Denise and Michael Kellen Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- This foundation does not accept unsolicited requests, so any approach needs to come through an existing connection rather than a cold application.
- No geographic focus is stated, though the filings show grants mainly in New York and Massachusetts.
- A realistic request would fall within the $10,000 to $1,250,000 range seen in the filings, with about 8 in 10 grants falling there and a median grant of $125,000; the largest grant was about $10,000,000, so very large sums are possible but not typical.
- The funding spans universities and research institutions, hospitals and medical centres, arts and cultural organisations, a library, religious organisations and animal-focused charities, all recorded simply as general fund support, so there is no narrower stated field to match against.
- With 72% of grant dollars going to organisations also funded in the two prior filings, this looks like a relationship-led funder where repeat giving is strong, so new applicants should expect it to be competitive without an existing link.

What they fund
Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.
Priority Areas
The filings show grants to a range of organisations rather than a single kind of recipient. They include universities and research institutions, hospitals and medical centres, alongside arts and cultural organisations, a library, religious organisations and animal-focused charities. Every grant purpose in the filings is recorded as general fund, so the record does not state a narrower activity or a declared field of focus.

Overall, the evidence describes broad organisational support, with grants recorded for institutions and charities across education, health, culture, faith and animal-related work.
