The Greenbaum Foundation
Samuel J. Greenbaum established The Greenbaum Foundation as a vehicle for his family's charitable giving, drawing on wealth accumulated through the Greenbaum family's long association with Owens & Minor, a Fortune 500 medical and surgical supply distributor. The foundation operates from offices in New York and West Hollywood, reflecting the family's bi-coastal presence. The foundation's grantmaking focuses on healthcare—particularly medical research and hospital support—alongside Jewish communal organizations, education, and arts institutions. Named beneficiaries include Mount Sinai Medical Center, the Jewish Federation of Greater Los Angeles, and the Museum of Jewish Heritage (per public records). It does not operate a public investment mandate; its assets are managed to support ongoing charitable distributions. No recent operational events have been publicly reported. The foundation's leadership remains with Samuel J. Greenbaum as chairman and his wife Michele Greenbaum as president, roles they have held since its founding. The foundation has not disclosed assets or annual grant totals. Structural differentiator: The Greenbaum Foundation operates strictly as a grant-making philanthropic entity, not an investment vehicle—distinct from many family offices that combine charitable giving with direct equity or venture investing. Its bi-coastal presence in New York and West Hollywood reflects the Greenbaum family's geographic footprint.
