The Lowell S & Betty L Dunn Family Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- This foundation makes grants only to organisations it has preselected and does not accept unsolicited requests, so a charity that has not been invited to apply should not send it a proposal; the filing does not describe how organisations are preselected.
- Its typical grants fall between $5,000 and $150,000, with about 8 in 10 of its 100 grants to organisations in that band, half at $25,000 or less and a median of $25,000, so a modest request of around that size fits its usual pattern, though its largest grant was $450,000.
- Most of its grant dollars go to organisations it has funded before: 64% of its grant dollars in its most recent filing went to organisations it had also funded in one of its two earlier filings, so relationships appear to matter and a first approach is unlikely to be routine.
- No geographic focus is stated; its filings show grants mainly in Florida, Tennessee and Georgia, but that is only a pattern in its giving.
- Its recorded giving covers hospitals and medical research, community relief and human services, animal welfare, and children and young people, so a case in one of those areas is the closest match to its past grants.
