The Leone Family Foundation makes a small number of very large, unrestricted gifts to high‑profile, institutionally prestigious organizations. Their giving supports elite higher education, leading medical institutions, and a local independent Catholic secondary school, suggesting a mix of national philanthropic reach and support for local faith‑based education. Grants are directed as general charitable/purpose funding rather than narrowly restricted program grants.
Concentrated giving: very few, large unrestricted grants to established, high‑profile institutions rather than many small or grassroots organizations; appears to favor prestige organizations and local faith‑based education.
A $1,000,000 grant to Stanford University Development Services stands out in the Leone Family Foundation’s recent record and points to a pattern of large, discretionary gifts to institutionally prominent organizations. The foundation also made a $510,000 grant to Memorial Sloan Kettering and a $405,000 grant to Delbarton School, showing support across higher education, medical care, and faith-based secondary education. Recent awards are labeled for general charitable purposes, which gives recipients broad flexibility in how funds are used. That same pattern appears in smaller gifts to organizations such as Facing History and Ourselves, Environmental Defense Fund, and The Catholic Charities of The New York. The foundation’s portfolio includes national names alongside New Jersey-based institutions, including Oak Knoll School, Summit Area YMCA Summit, Temple Bnai Jeshurun, and Wyckoff Family YMCA. The overall picture is of a family foundation making selective grants rather than a high-volume, issue-specific program. Its recent giving mixes large anchor commitments with repeat support to certain institutions, especially in education and community service.
In higher education, the foundation gave $1,000,000 to Stanford University Development Services for general charitable purposes and $25,000 to Georgetown University for the same broad designation. Those gifts show support for major university institutions rather than a single named program. Medical philanthropy is another visible thread. Memorial Sloan Kettering received $510,000 in 2024, again for general charitable purposes, placing a top cancer center among the foundation’s largest recent recipients. Faith-based and independent schooling also appears repeatedly. Delbarton School received $405,000 in 2025, plus additional grants of $93,000 and $50,000 in prior years, while Oak Knoll School received $100,000. Community-serving organizations appear as well, including Crossroads Community Services Inc and Moms Helping Moms. The recent grants also include civic, environmental, and educational-access organizations such as Reform Alliance, Environmental Defense Fund, and Summer Search.
The typical grant size is $5,338 at the 25th percentile, $10,299 at the median, and $24,000 at the 75th percentile, but the recent record also includes much larger outliers in the hundreds of thousands and a $1,000,000 award. The foundation appears to favor flexible grants labeled for general charitable purposes. Repeat support is visible: Delbarton School received multiple grants across 2023, 2024, and 2025, and The Pingry School also appeared in both 2024 and 2025. That suggests some ongoing relationships rather than one-time awards. The foundation does not fund individuals and does not make program-related investments.
