Mark Rosen, the head volleyball coach at the University of Michigan, gives a school coin to Marine Corps Commandant Gen. Robert B. Neller during an evening parade reception as part of Marine Corps Recruiting Command’s 2018 Coaches Workshop at Marine Corps Barracks in Washington, D.C., May 18, 2018. The annual workshop educates approximately 50 high school and collegiate coaches from across the nation about Marine Corps leadership skills and programs that they can share with their student-athletes. Rosen is a member of the American Volleyball Coaches Association, an organization that educates volleyball coaches, recognizes elite players and coaches and promotes volleyball competitions and networking opportunities. The Marine Corps partners with AVCA to inform and inspire coaches through exposure to Marine Corps-style leadership, creating brand advocates among the organization’s key influencers.
