In leading the Mission Assurance organization, he ensured that the quality of Pantex and Y-12 production activities met requirements of federal program and design agency customers, which provides certifiable confidence in the nuclear stockpile. Other daily responsibilities included providing subject matter expertise for all readiness activities, nuclear and explosives safety, and coordinating with the Department of Energy Office of Enforcement Coordination.
