United Bronx Parents (UBP) was founded in 1965 as a grassroots organization of parents and local businesses advocating for improved education for children in South Bronx public schools. In 1984, under executive director Lorraine Montenegro, the organization shifted focus to address other issues facing Bronx residents, including homelessness, substance abuse, and HIV/AIDS. The United Bronx Parents, Inc. Records document the organization's work for social services in the Puerto Rican community of the South Bronx from the 1960s to the 2010s.
