How this page is made

Each grant comes from a foundation's IRS Form 990-PF and was linked to this EIN only when this was the single organization in the IRS Business Master File with that name in that state. Grants written under a different spelling, or where several organizations share the name, are not counted here, so the real totals can be higher. Government grants and gifts from individuals do not appear on these returns.

• IRS Business Master File record updated Nov 9, 2026; listed in Publication 78 (eligible for deductible contributions)

Facts on this page come from the foundation's own IRS Form 990-PF filings as published by the IRS. Grantvello does not know whether a foundation is accepting proposals right now: a past grant is not an open opportunity. Always confirm current guidelines with the funder before applying.
