The United Network for Organ Sharing (UNOS) has announced the appointment of Andrew S. Klein, M.D., M.B.A., F.A.C.S., as its new Chief Medical Officer. Dr. Klein, who is widely regarded as one of the most respected transplant surgeons and clinical researchers in the United States, brings over three decades of experience in clinical transplantation to his new role.
According to UNOS CEO Maureen McBride, Dr. Klein will serve as an expert medical and clinical resource for UNOS staff, the organ donation and transplant community, and the general public. His responsibilities will include assisting with research projects and publications, as well as providing medical and clinical perspectives on UNOS corporate initiatives.
“During his 35 years in clinical transplantation, Dr. Klein led transformational culture change and leads with an emphasis on inclusivity, engagement, transparency, and communication – the type of leadership the organ donation and transplant community needs during this time of modernization of the nation’s transplant system. Dr. Klein’s expertise will support UNOS’ continued growth as a global leader in donation, transplant, and health,” McBride stated.
Dr. Klein was the founding Director of the Johns Hopkins Comprehensive Transplant Center from 1996 to 2003 and of Cedars-Sinai Comprehensive Transplant Center from 2004 to 2022. His extensive list of honors includes the Clinician Scientist and Distinguished Alumnus awards from The Johns Hopkins University, the Healthcare Visionary Award from the American Liver Foundation, and induction into the Johns Hopkins Society of Scholars.

Dr. Klein's academic credentials are equally impressive. He received his undergraduate degree from Duke University and his M.D. and M.B.A. degrees from The Johns Hopkins University. He also completed fellowships at Harvard University and the David Geffen School of Medicine at UCLA.
