He started CrossFit in 2007 when a friend found some workouts on the Internet, and has been dedicated to CrossFit since then – even while training for the City of Oaks Marathon which he ran in 2016.

Eric’s desire as a coach is to see people do more than they thought possible. He likes accountability, wall ball shots, rucking, firearms, and beer. He dislikes time caps, dairy, and when people don’t turn on their headlights in the rain.
