The Koschitzky Family Foundation concentrates almost all of its giving on Jewish communal life and philanthropic infrastructure, primarily supporting major Chicago Jewish institutions and a single Israel-focused fund. Most dollars go to a handful of repeat grantees, with occasional smaller gifts supporting Jewish religious/health initiatives.
Highly concentrated giving: a few large grants account for the vast majority of dollars, with repeat multi-year or multi-grant support to core grantees rather than many small, one-off gifts.
Jewish Federation of Metropolitan Chicago, Friends of Asor Fund US Inc, Halachic Organ Donor Society, Jewish United Fund of Metropolitan Chicago
The Tamar & Jonathan Koschitzky Family Foundation’s largest recent grant was $600,000 to Jewish Federation of Metropolitan Chicago for general operating support, underscoring a pattern of large unrestricted gifts to Jewish communal institutions. Across the recent grants on file, the foundation backs a small set of repeat recipients rather than a wide, dispersed portfolio, with support flowing to major Chicago organizations and one Israel-focused fund. That mix points to a funder that prioritizes organizational stability and core operations over project-specific awards. Two recipients appear more than once in the recent record. Jewish Federation of Metropolitan Chicago received multiple general operating support grants, including the top award in 2025 and another large gift in 2024. Friends of Asor Fund US Inc also received repeated support, including awards in both 2024 and 2025, indicating an ongoing relationship with an Israel-connected charitable vehicle. Smaller grants extend the same pattern to Jewish United Fund of Metropolitan Chicago and Halachic Organ Donor Society, both also supported through general operating support.
The foundation’s giving is centered on organizational capacity and operational infrastructure. In Chicago, it gave $600,000 to Jewish Federation of Metropolitan Chicago in 2025 for general operating support, and it also supported Jewish United Fund of Metropolitan Chicago with a $6,000 general operating grant in 2024. Those awards show attention to the core budgets of established communal institutions. A second thread is Israel-linked philanthropy. Friends of Asor Fund US Inc received $500,000 in 2024 and $250,000 in 2025, both for general operating support, suggesting sustained backing for that vehicle. The portfolio also reaches into Jewish bioethics and organ donation advocacy. In 2024, the foundation granted $25,000 to Halachic Organ Donor Society for general operating support, extending the same unrestricted funding approach to a smaller nonprofit.
Typical grant size is substantial: the distribution shows a 25th percentile of $156,250, a median of $225,000, and a 75th percentile of $500,000. The recent record also shows repeat support to the same organizations across multiple years, especially for Jewish Federation of Metropolitan Chicago and Friends of Asor Fund US Inc. Grants are framed as general operating support, with no sign of program-related investments. The foundation is associated with leadership by Jonathan Koschitzky.
