Medical Team - Bariatric Surgeons & Staff
The Temple Bariatric Program uses a multidisciplinary approach that brings a wide variety of specialists together to help you achieve your weight loss goals. Not only do we have some of the finest bariatric surgeons in the region, but we provide a unique support system that will help you maintain your "new you" for a lifetime.
Our team of doctors and health professionals consists of surgeons (who perform gastric banding, gastric bypass, sleeve gastrectomy and duodenal switch surgeries), nurse practitioners, surgical assistants, registered dietitians, psychiatrists, nurses, case managers, home caregivers, and administrative assistants.
All Temple patients undergo thorough pre-operative testing and receive a private consultation with a Temple bariatric surgeon. After the tests are complete, our bariatric team meets with each patient to review his or her readiness for bariatric surgery. On the day of surgery, our surgeons meet with each patient prior to the procedure, talk to the family members after surgery, and monitor patients closely while they are hospitalized. All of our patients are carefully followed post-operatively at regular intervals during the first year, and at least annually thereafter.
Temple bariatric surgeons are board certified.

Temple dietitians analyze your current eating habits and help prepare you to make healthy food choices both before and after surgery. This is an important component for long-term success. Dietitians participate in the pre-operative educational classes and conduct an individual consultation with the patient, which all Temple patients attend before surgery. Patients are also seen by the dietitians in the hospital after surgery for post-operative educational reinforcement and encouragement.
