Benjamin Herdrich, MD, graduated from the University of Wisconsin in 2000, with a BS in molecular biology. He then attended the University of Wisconsin School of Medicine and Public Health, graduating in 2004. He completed his general surgery residency at the Hospital of the University of Pennsylvania including a two year research fellowship investigating fetal and chronic wound healing. He is currently a vascular surgery fellow at Penn.
