The David & Sheila Cornstein Foundation concentrates its giving on New York–connected educational institutions and Jewish communal life, with a secondary interest in Jewish-affiliated social services. Major gifts fund elite K–12 and professional education (multiple multi-year gifts) and synagogue support, indicating a preference for established institutions and organizations with personal or community ties to the donors.
The David & Sheila Cornstein Foundation’s largest recent grant went to Horace Mann School, including a $70,000 gift in 2024 after a $60,000 grant in 2023. That repeated support signals a pattern of backing established institutions over time, especially in New York-connected education. The foundation also made sustained gifts to New York Law School, with $20,000 grants in 2023, 2024, and 2025, showing a similar multi-year approach in professional education. Beyond schools, the foundation’s giving reaches Jewish communal institutions and affiliated services. Park East Synagogue received $26,600 in 2023 and $20,000 in 2024, while Morse Life Foundation received $2,500 in 2023, $10,000 in 2024, and $17,500 in 2025. Those grants point to a donor pattern centered on long-standing organizations with visible community roles. The portfolio also includes smaller gifts to universities, health organizations, and local Jewish and community groups, but the recurring feature is concentration: the foundation favors a limited set of organizations and returns to them across multiple years.
In elite independent K–12 education, the foundation gave $70,000 in 2024 to Horace Mann School in Bronx, NY, following a $60,000 grant in 2023. That same preference for established institutions appears in legal education, where New York Law School in New York, NY received $20,000 in 2023, $20,000 in 2024, and $20,000 in 2025. Jewish communal life is another clear theme. Park East Synagogue in New York, NY received $26,600 in 2023 and $20,000 in 2024, and Palm Beach Synaogue in Palm Beach, FL received $6,800 in 2024 and $5,000 in 2025. The foundation also supports Jewish-affiliated eldercare and social services: Morse Life Foundation in West Palm Beach, FL was funded in 2023, 2024, and 2025, including a $17,500 grant in 2025. Smaller gifts extend to New York-based civic and health-related groups such as Courts of Dreams Inc, Columbia University Irving Medical Center, and Friends of United Hatzalah.
Typical grant sizes are modest to mid-sized, with a p25 of $1,000, a median of $2,500, and a p75 of $10,000. The foundation’s pattern is relationship-based and recurrent: several recipients appear across multiple years, including grants in 2023, 2024, and 2025 to the same organizations. It is a private foundation rather than a grantmaking vehicle for individuals, and the record does not indicate an open application process.
