Dr. Olivieri watched attentively and with concern as the decade of the 1980s unfolded with its growing unrest and lack of knowledge regarding the HIV epidemic. Noticing, too, that some of the negative attitudes regarding HIV had spread to the medical community and that patient treatments were being compromised as a result, Dr. Olivieri took action. He joined St. Vincent’s Hospital as an HIV Scholar for the AIDS Institute, then transitioned to the NYU Medical Center as Physician for the HIV Clinic, and soon worked his way up to HIV Medical Director at Greenwich House.
