The Gary & Barbara Siegler Foundation concentrates most of its giving on New York–based cultural and educational institutions, supplemented by support for family-focused social services and pooled philanthropic vehicles. Their portfolio combines one very large gift to a donor-advised/impact fund with several smaller, targeted grants to arts organizations and a private K–12 school, suggesting local, arts-and-education priorities and occasional support for direct social service programs.
A single five-figure gift dominates the foundation’s recent activity: $250,676 in 2025 to Morgan Stanley Global Impact Funding Trust Inc. That pooled-philanthropy contribution sits alongside a smaller set of targeted grants to New York cultural groups, a family-support organization, and a private school. The pattern points to a funder that mixes intermediary giving with direct support for institutions in arts, education, and community services. The Gary & Barbara Siegler Foundation C/o Perelson Weiner LLP gave $10,000 each to Shed NYC Inc and NYC Ballet Inc in 2023, both New York City arts organizations. It also supported Good Plus Foundation with a $25,500 grant in 2023 and made repeated $8,000 grants to The Cushman School in 2023 and 2025. Taken together, those awards show a portfolio centered on New York-based organizations, with one large allocation to a philanthropic vehicle and smaller grants to institutions serving families, students, and cultural audiences.
Arts and culture are a clear part of the portfolio. In 2023, the foundation gave $10,000 to Shed NYC Inc and another $10,000 to NYC Ballet Inc, both in New York City. Education is another recurring area. The foundation supported The Cushman School with an $8,000 grant in 2023 and a second $8,000 grant in 2025, indicating continued attention to the same private K–12 institution. Family-centered social support also appears in the record. Good Plus Foundation received $25,500 in 2023, placing basic needs and community support within the foundation’s grant mix. A separate piece of the portfolio goes through a pooled philanthropic vehicle: Morgan Stanley Global Impact Funding Trust Inc received $250,676 in 2025.
The typical grant size is tightly clustered: p25 is $9,500, median is $10,000, and p75 is $13,875. That middle range sits far below the largest grant, which went to a philanthropic intermediary in 2025. The record also shows repeat support for the same school across 2023 and 2025, while most other named recipients appear as single-year grants. The foundation does not fund individuals and does not make program-related investments. The grant list suggests direct charitable grants alongside at least one large pooled-philanthropy contribution, rather than a public application-based grant program.
