Kevin has been involved in competitive athletics his entire life. You could almost say it defines him. It didn’t matter if it was a game of Monopoly, a foot race, the much anticipated gallon milk chug challenge, or a collegiate basketball game; he wants to win every time. That fire came to an end when his basketball career was over, and like many, he jumped around trying to find something to fill that void. Finally, he stumbled onto CrossFit in October 2012, and that void was filled.
