MercyFirst is a not-for-profit human service agency serving more than 3,200 children, teenagers and families each year in New York. Founded as an orphanage in the late 1800s by the Sisters of Mercy, today MercyFirst offers a continuum of care through its network of programs in New York City and on Long Island. We strive to provide a healing interval in the lives of the children and families we serve. We offer a safe environment, in an effort to develop their full potential.
