The Simone Charitable Foundation Inc., a private foundation headquartered at 8800 N Gainey Center Dr, Suite 160, in Scottsdale, distributed $4,839,761 in grants across 12 awards in tax year 2023, according to IRS Form 990 data published by ProPublica Nonprofit Explorer.
The foundation reported TY2023 revenue of $6,599,284 against expenses of $8,876,064, a gap of roughly $2.3 million. That follows a TY2022 shortfall of approximately $3.3 million, when expenses of $9,200,673 exceeded revenue of $5,885,657. In TY2021, expenses of $8,167,481 also outpaced revenue of $7,192,727. The cumulative effect is visible in the asset line: the foundation held $116,213,813 in assets at the close of TY2021; by TY2023 that figure had declined to $109,446,188.
Officer compensation was reported as $0 in each of the three years on file, consistent with the structure of a private foundation whose principals are not salaried employees.
Grant-making focuses on philanthropy, human services, and health care, with awards concentrated in Arizona, New York, and Illinois, according to Instrumentl's 990 report on the foundation. The typical grant range runs from $45,000 to $900,000 per award.
Mark Grayson serves as President, Curt Christensen as Treasurer, and James Geaves as Director, per the same filing data. The foundation is registered as a 501(c)(3) with EIN 82-3971316 and is classified as a private foundation, a designation that makes it ineligible for Charity Navigator star ratings, as noted on the foundation's Charity Navigator profile.
Who controls the foundation's grant decisions?
Public 990 filings identify Mark Grayson as President, Curt Christensen as Treasurer, and James Geaves as Director. The filings do not disclose a donor or founding family name, and the principals behind the foundation's name are not identified in available public records.
The foundation's TY2024 990, which would reflect the most recent $115.2 million asset figure and $4,752,444 in grants across 12 awards reported by Instrumentl, has not yet appeared in the ProPublica database; private foundations typically file on a calendar-year basis with extensions running into the following year.
