Marc J Leder Foundation Inc’s recent giving is marked by several large, repeated grants to medical and biomedical organizations, especially cancer-focused institutions and health systems. In 2025, the foundation gave $800,000 to Boca Raton Regional Hospital Foundation Inc for general support and $658,271 to The Trustees of the University of Pennsylvania for general support, showing a mix of local hospital backing and university-based research support. The same pattern appears in earlier years: the University of Pennsylvania received another $610,000 in 2023, while Samuel Waxman Cancer Research Foundation received $250,000 in 2023 and again $250,000 in 2025. The foundation also appears as a steady funder of organizations tied to clinical care, cancer research, and higher education, including rabin medical center support through The American Friends of Rabin Medical Center and health-related giving in Boca Raton. Its grantmaking is not limited to one institution type; it includes hospitals, research foundations, universities, and select community organizations. Several grants are framed as general support or to fund the charitable purpose of the organization, suggesting flexible support alongside more targeted research philanthropy.
Cancer research is one of the clearest themes in the foundation’s giving. It awarded $250,000 in 2025 to Samuel Waxman Cancer Research Foundation for general support, and another $104,000 in 2025 to Gabrielle's Angel Foundation for Cancer Research Inc for general support. Earlier grants also went to Breast Cancer Research Foundation and Richard David Kann Melanoma Task Force Inc. Medical and hospital support is another major area. The foundation gave $800,000 in 2025 to Boca Raton Regional Hospital Foundation Inc for general support, and it also supported local health-related groups such as Boca Raton Police Foundation and Rotary Club Downtown Boca Raton Fund Inc. Higher education appears through grants such as $658,271 in 2025 to The Trustees of the University of Pennsylvania and $25,000 in 2023 to School of American Ballet Inc. The foundation also backs selected Jewish and Israel-related institutions, including $100,000 in 2023 to The American Friends of Rabin Medical Center and $25,000 in 2025 to Anti-Defamation League.
