Gary M. Mitchell, a Prairie Band Potawatomi Nation tribal leader and former PBPN Gaming Commission chairman, died Friday in Topeka, the tribe said in a news release.

Gary Mitchell, 63.

Mitchell, 63, graduated with a bachelor’s degree in political science from Washburn University and a master’s degree in history from Baker University, the release said. He served the tribal council for 18 years as treasurer, vice chairman and eventually chairman.

A lifelong reservation resident, Mitchell was an influential figure with Tribal-State gaming legislature in the 90s, the release said. He was also active in every phase of bringing gaming to the tribe and overseeing the casino’s design.

“He was a good man and a well-respected member of the community,” said PBPN Tribal Council Chairperson Liana Onnen. “He understood the importance of preserving the culture, traditions and history of the Prairie Band Potawatomi people in a deeply profound way.”
