Last year, a nationwide security industry publication named Corey Hendrix one of 20 leading security integrators under age 40 in the United States. In April, Hendrix, 33, accepted the role of president of FEMAC Security Solutions, a Bulloch County-based company with a three-state reach that has served more than 300 banks, as well as commercial clients as large as Georgia Power. His parents own the company, and Hendrix first worked there while a senior at Southeast Bulloch High School.
