The Martin & Toni Sosnoff Foundation concentrates large, strategic gifts to elite cultural, higher education, and medical institutions—primarily in New York—favoring performing arts organizations, liberal arts higher education, and biomedical research/health systems. Their funding pattern shows multi-year and repeat support to a small set of high-profile institutions rather than many small grants, signaling a preference for transformational gifts to well-established organizations.
A $4.35 million gift to Bard College in 2024 stands out as the foundation’s largest recent grant and a clear signal of how the Martin & Toni Sosnoff Foundation gives: concentrated, high-value support to a small set of named institutions. Its recent record shows sustained funding for performing arts organizations, liberal arts higher education, and academic medicine, with repeat awards often appearing in consecutive years. The foundation backed American Ballet Theatre in both 2023 and 2024, and it also supported the New York Philharmonic, Palm Beach Opera, and Miami City Ballet, pointing to a consistent interest in major performing arts institutions. In higher education, Bard College received both a seven-figure grant and another substantial award in 2023. In health and research, the foundation supported Mount Sinai Health System, Icahn School of Medicine at Mount Sinai, and The New York Eye & Ear Infirmary of Mount Sinai. The pattern is institution-focused rather than broad or diffuse. Grants cluster around established cultural, educational, and medical organizations, including several in New York and Palm Beach-area institutions.
In performing arts, the Martin & Toni Sosnoff Foundation funded American Ballet Theatre with $575,000 in 2023 and $500,000 in 2024. It also gave $333,000 to the New York Philharmonic in 2024, along with support for Palm Beach Opera, Miami City Ballet, Chamber Music Society of Palm Beach, and Palm Beach Dramaworks. In higher education, Bard College received $4.35 million in 2024 and $268,500 in 2023. Hofstra University also appeared in consecutive years, with $15,000 in both 2023 and 2024. In medicine and biomedical institutions, the foundation gave $450,000 to Mount Sinai Health System in 2024 and $425,000 to Icahn School of Medicine at Mount Sinai in both 2023 and 2024. It also supported New York Presbyterian and The New York Eye & Ear Infirmary of Mount Sinai.
Typical grants fall in a wide range, with p25 at $10,000, a median of $29,000, and p75 at $100,000. The recent grants list shows both smaller awards and very large, strategic gifts, including a seven-figure-level outlier. Recipients often appear across multiple years, indicating repeat support rather than one-time giving. The foundation does not fund individuals and makes no program-related investments. Its pattern is institutional support to established organizations, with charitable grants as the dominant form.
