Our Approach

If you’ve registered for a COVID-19 vaccine online, dose #1 and dose #2 have been reserved for you at the time of your scheduled appointment.

In November 2016, CHRISTUS Trinity Mother Frances Herrington-Ornelas HealthPark opened offering a wide range of healthcare services to the residents of Whitehouse and southeast Tyler.

With our staff of family medicine physicians, family nurse practitioners, physician assistants and our visiting specialists, we are able to provide comprehensive care for your entire family.

Our distinguished providers are dedicated to efficiently meeting the healthcare needs of the patients we serve with compassionate, quality care. Our providers seamlessly coordinate every aspect of your care to assure the best outcomes. Our clinic offers a collection of services including:

Universal Masking

We at CHRISTUS Health value your health and safety. Consistent with recommendations from the CDC and the Texas Medical Board, we are requiring all patients, visitors and employees to wear a mask while within our facilities. Masks are not advised for children under age 2. Please bring your mask from home with you to your appointment. Any double layered cloth mask covering your nose and mouth is appropriate for visiting our clinics as long as it does not have an exhalation valve. If you cannot come alone to your appointment, please bring no more than 1 essential visitor with you.

If you are ill with fever and cough or shortness of breath, please contact your clinician's office for instructions before coming into the clinic. You can streamline your check-in process and help maintain social distancing by using the e-Check in feature in MyChart prior to your arrival. We appreciate the opportunity to serve you. These measures are just a few steps we are taking to ensure to provide you and all others a safe environment.
