Matthew Grund

Endurance Coach

I became CrossFit L-1 certified in 2015 and also hope to earn my L-2 certification soon. My passion is nutrition, especially how it can impact performance both in and out of the gym. I am the office manager for a local physical therapy clinic, Athletes' Potential, which allows me to see and learn first-hand valuable movement and mobility based exercises to apply to my coaching. I am currently pursuing a nutrition certification through Precision Nutrition, which will allow me to apply my passion for nutrition into the ability to help people reach their performance and aesthetics goals, as well as a healthy and realistic relationship with food. I got married to our endurance coach, Matthew, in March of 2018, and we live in Marietta with our two cats and step-son, Tyler. And, since I'm sure everyone wants to know... my favorite WOD is Diane.
