The BRA subsequently reevaluated its approach to urban renewal in its future projects, including the construction of Government Center. In 1965, the first Community Health Center in the United States opened, the Columbia Point Health Center, in the Dorchester neighborhood. It mostly served the massive Columbia Point public housing complex adjoining it, which was built in 1953. The health center is still in operation and was rededicated in 1990 as the Geiger-Gibson Community Health Center. The Columbia Point complex itself was redeveloped and revitalized into a mixed-income community called Harbor Point Apartments from 1984 to 1990. By the 1970s, the city's economy boomed after 30 years of economic downturn. A large number of high rises were constructed in the Financial District and in Boston's Back Bay during this time period. This boom continued into the mid-1980s and later began again. Hospitals such as Massachusetts General Hospital, Beth Israel Deaconess Medical Center, and Brigham and Women's Hospital lead the nation in medical innovation and patient care. Schools such as Boston College, Boston University, the Harvard Medical School, Northeastern University, Wentworth Institute of Technology, Berklee College of Music and Boston Conservatory attract students to the area. Nevertheless, the city experienced conflict starting in 1974 over desegregation busing, which resulted in unrest and violence around public schools throughout the mid-1970s.
