Thank you for your interest in the University of Colorado Transplant Surgery Fellowship Program. Congratulations on taking the next step to becoming a Transplant Surgeon!

The University of Colorado School of Medicine and the Division of Transplant Surgery are proud to provide a two-year Transplant Fellowship Program accredited by the American Society of Transplant Surgeons (ASTS). Our program is currently set up to train one fellow for two years.

The purpose of the fellowship is to expose and educate a qualified surgeon to the surgical techniques of solid-organ transplantation encompassing procurement and pre/post transplants.

Our program involves a multidisciplinary team approach dedicated to high-quality, patient-focused transplantation. Members of our team include transplant surgeons, hepatologists, nephrologists, anesthesiologists, pathologists, transplant nurses and coordinators, financial coordinators, transplant administrators, social workers, and other professionals who specialize in transplantation. This integrated approach ensures the highest level of care and has given us a competitive advantage improving our clinical outcomes.

Additionally, the Division of Transplant Surgery supports an academic research component. We continue our ongoing development and assessment in techniques with live-donor liver transplant. Since 1994, this program has successfully calibrated many surgeons in completing the two-year fellowship program.

In order to qualify for the University of Colorado Transplant Surgery Fellowship position, please take time to carefully read what is required.

The Fellow must:

  • Be a U.S. Citizen, lawful permanent resident, refugee, asylee, or possess the appropriate documentation to allow the Fellow to legally train at the University of Colorado School of Medicine.
