Our Program

Drexel Surgical Associates works closely with the Hahnemann University Hospital Center for Weight Loss Surgery, which was established in 2004 and consists of a multidisciplinary team whose members are located on the Drexel Med/Hahnemann University Hospital campus. We have performed hundreds of weight loss surgical procedures using minimally invasive (laparoscopic) surgical techniques.

Please feel free to call our offices at any time, at 215-762-4890.
