Leaders in Organ Offer Management

Our Team

Steve Pitzer

Steve Pitzer comes to Transplant Coordinators of America with nearly 25 years of experience in the organ donation field. He got his start in the field in 1986 as an organ procurement coordinator in the U.S. Air Force. From there, Pitzer was employed with UNOS Organ Center as an organ placement coordinator. He moved to South Carolina in 1993 to take a position as an organ procurement coordinator with the South Carolina Organ Procurement Agency — now known as LifePoint. He was promoted to director of organ recovery in 1998 and as the company grew, he became the vice president of organ recovery.

Robert Koppenaal

VP Operations

Robert began his journey in the transplant field over 13 years ago. He started with Transplant Coordinator of America 6 years ago and has since become a vital role in the development of our operations. His innovative mindset has allowed our organization to become the high-quality service experience your team has come to value and expect. Robert has long understood the transplant center’s need for expeditious accurate information, he was the first to post detailed bronchoscopy videos to Donornet, increasing lung transplants. As one of the first in the OPO field to develop an Advanced Practice Coordinator program, he recognizes the need for streamlining transplant processes. His obvious dedication and passion show in his everyday support of your Transplant Center and the coordinators dedicated to your transplant team.
