This article is about the businessman. For the singer/songwriter, see Michael Warren.
Warren was an attorney with Bradley, Arant, Rose & White until 1983 when he left to become general counsel for Alagasco. A year later he was named president of Alagasco, and then in 1997 became CEO of its parent corporation, Energen, where he also served as chairman of the board.
He announced his retirement in 2007, in keeping with the tradition of Energen executives retiring at age 60. Though he initially turned down an invitation to pursue the CEO position at Children's Hospital, he agreed to be considered after the board interviewed several other candidates and returned to him. He took over from Jim Dearth, who retired.
