John S. Dunn Foundation
At a glance
Key takeaways
- This is a good fit only for charitable organisations serving the greater Houston area, with work in healthcare education (including nursing programmes), healthcare clinics for the underserved, mental health programmes or medical research, or nursing scholarships and medical research endowments and chairs; it does not make multiyear grants, though it encourages matching grants and collaboration.
- A realistic request would sit within its typical grant range of $15,000 to $200,000, with the median grant at $50,000, though amounts have gone as high as $3,000,000 and its total paid in a recent filing year was $5,107,452.
- Applications are accepted on a rolling basis through an online form asking for the nonprofit's name and address, its IRS determination letter and the amount requested for the project or programme, so there is no fixed deadline to work to.
- With just over half of its grant dollars going to organisations it had also funded in the two previous filing years, the Foundation looks relationship-led, so building a track record with it may help over time.
- It will not fund businesses or individuals, capital campaigns, construction and/or furnishings, advocacy, other foundations that re-grant to third parties, scholarships paid directly to individuals, Type III Section 509(a)(3) supporting organizations, other private foundations, or organisations that do not meet Section 501(c)(3) criteria or are not non-profit, tax-exempt organisations.
