O’Brien was born and raised in Glen Ellyn, Illinois and originally did not think of the military as the correct career path for himself. Now, with over 22 years of service, O’Brien has spent much of his time in the military carving new career paths, leading Marines and Sailors, and building a family. (U.S. Marine Corps photo by Cpl.
