Callen-Lorde's grassroots heritage dates back over 40 years to the St. Mark's Community Clinic and the Gay Men's Health Project, two volunteer-based clinics that provided screening and treatment for sexually-transmitted diseases. These clinics merged in 1983 to form Community Health Project, a mostly volunteer-staffed, episodic care program housing the nation's first community-based HIV clinic.
