Greenhope was established in 1975 in a convent that was transformed into a comprehensive residential treatment program for formerly incarcerated women. Over the years, it has developed formal relationships with the criminal justice system and has expanded its work to include services for women on parole and those referred by the courts as an alternative to incarceration (ATI).

Located in East Harlem, Greenhope's commitment to providing quality services to predominantly poor African American and Latina ex-offenders has made it a leader in working with women to address the problems that lead to a life of drugs and crime. It is one of the few woman-centered facilities operating in New York State, which serves both parolees and ATI clients.

Greenhope operates three programs: Residential Treatment, Day Treatment, and Outpatient Services. In addition to its treatment focus, Greenhope is actively involved in local and statewide policy and advocacy efforts that address the specific needs of women in prison. Greenhope serves over 200 women annually.

To date, Greenhope has helped over 4,000 women reclaim their lives, reunite with their families and rebuild their communities.
