Across Green Country, from the Tulsa Zoo to ONEOK Field, education to health, assisting neighborhoods to assisting nonprofits, Tulsa Community Foundation (TCF) is making a difference in Eastern Oklahoma. TCF is truly this community’s foundation: a reflection of Tulsa’s overwhelming philanthropic spirit and concern for the lives and well-being of others. Tulsa Community Foundation is among the largest community foundations in the nation. This designation is due to the commitment donors, nonprofit agencies, professional advisors and community leaders have made to the foundation and its future.
