Physicians & Teams
The multidisciplinary liver transplant team at Penn Medicine is comprised of specialists who manage patient care at every stage: from the evaluation visit through the transplant procedure and postoperative care. The program's goal is to provide the best care and restore each patient to a full and productive life.
