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.

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.

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.

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.

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.

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 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.
