4 other organizations in the IRS Business Master File list the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

As listed in Part VII of the 2024 return, in the order the filer printed them. Each return names its own; this is not a roster the organization keeps with us.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

As filed, from the IRS e-Postcard file of 2 November 2026. The IRS publishes only each organization's most recent postcard, so earlier years are not shown. A 990-N carries no financial detail. The postcard also gives the principal officer's address, which is not shown here.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

No itemized grant names this organization as a recipient. Only grants over $5,000 are itemized, and only by filers of the full Form 990.
