve people in the city that I grew up in. I am passionate about women’s health and preventive medicine. I am looking forward to giving back to the community that gave me so much.

In my free time I enjoy hiking and spending time outdoors with my two dogs, Lily and Sosa. I also attend trivia pretty regularly and even win on occasion!
