Marjorie Hill, assistant commissioner for HIV/AIDS services at the New York City Department of Health and Mental Hygiene, last week announced her resignation from the department to accept a position at Gay Men's Health Crisis, the nation's oldest AIDS service organization. Deputy HIV/AIDS services director Jan Carl Park was named acting commissioner in Hill's place. Health commissioner Thomas Frieden says a national search has been launched for Hill's replacement. Hill will work at GMHC to help the agency expand its services to women and families affected by HIV. "In my new role, I eagerly anticipate exploring innovative approaches to strengthening the agency's multifaceted response to the epidemic as it affects the lives of women and families--an underserved and too frequently invisible population when it comes to HIV and AIDS," Hill said in a press statement.
