Our Center for Metabolic and Bariatric Surgery Team

Our team has performed thousands of weight loss surgeries and is supported by a professional staff of dietitians, physician assistants, and a psychologist who specialize in caring for the weight loss surgery patient. All of our surgeons are certified by the American Board of Surgery and are respected faculty members of Harvard Medical School.

Our surgeons perform weight loss surgery at both Brigham and Women's Hospital and Brigham and Women's Faulkner Hospital and appointments can be scheduled at both locations as well as our clinic in Weymouth at Brigham and Women's Surgical Associates South Shore.
