Officers and directors, no compensation reported

2 people listed on the returns with $0 (or no amount) in every compensation column: current people first. Hours are as filed on the latest return each person appears on.

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 · 14 grants to organizations · $2.8M
2023 · 15 grants to organizations · $2.6M
2022 · 14 grants to organizations · $1.8M
2021 · 18 grants to organizations · $1.7M
2020 · 17 grants to organizations · $1.5M
2019 · 16 grants to organizations · $1.2M
2018 · 12 grants to organizations · $885K · 5 grants to individuals · $139K

Negative amounts are returned or refunded grants; they are listed last and left out of the totals of grants paid.

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.

Event marks lines the organization itself describes as events. “Events” in each summary adds those lines, conferences and meetings, and the direct costs of fundraising events. Unusual is not the same as improper. Many of these patterns have ordinary explanations. Check the filing.
