About Me

My background

My name is Jon Greenwich and I am a Certified Strength and Conditioning Specialist. I am a native of Northern, VA, a former collegiate athlete for the Univeristy of Maryland Terrapins, and currently the head strength and conditioning coach for The Catholic University football team in Washington, DC. I've been working with athletes of all levels for almost a decade now. With over 500 athletes trained successfully, ThinkFast Sport's leads the way in the Mid-Atlantic region for high quality sport-performance and fitness training.

My Philosophy

I believe that consistency is key. Any athlete at any level can make improvements to their body and increase their level of performance. If you have the will, we have the way.

My style

Positivity yields the best results. Most athletes need to learn how to love training. That's what it takes to improve and where I can make the greatest impact. My ultimate goal is to have my athletes "want" to train. Then the rest takes care of itself.
