MercyFirst is one of New York's leading not-for-profit human service agencies serving more than 4,000 children, teenagers and families each year in Brooklyn, Queens, Nassau and Suffolk counties.
Founded by the Sisters of Mercy as sister orphanages, Angel Guardian Home in Brooklyn and St. Mary's of the Angels Home in Syosset, we have provided hope and refuge to children who had little else since the late 1800s. Today we are a multi-service agency offering a comprehensive and integrated continuum of care through a network of more than 20 service locations in New York City and throughout Long Island.
