Our Approach

At CHRISTUS Weight Loss Institute you'll find a program designed to help you lose weight with the education and support you need for long-term success. We go far beyond surgery to provide a life-changing program that includes nutritional guidance, support groups, and coordination of counseling services.

We believe in educating patients to make the lifestyle changes required for successful weight loss and we are committed to providing the support needed to lose the weight and keep it off. An important part of the CHRISTUS Weight Loss Institute-Westover Hills process is a psychological evaluation to help establish a clear understanding of the post-operative changes in behavior that are essential for long-term success.

Weight Loss Support Groups

The Weight Loss Institute offers weight loss support group monthly for our post surgical patients ( patients who have already had surgery) to network and maintain weight loss and healthy mental and physical well being. This is the first Thursday of each month at 6 pm.

Weight Loss Seminars

Dr. Richard Peterson and his partners lead seminars for prospective patients (patients who have not yet had surgery). These seminars are held the second Thursday of each month at 6 pm and the 4th Saturday of each month at 10 am.

Patient Story


I can tell you that having the gastric bypass was by far the best decision I ever made. I have lost 150 lbs and I feel absolutely wonderful. I never realized how bad I felt before and now that I feel so great I realize how bad it was.
