Craig DeCollibus
Coach
Coach Bio
Craig DeCollibus
Coach
“[Coaching is] a relationship built on trust that I’m knowledgeable in what I’m teaching and the members are returning the favor by learning and giving me (and themselves) all out effort every time they are in the gym. Great relationships like these result in progress towards their goals 100% of the time.”
Craig is self-admittedly extremely competitive and in finding CrossFit, he found the competitive outlet that he had been missing since his lacrosse days. He was captain of his D1 lacrosse team at Siena College, then transitioned to endurance and obstacle races in pursuit of competition. Finding CrossFit Westchester truly fulfilled and fueled his desire to compete, and even led him to change career paths when he realized CrossFit is much more than exercising for time. His goal as a coach is to help people live healthier lives through functional fitness.
