I am not surprised that this fine organization is not recognized in your directory of nonprofits. This organization has over approximately 30 years quietly helped to provide affordable low income housing to the working poor in Spanish Harlem, New York. Originally starting as a tenant advocacy group the organization evolved into a housing construction organization initially by rehabilitating run down tenements using low income tax credit funding and later shifting into new construction building the first new homes built in Spanish/East Harlem in 60 years. They are currently involved in the rehabilitation of an old public school structure (P.S. 109) built in approximately 1898 that was slated for demolition. Instead, Fightback joint ventured with another nonprofit, Artspace of Wisconsin, to secure funding that would allow the building to be rehabilitated to its former glory and provide affordable housing for artists. More recently, in an effort to help tenants and other local community members find employment Fightback has started a Home Health Aide training program that certifies its graduates and helps place them into meaningful employment opportunities.
I have included a link to a Youtube video that provides a brief history of this wonderful organization.
