Our Executive Director

Since 1970, Sister Pat has been a dedicated advocate for the Islip community, first as an elementary school teacher and later as a champion for the underserved in Bay Shore. She was key in establishing the Hospitality Center at St. Patrick’s Parish, supporting individuals recently mainstreamed from state psychiatric hospitals.

​

While the deinstitutionalization movement aimed to reintegrate people into their communities, a lack of resources left many struggling to transition. In 1985, when the Town moved to close a building housing over 100 former psychiatric patients, Sister Pat and a group of committed volunteers quickly mobilized, learning the complexities of advocacy and navigating government systems to protect those at risk.

​

Teaming up with Sister Kathy Nolan and a coalition of concerned citizens, they worked tirelessly to prevent the displacement of residents at the Baybright Hotel. From this urgent mission, Mercy Haven was born.

​

Over the past 39 years, Mercy Haven has grown from its grassroots beginnings into a vital agency that provides housing and essential support services to more than 400 individuals, including 83 children, across Long Island. Under Sister Pat’s leadership, the organization expanded from operating three community residences for individuals living with mental illness to a comprehensive network of housing solutions. Today, Mercy Haven manages 65 sites, offering 119 housing units for 339 adults and children in crisis, including veterans, disabled individuals, low-income families, and the elderly.

​

At its core, Mercy Haven believes that everyone deserves a safe, supportive community. With unwavering dedication, the organization continues to advocate for those facing poverty and mental illness, working to dismantle stigma and build a future where dignity, stability, and opportunity are accessible to all.
