The David & Sondra Mack Family Foundation concentrates its giving on a small number of large institutional gifts, primarily supporting higher education, regional healthcare, and Jewish communal life in the New York/New Jersey area. The foundation makes sizable, targeted grants (including repeat funding) to major institutions rather than many small community organizations, indicating a preference for capacity-building or capital/exempt-purpose support to established nonprofits.
Highly concentrated: very few grants (4) with large dollar amounts, repeat major funding to the same beneficiary (Hofstra receives multiple grants), focused on institutional/exempt-purpose gifts rather than many small operational awards.
Notable grantees: Hofstra University, Northwell Health Foundation, Temple Israel
A defining feature of The David & Sondra Mack Family Foundation Inc is its concentration on large institutional gifts, with repeated support for Hofstra University, Northwell Health Foundation, and Temple Israel. The pattern points to exempt-purpose funding for established organizations rather than broad grassroots grantmaking. Recent awards include $1,102,500 to Hofstra University in 2023 and $925,000 in 2025, alongside $810,000 to Northwell Health Foundation in 2023. Those grants sit within a broader portfolio that also reaches Jewish communal institutions, regional healthcare, and select civic and cultural nonprofits. The foundation’s giving appears especially tied to higher education and Jewish life in the New York and Florida corridor, with Temple Israel in Great Neck receiving both a $126,616 grant in 2023 and a $277,170 grant in 2025. Other sizable awards include support for the Kravis Center in West Palm Beach and Jewish Federation in New York, reinforcing a preference for organizations with institutional scale and defined exempt-purpose projects.
Higher education is one of the clearest threads in the foundation’s recent grants. Hofstra University received $1,102,500 in 2023 and $925,000 in 2025, both listed as exempt-purpose support. Healthcare is another major area: Northwell Health Foundation was awarded $810,000 in 2023 and $112,000 in 2025, showing repeated backing for a regional health system. Jewish communal institutions also appear prominently. Temple Israel in Great Neck received $126,616 in 2023 and $277,170 in 2025, while Jewish Federation in New York was funded at $105,000 in 2023 and $115,000 in 2025. The portfolio also includes support for Temple Emanu-el in New York, Met Council, and Uja Federation of New York, indicating an emphasis on established communal infrastructure.
Typical grants are modest in the middle of the distribution but skew wide: the p25 is $1,500, the median is $3,400, and the p75 is $10,000. The recent-gift list shows that the foundation also makes much larger exempt-purpose awards to a smaller set of institutions, suggesting a dual pattern of many small grants and a few major commitments. Several recipients appear in multiple years, including Hofstra University, Northwell Health Foundation, Temple Israel, Temple Emanu-el, Jewish Federation, Uja Federation of New York, Kravis Center, Washington Institute, and The Society of the Four. The foundation does not fund individuals and does not make program-related investments.
