About Us

We are a team of highly trained professionals who understand that weight loss can be a delicate topic and sometimes can feel unattainable. However, we understand that each patient is unique so we work with our team of specialists to provide a comprehensive approach to a weight loss plan that is right for each individual. Our team is dedicated to caring for each patient with every aspect of their weight loss journey.

The Comprehensive Center for Weight Loss offers a wide variety of weight loss options, both surgical and non-surgical treatment plans to include: laparoscopic gastric bypass, sleeve gastrectomy, duodenal switch, gastric balloon, gastric banding, and other minimally-invasive procedures. The operations performed by our specialized physicians are safe, the outcomes reliable, and most importantly, the health and lives of our patients are vastly improved.

Our highly trained bariatric surgeons have truly changed the lives of their patients through their commitment to helping them achieve their weight loss goals. They have witnessed remarkable surgical outcomes such as: diabetes cured, high blood pressure resolved, and obstructive sleep apnea gone. Patients, who once struggled to walk down the block, are running half marathons. Parents and grandparents, who once faced difficulties playing with their children and grandchildren, have vastly improved lives from bariatric surgery. Now these same parents and grandparents are able to walk, run, and play with their families. If you are considering entering into a weight loss program to better your health & lifestyle, don’t wait!

“What I like most about being a bariatric surgeon is the ability to change people's life in a dramatic and meaningful way. Bariatric surgery allows people to be more active and participate with their family in ways they couldn't prior to weight loss.” –Dr. David Thomas
