Common questions
Which foundations give to nonprofits in Riverton, Wyoming?
First Interstate Bancsystem Foundation Inc, The Niner Foundation Inc C/O Pamela S Niner, Helen Petersdorf Educational Trust, Oletha C Likins and Loren E Likins Perpetual Memorial Trust Fund, Santa Fe Natural Tobacco Company Foundation and 22 others reported grants to Riverton organizations on their latest Form 990-PF.
How do I approach a foundation that doesn't accept applications?
A foundation that checks "contributes only to preselected organizations" on its 990-PF won't review a cold proposal. Look at who it funds, find a shared board member, grantee or advisor, and ask for an introduction. Foundations that accept applications usually list a contact and deadlines in Part XV; we show that text on each foundation's page.
Is this list complete?
No. It covers private foundations (Form 990-PF filers) whose latest electronic return lists at least one grant to an organization in Riverton. Community foundations and corporate giving programs file different forms and are not included yet.
