Mart Green

Green pledged a $70 million gift in November 2007 to Oral Roberts University (ORU), enough to retire much of the university's debt, on the condition that the university show good governance. Of the $70 million that was pledged, he gave an immediate $8 million during the November 2007 board meeting. The remaining balance of the $70 million was given later.

Upon an agreement with the University, Green became the new Chairman of the Board at ORU and a majority of the Board of Trustees was replaced.

In January 2009, Green and his family gave an additional gift of $10 million to ORU for campus renovations. In January 2009, Green also announced the ORU Board of Trustees selection of Mark Rutland as ORU President. In December 2010, ORU announced that the Green family would make another $10 million gift in 2011, to be used for renovations and technology improvements. The gift raised the Greens' total donations to ORU to $110 million.

His father David Green is founder and CEO of the arts and crafts retailer Hobby Lobby, and Mart sits on the board of directors. His younger brother Steve Green is the President of Hobby Lobby, patron of the Green Collection and founder of the Museum of the Bible in Washington, D.C., which opened in November 2017.

Green has been married for more than 30 years to his wife, Diana. The couple has four now adult children: Brent, Amy, Tyler, and Scott, and have four grandchildren.
