The Penn Medicine Department of Surgery dates back to 1765, when Penn’s medical school was founded. Since then, it has been recognized for extraordinary contributions to surgery and surgical research, including many American surgery “firsts.” Today, the department’s standing and associated faculty operate at 10 sites and see outpatients at nine locations in southeastern Pennsylvania and southern New Jersey.. The continuing generosity of Penn’s benefactors has provided the department with one of the largest endowments for research in the country.
