Our program at Texas Health Hospital Rockwall is a full service bariatric or weight loss program that offers many options combined with long-term support. Our goal is to address the needs of patients of size who want help in finding their health again.

Many of our team members are bariatric patients themselves. They understand where you are because they have traveled the same road. They have dealt with the guilt and shame you might feel. That is NOT who you are! We can help you explore the options that might make sense for you and help you achieve your weight loss needs and goals.

You will not be alone in this journey, but rather will have the guidance, experience and support of a highly skilled resource team – your patient advocate, dietitian, nurse, and, of course, your physician. In addition, there are routine office visits, electronic and phone accountability communication, monthly support groups and fitness options offered to help you achieve your goals.
