Ideal Applicant

An established charitable organization (often New York–based) with a prior relationship or referral to the trustees, seeking modest unrestricted operating support or program grants aligned with the foundation’s past giving (health, education, local environment, arts/culture).

Good Fit

  • Established nonprofit with an existing relationship or introduction to a trustee or their network
  • Based in New York or has demonstrable program activity in New York
  • Seeking modest general operating or program support in the foundation’s typical grant-size range
  • Mission areas matching past grantees (health, education, local land/conservation, arts, community service)
  • Clear evidence of financial stability and outcomes to justify repeat support

Geography

Moderate

Grants appear across multiple states (about seven states observed), but spending is concentrated in New York, which received roughly 67% of the latest year's dollars.

Recipient Variety

Broad

The foundation supported about 23–28 distinct independent recipients each year, indicating a broad recipient set for a micro private foundation despite some dollar concentration among the top grantees.

New Applicants

Restrictive

Direct evidence shows very limited onboarding of new grantees (only two new recipients in the latest year) and the foundation explicitly states it funds only preselected applicants, so unfamiliar organizations are unlikely to enter the portfolio without a prior introduction.
