Tulsa Community Foundation

The Tulsa Community Foundation (TCF) is one of the largest community foundations in the United States. Headquartered in Tulsa, Oklahoma, as of January 2011 it was reported to have approximately four billion dollars in assets, and to have donated more than $580 million to local charities and government projects.
Tulsa Community Foundation is a tax-exempt, public charity organized in 1998. It was founded by Tulsa oilman, banker, and philanthropist George Kaiser, who felt that Tulsa's historical dependence on unorganized private giving from its wealthy families was no longer effective.
