Hager served as chief financial officer for Trussville's Southern Comfort Conversions from 1998 to 2004, and held the same position with Montgomery's Kelly Aerospace until 2010. He was hired on the authority of Commissioner Bettye Fine Collins during an announced hiring freeze. Though the position was renamed, he was seen as a replacement for former finance director Steve Sayler, who resigned in September 2007.
Hager was also the winner, in 2009, of the $12,000 grand prize in a nationwide online contest sponsored by Dunkin Donuts to create a new specialty donut. His winning entry was "Toffee for Your Coffee", a glazed, sour cream cake donut topped with chopped Heath Bars. He and his wife, Angela, have three children.
