Mercy Haven, Inc.
Tonight, more than 4,500 Long Islanders, including nearly 1,500 children, will have nowhere to sleep. Many are living with mental illness, are disabled veterans, have multiple diagnoses, or are survivors of domestic violence.
They aspire to rebuild their lives, find jobs, and become part of a community, but they often don’t know where to start.
Since 1985, Mercy Haven has provided temporary and permanent housing and essential services to individuals and families in-crisis. Each year, we support over 400 adults and children, working to break the cycle of homelessness and reduce the stigma surrounding mental illness on Long Island.

Celebrating 40 Years of Service
For four decades, Mercy Haven has been a beacon of hope for Long Islanders facing homelessness, mental illness, and adversity. As we mark our 40th year, we remain committed to expanding our impact, providing safe housing, and fostering a supportive community for those in need. This milestone reflects the resilience of those we serve and the dedication of our supporters, volunteers, and staff.
Since 1970, our founder, Sister Patricia Griffith, has advocated for the Islip community, first as an elementary school teacher and later as a champion for the underserved in Bay Shore. She helped establish the Hospitality Center at St. Patrick’s Parish, supporting individuals recently mainstreamed from state psychiatric hospitals. Teaming up with Sister Kathy Nolan and a coalition of concerned citizens, they worked tirelessly to prevent residents from being displaced from the Baybright Hotel. From this urgent mission, Mercy Haven was born.
