The Muriel F. Siebert Foundation concentrates its modest philanthropic giving into a very small number of substantial gifts to major institutional recipients, primarily in healthcare and higher education. Over the reported period it split funding almost evenly between a university-affiliated health foundation and Columbia University for general support and scholarships, indicating a priority on institutional medical support and postsecondary scholarship/academic advancement.
Highly concentrated giving: very few (two) relatively large grants that split the foundation's reported budget roughly 50/50. Funds go to established institutional recipients rather than many small or community-based grantees; emphasis on core, general-support and scholarship-type awards.
Muriel F Siebert Foundation Inc’s recent giving centers on institutional support for higher education and healthcare, with the largest listed awards going to University Health Foundation in San Antonio and Trustees of Columbia University in New York. Those grants point to a pattern of backing universities, university-affiliated health institutions, and scholarship funds rather than a wide mix of small community awards. The foundation’s records also show repeated support for Lewis & Clark College, including $100,000 in 2025 and prior gifts of $75,000 and $50,000, alongside annual support for Columbia University in 2023 and 2025. In healthcare, New York Presbyterian Hospital received $75,000 for a cardiology fellowship, showing that some of the giving is directed to training within medical institutions. Beyond those anchor relationships, the foundation funded a small set of other nonprofits with general support, including Girl Scouts of Southwest Texas, After School All Stars, and the Eleanor Roosevelt Val-Kill Partnership. The overall picture is of a donor that concentrates its grants into a limited number of established institutions, often for general operating support or scholarship-related purposes.
Higher education is a clear priority. The foundation gave $112,000 to Trustees of Columbia University in 2025 for general support and scholarship funds, and it also awarded $100,000 to Lewis & Clark College in 2025 for general support. Healthcare funding appears in a separate line of giving. New York Presbyterian Hospital received $75,000 for a cardiology fellowship, indicating support for advanced medical training rather than only direct service delivery. General operating support is another recurring theme across the recent grants list. Examples include $60,000 to Girl Scouts of Southwest Texas, $50,000 to After School All Stars, and $40,000 to the Eleanor Roosevelt Val-Kill Partnership, each designated for general support.
Typical grant size is $3,000 at the 25th percentile, $5,000 at the median, and $10,000 at the 75th percentile, but the recent grants list also includes much larger institutional awards above $100,000. The foundation is a regular funder and appears to support recipients across multiple years: Columbia University, Lewis & Clark College, and Nys Outward Bound Schools each received more than one grant in the recent record. It funds individuals, and its recent giving includes both program-specific support and general operating support. No application process is shown in the provided data.
