The Corey Foundation concentrates large, targeted gifts in health care and higher education with an emphasis on regional impact on Long Island and a secondary interest in international humanitarian relief. The single largest commitment funds Peconic Bay Medical Center, while substantial repeat grants support Operation International and Stony Brook University, indicating a mix of local institutional investment and overseas humanitarian giving.
A $4,105,500 grant to Peconic Bay Medical Center Foundation stands out as the Corey Foundation’s defining recent commitment, showing how strongly the funder backs health care infrastructure and patient care on eastern Long Island. The foundation pairs that kind of large institutional support with repeat giving to humanitarian relief, including multiple grants to Operation International in both 2023 and 2024. Education is another consistent pillar: Stony Brook Foundation and Stony Brook University Foundation each appear with substantial support tied to university programs and research. Alongside those larger commitments, the Corey Foundation also funds community-serving organizations such as Riverhead Free Library, Bowery Residents' Committee, and Maureen's Haven, suggesting a mix of hospital investment, higher education support, and local service delivery. Its grant list also includes arts and research recipients, but the strongest pattern is a concentrated portfolio centered on health care, humanitarian response, and regional institutions with Long Island ties.
Health care is the clearest theme in the Corey Foundation’s giving. In 2024, it gave $152,500 to Peconic Bay Medical Center Foundation for health care, following a much larger 2023 grant of $4,105,500 to the same organization. Humanitarian relief is another recurring area: the foundation awarded $1,100,000 to Operation International in 2024 and $572,982 in 2023, both tagged humanitarian. It also supported Bowery Residents' Committee with $100,000 for homelessness, showing an interest in direct services for people in crisis. Education and research appear through grants such as $346,107 to Stony Brook Foundation and $25,000 to Tesla Science Center for research, indicating support for university-linked programs and scientific work.
The Corey Foundation’s grants are mostly in the low-to-mid five-figure range, with a typical gift size of $5,000 at the 25th percentile, $10,000 at the median, and $25,000 at the 75th percentile. The distribution is uneven because a small number of large awards sit above a broad base of modest gifts. Recipients also recur across years, including Operation International, Stony Brook University Foundation, Peconic Bay Medical Center Foundation, East End Hospice, Maureen's Haven, and Tesla Science Center. The foundation does not fund individuals and does not make program-related investments. Its giving is local in scope, and the grant list shows a strong concentration in New York.
