Dr. David Geller is the Richard L. Simmons Professor of Surgery at the University of Pittsburgh School of Medicine, and co-director of the UPMC Liver Cancer Center. As a hepatobiliary Surgical Oncologist, his clinical interests center on the evaluation and management of patients with liver cancer. He has pioneered laparoscopic liver resections, and has performed more than 300 of these cases. Most of these patients are discharged home on the second post-operative day with four to five band-aid-sized incisions. He also specializes in performing laparoscopic radiofrequency ablations of liver tumors. Dr. Geller is a member of many professional and scientific societies including the American Surgical Association, Society of Surgical Oncology, Society of University Surgeons (Past President 2010), and the American Society of Transplant Surgeons.
