This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The Dinan Family Foundation does not accept unsolicited requests, so a cold application is unlikely to be considered; the only route the filing describes is an invitation, so a grant writer should not expect an open call to succeed.
  • Most of its grants are modest: about 8 in 10 fall between $1,800 and $200,000, and half of its 162 grants are $10,000 or less, so a request in that range fits its usual pattern, although its largest grant was $2,050,000, so that band is not a ceiling.
  • Repeat giving is strong, with 93% of its grant dollars going to organisations it had also funded in its earlier filings, so existing relationships matter more than any new approach.
  • Its grants point to university education, specialty hospital care and arts & culture, but these themes are drawn from its grants rather than stated by the foundation, and no geographic focus is stated, so the locations in its grants (mainly New York, Massachusetts, Tennessee and Pennsylvania) should not be read as a rule on who may apply.
  • The filing gives no timing or deadlines, so any planning should rest on the invitation route rather than a fixed cycle.
