GSP is a not-for-profit AIDS Service Organization founded near the start of the AIDS epidemic in 1985. Begun by volunteers who gathered in a church basement, GSP is Kansas City’s oldest and most comprehensive agency exclusively devoted to the care and prevention of HIV/AIDS. The agency maintains a staff of more than 20 professionals and over 100 volunteers. The service area consists of 11-counties in greater Kansas City. GSP offices are located in Kansas City, Missouri, and in Kansas City, Kansas.
