Bryan Arnold joined the Wittenberg men's lacrosse program as a graduate assistant coach in 2008 after a three-year career as a defensive standout for the Tigers. He helped the team to a 6-6 record in his first year as the defensive coordinator, including a 2-3 mark in the NCAC, which was good for fourth place - Wittenberg's best conference finish in four years.

Arnold received three All-North Coast Athletic Conference awards in his Wittenberg playing career, including honorable mention in 2005 and second-team in 2006 and 2007. A two-year team captain and the team's most valuable defensive player in 2007, Arnold accumulated 88 ground balls in his three seasons in the Red & White. He graduated from Wittenberg in 2007 with a bachelor's in history.

A native of Columbus, Ohio, and a graduate of Dublin Scioto High School, Arnold currently resides in Springfield and works as a substitute teacher in the nearby Mechanicsburg School District.
