Ideal Applicant
A small or local nonprofit (often community, cultural, or faith‑based) in Connecticut or nearby New York seeking a modest, program‑specific grant and able to apply by a concise mailed letter or phone contact.
Good Fit
- • Based in CT or nearby NY and serving local community needs.
- • Project requests are modest and tied to specific program activities.
- • Has local credibility or an existing relationship/referral to the foundation.
- • Can submit a clear, concise letter describing purpose on a rolling basis.
Geography
Giving is regionally concentrated: the latest year covered two states (CT and NY) with about 59% of dollars staying in Connecticut, and historical filings show a strong in‑state focus.
Recipient Variety
The foundation funded multiple independent recipients each year (14 in 2022, 22 in 2023, 8 in 2024) and six grantees recur across years, indicating a moderate diversity of independent recipients rather than a tiny closed circle.
New Applicants
Direct evidence of long‑term turnover is limited but filings show new grantees in recent years (notably 17 new in 2023 and 2 new in 2024) and a rolling, letter‑based submission route exists; selection still appears relationship‑aware rather than broadly open.
