The first community health center in the United States was the Columbia Point Health Center in Dorchester. It was opened in December 1965 and served mostly the massive Columbia Point public housing complex adjoining it. It was founded by two medical doctors, Jack Geiger who had been on the faculty of Harvard University then later at Tufts University and Count Gibson from Tufts University. Geiger had previously studied the first community health centers and the principles of Community Oriented Primary Care with Sidney Kark and colleagues while serving as a medical student in rural Natal, South Africa. The Columbia Point Health Center is still in operation and was rededicated in 1990 as the Geiger-Gibson Community Health Center.
