About Jack Joseph & Morton Mandel Foundation
The Mandel Foundation is a Cleveland-rooted philanthropist that concentrates resources on strengthening Jewish communal life (locally and in Israel), civic and cultural institutions in Greater Cleveland, leadership development, and major health and conservation projects. Their portfolio mixes large capital and endowment gifts to flagship institutions with recurring project and operating support to Jewish federations, arts organizations, education and local neighborhood organizations. The foundation favors long-term institutional partnerships and leadership/organizational capacity building alongside place-based investments in Cleveland-area civic infrastructure.

About Jack Joseph & Morton Mandel Foundation
A defining feature of the Jack Joseph & Morton Mandel Foundation is the scale of its annual operating support for Mandel Foundation - Israel, which reached $35,080,374 in 2025 and $27,903,960 in 2023. That recurring commitment points to a foundation that uses major institutional grants to sustain long-running work rather than relying only on small project awards. The same pattern appears in its support for Cleveland-based institutions: the Cleveland Clinic Foundation received endowment funding in multiple years, and the Musical Arts Association received a mix of endowment, operating, and capital support over time. The foundation’s recent grant list also shows substantial funding for Jewish federations and Jewish civil-society organizations, including Jewish Federations of North America, American Jewish Joint Distribution Committee, Secure Community Network, and Jerusalem Foundation Inc. Across these grants, the foundation combines broad Jewish communal support, Israel philanthropy, health, arts, and civic investment. Its portfolio is also anchored by leadership development programs and long-term institutional partnerships, with grants that recur across years and often support operating stability, endowment growth, or capital needs rather than one-off program experiments.
What Jack Joseph & Morton Mandel Foundation Funds
Leadership development is one of the foundation’s clearest programmatic through-lines. In 2023, it gave $7,469,085 to Mandel School for Educational Leadership in Jerusalem for annual operating support, and the same organization received $3,769,688 in 2023 for the same purpose. The foundation also supports educational pipelines through fellowship-style programs such as the Mandel/Myers Fellowship, the Educational Leadership Program, and the Early Career Educators Program. Jewish communal infrastructure is another major focus. It awarded $3,083,500 to Jewish Federations of North America in 2025 for program support, after a $2,875,000 award in 2024 for program support. Community security appears as well, with a $2,200,000 grant to Secure Community Network in Chicago for project support. Arts and culture are part of the picture too, including support for cultural leadership and Jewish arts institutions.
How Jack Joseph & Morton Mandel Foundation Gives
The foundation’s typical grant size is modest relative to its largest awards: the p25 is $5,000, the median is $15,000, and the p75 is $100,000. At the same time, the recent grants list shows repeated multi-million-dollar awards to major institutions, indicating a dual pattern of small grants and large anchor commitments. The portfolio is not built around one-off transactions; multiple recipients appear across several years, including ongoing support to the same Cleveland, Jerusalem, and national institutions. The foundation is a regular funder, not a DAF, and it does not fund individuals or make program-related investments. Recent grants include operating support, project support, capital campaigns, endowment funding, contribution funding, and general operating support.
