Each tax year counts once: when a return was amended, only the latest return for that period is used below (superseded returns stay listed, greyed, under Finances).

People paid by the organization

None of the 4 people listed on these returns reported compensation from the organization. They are listed below.

Officers and directors, no compensation reported

4 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.

People by year

Highest-paid independent contractors

No independent contractors reported.

Who gave

Contributor names are not public for this form type.

Public charities filing Form 990 or 990-EZ report large donors on Schedule B, but the IRS withholds their names and addresses from public copies. Private foundations (990-PF) are different: their contributors are public.

Finances

Newest first. Each filing: its name on one row, its figures on the row beneath. Greyed filings are superseded by a later return for the same period and are left out everywhere else on this page.

Funders of this organization

Not reported: no grants to this organization appear in the filings we have (tax years 2010 to 2025).

Similar organizations

Ranked without any AI: same NTEE code first, then the same NTEE group; then revenue within 2x, 5x or 10x; then the same state; then similar name and mission text. Same state only · More (100)

Who funds organizations like this

Grantors that funded the 100 most similar organizations. Ranked by total given to them. Foundations (990-PF) and donor-advised fund sponsors only. Same matching as Funders above (by EIN, or by name for foundations).

Where the money went

Every expense line on each return, biggest first: Form 990 Part IX (with its program, management and fundraising columns), 990-EZ Part I, or 990-PF Part I. 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.
