For Sean Johnston, ADS’ National Account Manager for State and Local accounts, being a part of a larger purpose has always been important to him. Joining the United States Marine Corps was a natural choice for him and he counts the opportunity to service his country as one of the greatest honors and accomplishments of his life. Sean served in the Marine Corps Reserves for eight years, from 2006 until he was honorably discharged as an E-5 Sergeant in 2013.
Sean held multiple billets throughout his military career, with his last billet being 3rd Squad Team Leader for the MWSS 472 MP Squadron. He also served in Iraq during Operation Iraqi Freedom in 2009 providing convoy security for high value cargo and was also involved in Quick Response Force missions. A career highlight for Sean was that he spent 3 weeks in Ayacucho, Peru where he provided security for joint task force humanitarian efforts to build local schools and hospitals in cooperation with the U.S. Air Force and U.S. Navy.
Sean’s time in the Marines taught him the value of hard work in achieving what he wanted, and to keep his eyes on the mission no matter how difficult the obstacles or challenges he faced. The lessons he learned in the Marines about integrity and how to be honest and truthful in everything he did shaped Sean into an exceptional leader who is completely committed to taking care of his people, always keeping their best interests in mind.
