Who the money went to
Grants this organization reported paying: Schedule I Part II of the Form 990, or the grants-paid list on the 990-PF. Open a year for every recipient. Recipients link to their own page when the grant names an EIN we have (990-PF grants list no EIN, so those link only on an exact, unique name and state). Grants to individuals are counted; their names are not shown.
2024 · 46 grants to organizations · $19.0M
2023 · 64 grants to organizations · $23.8M
2022 · 56 grants to organizations · $19.7M
2021 · 11 grants to organizations · $4.5M
Listed grants add up to $4,475,000; the return's “grants paid” expense line says $6,094,062. Returns can differ here (grants paid vs. accrued, items listed elsewhere); check the filing.
2020 · 8 grants to organizations · $554K
2019 · 24 grants to organizations · $2.2M
Listed grants add up to $2,196,370; the return's “grants paid” expense line says $2,234,174. Returns can differ here (grants paid vs. accrued, items listed elsewhere); check the filing.

Who gave
Contributors listed on Schedule B of the Form 990-PF: name, city and state as filed (street addresses are not shown), with total and noncash contributions for the year. A link to an organization's page is tagged Fuzzy with its name-similarity score (0 to 1) when it rests on name and state; Schedule B lists no EIN, so no link here is an exact identifier match.
