About Mattis Family Foundation
The Mattis Family Foundation’s recent giving is anchored by repeated support for independent schools in Greenwich, especially Greenwich Country Day School and Eagle Hill School. Those grants sit at the center of a portfolio that combines larger education awards with smaller gifts to local civic, cultural, and public-interest institutions. In the latest grants list, the foundation made a $100,000 grant to Greenwich Country Day School and $25,000 to Eagle Hill School, while also continuing support for Greenwich Library, Neighbor to Neighbor, and Greenwich Historical Society.
The foundation’s pattern suggests a preference for institutions it can support over time rather than one-time national bets. Education appears to be the main thread, but the grant list also includes arts and culture, spiritual development, public media, emergency medical services, and food assistance. That mix shows a local philanthropic footprint with a few grants extending beyond Connecticut to schools, media, and cultural organizations in New York, California, Massachusetts, and New Jersey. The overall scale is moderate, with most grants clustered around $10,000 to $20,000 and a small number of larger education commitments.
What Mattis Family Foundation Funds
Education is the clearest through-line. The foundation gave $70,000 in 2023 and $25,000 in 2025 to Greenwich Country Day School, and it also supported Eagle Hill School with $50,000 in 2023 and $25,000 in both 2024 and 2025.
Independent-school support extends beyond Greenwich. Indian Mountain School received $35,000 in 2023, and The Peddie School received $20,000 in 2023 and another $20,000 in 2024. The foundation also funded the University of California Berkley Foundation for $20,000 in 2023 and University of California Berkley for $10,000 in 2024.
Beyond schools, the grant list includes community-facing work: Neighbor to Neighbor received $20,000 in 2024 and 2025, Greenwich Library received $10,000 in 2024 and 2025, and Greenwich Historical Society received $5,000 in 2024 and 2025.
