Phoenix House was founded in 1967 as a therapeutic community to treat addiction in an 85th Street apartment in New York City. In the following decades, Phoenix House expanded to locations throughout New York City and ten states. At the time of the interviews, Phoenix House was serving over 5,000 individuals and remained committed to supporting individuals and families by providing a wide range of services including prevention, early intervention, treatment, continuing care, and recovery support. The Phoenix House Oral History Collection documents three periods of Phoenix House's work: origins, growth, and established leadership. In the first period, spanning from 1967 to the 1970s, narrators detail the founding of a therapeutic community, the dynamics of this community, and the influences of other self-help drug treatment organizations such as Synanon on the program. In the growth period, narrators speak of opening up new facilities, and designing and launching new programs. Topics covered include the political and funding challenges of expanding Phoenix House's reach, increases in medical and mental health staff, and partnering with state departments of corrections to provide the Phoenix House program as an alternative to incarceration. In the final period, narrators describe changes in the therapeutic community model, further expansion of programs across the United States, acquisitions of competitors, new funding challenges, and transitions in leadership.
