Marshall was born and raised in Richmond, Virginia.  He began swimming at age six, and continued throughout high school.  He then began coaching as a teenager at a local YMCA where he fell in love with teaching and empowering young athletes.  As an undergraduate student at Virginia Tech, Marshall worked for five years as an assistant coach with the swimming and diving team.  There he coached ACC champions and record holders, NCAA All-Americans, and Olympians.  After graduation Marshall remained in Blacksburg to continue his efforts with Virginia Tech as an assistant coach.  He also assisted with the post-graduate group, Pinnacle Racing, led by Sergio Lopez.  This position allowed him to work with Olympic athletes from twelve different countries.

Marshall’s coaching philosophy balances intensity with empathy, competitiveness and togetherness.  His goal is to create well-rounded young adults that seek to support each other in positive ways, both in and out of the pool and help continue to build that culture at ATOM in all practice groups.  Marshall is excited to join the ATOM family and continue to build up our tradition of creating an environment where champions are inevitable.
