    About Alden Charitable Foundation

    The Alden Charitable Foundation concentrates its support on independent and parochial secondary schools, place-based cultural and preservation organizations (notably on Martha's Vineyard), and youth-development/mentoring programs. Grants skew toward capital or program support for schools and nonprofit cultural institutions, with a mix of multi-year/repeat commitments and smaller event or program gifts across a few geographic hubs (Guilford/New Haven CT, Martha's Vineyard, and select Florida cultural institutions).

    Focus Areas

    Catholic and independent secondary schools (e.g., Notre Dame High School, Sacred Heart Academy, Mercy High School)Martha's Vineyard community institutions and preservation (Preservation Trust, Museum, Regional High School, Agricultural Society)Botanic and historic cultural sites in Florida (Vizcaya Museum & Gardens, Fairchild Tropical Botanic Garden)Youth mentoring and workforce-readiness programs (Big Brothers Big Sisters, Year Up, Boys & Girls Club)Community arts and local festivals/support (Featherstone Center for the Arts; event funding like Festival of Laughs/food pantry support)

    Who They Fund

    About Alden Charitable Foundation

    Alden Charitable Foundation Inc backs a tight cluster of repeat recipients, with Notre Dame High School alone receiving $100,000 in 2025 after $70,000 in 2024 and $40,000 in 2023. That pattern points to a funder that favors sustained support rather than one-off gifts, especially for independent and Catholic secondary schools. The same approach shows up in other recurring grants: Sacred Heart Academy Inc received $25,000 in 2025 after earlier awards of $25,000 in 2024 and $20,000 in 2023, while Mercy High School also appears more than once in the recent grant list. The foundation also supports place-based cultural and preservation work, including museums, gardens, and local institutions tied to Martha’s Vineyard and Florida. Recent examples include Vizcaya Museum & Gardens Trust Inc and Fairchild Tropical Botanic Garden Inc, both funded for program support, alongside Featherstone Center for the Arts in Oak Bluffs. Youth-serving organizations also appear in the portfolio, including mentoring, child-welfare, and workforce-readiness groups such as Year Up Inc and Prevent Child Abuse America.

    What Alden Charitable Foundation Funds

    Education is a central theme in the foundation’s grantmaking. It gave $100,000 to Notre Dame High School for program support, $30,000 to Brooks-debartolo Collegiate High School, and $15,000 to St Augustine High School Foundation. Other school grants went to Sacred Heart Academy Inc and Mercy High School. Cultural and preservation institutions form another clear lane. The foundation awarded $40,600 to Vizcaya Museum & Gardens Trust Inc and $17,000 to Fairchild Tropical Botanic Garden Inc, both for program support, extending support for Florida cultural and horticultural sites. On Martha’s Vineyard, grants supported community institutions and local programming, including $18,250 to Featherstone Center for the Arts and $7,200 to Martha’s Vineyard Museum Inc. Youth and family services also appear through $10,000 grants to Year Up Inc and Prevent Child Abuse America.

    How Alden Charitable Foundation Gives
