Waldo Concepcion, MD, FACS co-developed the Liver Transplant Program at California Pacific Medical Center from 1988-1994, at which time he and his team then moved the program to Stanford. In 1996 he was named Director of the Transplantation Institute at Loma Linda University Medical Center, founding the Pediatric Liver Program and serving as Surgeon and Chief over the Multi-Organ Transplant Program. Under his leadership, the program became a leading Transplant Center, reported as one of the highest patient and organ graft survival rates in Sothern California, and earned the Institution distinction of Centers of Excellence among Health Care Organizations. In 2005, he returned to Stanford as the new Chief of Pediatric Kidney Transplantation at Lucille Packard Children’s Hospital and continued the tradition of leading one of the best transplant programs in the world. In 2006, he was named Chief of Clinical Transplantation at Stanford University. Dr. Concepcion has published over 100 articles and book chapters in scientific literature.
