Dr. Clive O. Callender, Professor of Surgery at Howard University College of Medicine, is a trailblazer in the field of organ and tissue donation. Since 1973, he has led transformative initiatives, including developing the first minority-directed dialysis and transplant center in the U.S.
In 1991, Dr. Callender founded the National Minority Organ/Tissue Transplant Education Program (MOTTEP), the first organization to combine disease prevention with increasing organ donation rates. Under his leadership, minority donation rates rose from 15% in 1990 to 30% in 2008, with Black donor rates exceeding other populations by 2018.
