Lower Eastside Neighborhoods Association.

LENA was founded in 1955 by a group of social agencies (among them Henry Street Settlement), civic organizations, churches, and individuals on New York's Lower East Side to combat juvenile delinquency and, later, to work for improved housing, recreation, and health facilities in the neighborhood.
