Meet The Faculty

Faculty from the Abdominal Transplant Fellowship at Mayo Clinic in Minnesota work on a clinical case.

The Division of Transplant Surgery at Mayo Clinic in Arizona is an integrated, collaborative, and high-functioning group of transplant surgeons from around the world. All surgeons perform liver, kidney, and pancreas transplantation. In the group, there are seven transplant surgeons, and eight physician assistants and nurse practitioners, and value close working relationships with each other and our counterparts in hepatology, nephrology, cardiology, and others in the Transplant Center and Mayo Clinic Hospital.  

Faculty

Members of the Division of Transplant Surgery at Mayo Clinic in Arizona are national leaders in the field of transplantation. They play important roles locally in the Transplant Center and the Department of Surgery, serve on Mayo Clinic administrative committees, and conduct federally-funded clinical and health services research, as well as serve in national administrative roles in the field of transplantation, and teach postgraduate and continuing education programs.

The faculty members have published and lectured extensively and are well-regarded in their fields. You will develop a close relationship with these faculty members during your two-year training program and beyond.

From the program director

Jack Harbell, M.D.Transplant surgery at Mayo Clinic in Phoenix, Arizona, has a rich history. Over the last decade, we have rapidly transformed into one of the largest transplant centers in the United States, embedded in one of the country’s top hospitals. Our fellowship training program is a comprehensive two-year experience, aimed at providing fellows with the best in modern transplant training. The clinical program ranks among the best in the U.S. in transplant outcomes in all organ groups, based on recent SRTR reports.

We emphasize clinical and technical excellence. The program is certified by the Transplant Accreditation and Certification Council and the American Society of Transplant Surgeons in liver, kidney, and pancreas transplantation. There is also substantial exposure to hepatobiliary and pancreas surgery.

In addition to clinical excellence, the opportunities for participation in research, education, and quality improvement are numerous. You typically present research at national meetings and publish articles in peer-reviewed journals. You develop as leaders by directing clinical transplant teams in conjunction with faculty and working with a rich cohort of advanced transplant providers and surgical residents.

An unusual feature of our program is the opportunity for external rotations at other Mayo Clinic sites, which exposes you to other transplant environments as they prepare for a career in this amazing field.

Living in the Phoenix/Scottsdale metropolitan area also provides you with an amazingly beautiful and dynamic urban setting to serve both as a backdrop for your training and a welcome distraction during moments of freedom.

In short, I believe our program is one of the best transplant surgery fellowships in the country. Our fellows graduate more than adequately prepared to independently carry on Mayo Clinic's legacy of transplant excellence in clinical care, education, and research in their careers.
