Under the leadership of Noel Williams, MD, FRCSI, director of the Metabolic and Bariatric Surgery Program, our staff consists of a team of professionals who are experts in their respective fields — nursing, nutrition, psychology and surgery. The team works together to provide patients with the best surgical care, while also helping patients achieve lifestyle and weight loss goals.

We're committed to helping patients achieve their weight loss goals and improve their overall health. Because every patient considering bariatric surgery is unique, our program offers a full range of bariatric surgical options, ensuring that patients receive the bariatric surgery that will provide them with the best possible results.

All procedures performed here use a minimally invasive approach called laparoscopic-assisted surgery, which offers many benefits for patients including shorter recovery times and less post-operative pain. 

MBSAQIP Accredited CenterThe Penn Metabolic and Bariatric Surgery Program is accredited a MBSAQIP Accredited Center – Comprehensive at all three of our locations: Hospital of the University of Pennsylvania, Pennsylvania Hospital and Penn Presbyterian Medical Center.
