founders of the hille foundation

Jo Bob and Mary Ann Hille founded the Hille Foundation in 1997. It was a natural outgrowth of the spirit of giving in which they had been raised and of the basic Christian principle of lending a hand where needed. Feeling a deep loyalty, additionally, to the people and state of Oklahoma where they both had grown up, they set up the Hille foundation to focus on benefiting those closest at hand, hoping to extend to others the opportunities that had been generously given to them.
