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. 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.
