Weight Loss Surgery Program

Why Bariatric Surgery?

If you are someone for whom non-surgical treatments have failed to provide sustained weight loss, you can be evaluated for, and if appropriate, undergo lifesaving bariatric surgery. In cases of severe obesity, bariatric (weight loss) surgery is the only proven method of achieving long-term weight control. Our multidisciplinary team of bariatric experts will see you through the entire process. We will make certain that you are prepared for surgery, both physically and psychologically, and we will provide the most advanced and current procedures that are right for you. After surgery, we will assist you in committing to the lifestyle changes that will assure optimal success.
