G.T. Bynum currently serves as the vice president of community and government affairs in the Saint Francis Health System. He served on the Tulsa City Council (2008–16) and as mayor of Tulsa (2016–24). As mayor, Bynum guided Tulsa through its greatest public health crisis and major natural disasters while never losing an election, for office or in support of public improvements.

Bynum led the physical transformation of Tulsa–Zink Lake, Gilcrease Museum, the Gathering Place, and other major public projects while fostering a historic boom in private-sector investment ranging from Amazon to American Airlines. He initiated the search for unmarked graves of 1921 Tulsa Race Massacre victims, created the Tulsa Police Real Time Information Center, and paved more miles of road than any mayor in Tulsa history.

G.T. is married to Susan Bynum, Vice President of the University of Oklahoma–Tulsa. They are the proud parents of Robert and Annabel—the sixth generation of Bynums to call Tulsa home.
