Crosby reunited with his former college coach Jason Childs in 2010-11 to help Mercer University field its inaugural men's lacrosse team.

Crosby spent the 2010 season as the head lacrosse coach at Mauldin High School in Greenville, S.C. He led the Mavericks to the 2010 playoffs.

Crosby is a 2008 graduate of Presbyterian College in Clinton, S.C., where he joined Childs in founding the Blue Hose’s men’s lacrosse program in 2006.  Crosby had 24 career starts at PC as a midfielder and was a team captain, while also setting single game records for face-offs won and face-off percentage. As a senior, he had had the honor of being the recipient - and namesake for - Presbyterian’s inaugural "Charles Walton Crosby Unsung Hero Award” in recognition for unselfish play and contributions to the team’s success.

For the Bears, Crosby will work within every aspect of the day-to-day operations of Mercer’s lacrosse program. On the field, he will also work closely with the offense, both individually and collectively, while heading up the personal development efforts.

Crosby is married to the former Shannon Strodel (also PC Graduate and lacrosse player). The couple resides in Macon.
