Dr. Marcus A. Conant

Chief Medical Officer

Dr. Conant was one of the first physicians to diagnose HIV in San Francisco while running the inpatient dermatology service at the University of California San Francisco. Before anyone recognized the virus or understood that it was about to become a global epidemic, Dr. Conant took the lead in forming the Kaposi’s Sarcoma Research & Education Foundation in 1982, which later became the San Francisco AIDS Foundation.


Dr. Conant conducted early clinical trials, persevering despite seeing 94% of patients die during the epidemic’s first years. His clinical experience sensitized him to the suffering caused by the disease. As a physician with a holistic perspective, Dr. Conant’s work expanded beyond the strictly clinical, to include education, research, and advocacy.


Dr. Conant is currently a clinical professor emeritus at the University of California Medical Center in San Francisco. Dr. Conant has published more than 70 articles on the treatment of AIDS, testified in front of Congress multiple times, and is a powerful advocate for the LGBTQ community.
