The Iris & Saul Katz Family Foundation concentrates its philanthropy exclusively on hospital/health system support, making large general contributions to Northwell Health System Foundation. Grants are directed toward sustaining regional healthcare capacity and operations rather than a broad mix of causes. The foundation appears locally focused on major medical institutions serving the Long Island/New York area.
Highly concentrated: very few grants (three) totaling several million dollars, all to a single repeat grantee (Northwell Health System Foundation), indicating large, targeted gifts to one primary beneficiary rather than distributed small grants.
Northwell Health System Foundation
Iris & Saul Katz Family Foundation Inc. centers its giving on hospital and health system support, with repeated general contributions to Northwell Health System Foundation in 2023, 2024, and 2025. That pattern points to a funder that backs core operations and regional healthcare capacity rather than a broad portfolio of issue areas. The foundation’s largest recent grant, $2,495,845 in 2025, went to Northwell Health System Foundation in New Hyde Park, NY. The prior two years show the same recipient at $2,192,230 in 2024 and $2,184,762 in 2023, reinforcing a steady relationship with a major medical institution serving Long Island and the New York region. Beyond that anchor grant, the foundation’s recent awards include support for The Viscardi Center in Albertson, NY and Island Harvest in Bethpage, NY, both of which received multiple gifts. The overall pattern is local, institution-based philanthropy, with grants clustered around organizations tied to health, community services, and regional infrastructure. The foundation also appears to favor unrestricted or general-contribution support, based on the language used across its recent grants.
Health system support is the clearest theme in the recent record. In 2024, the foundation gave $175,000 to The Viscardi Center in Albertson, NY, and followed with $67,500 in 2025, both as general contributions. Food access and community support also appear in the portfolio. Island Harvest in Bethpage, NY received $100,000 in 2023, $100,000 in 2024, and $100,000 in 2025, showing a repeated commitment to the same organization. The foundation has also supported Jewish and community institutions. It gave $100,000 to Uja Federation of NY in New York, NY in 2023, and made a $69,900 general contribution to Congregation Tifereth Isreal in Glen Cove, NY in 2025. Education-related grants are present as well, including $110,000 to The Green Vale School in Glen Head, NY in 2023.
The recent grant distribution is tightly clustered around smaller awards, with a p25 of $2,000, a median of $3,600, and a p75 of $10,000. That said, the foundation also makes occasional much larger general contributions, especially to a major health-system recipient. The giving pattern is recurring rather than one-off: several grantees appear in multiple years, including the same hospital foundation and several local nonprofits. The foundation is a private family foundation, based on its name and structure, and it does not fund individuals or make program-related investments.
