What People Are Saying

Wonderful Community

“I’ve been a member at Roots for over 5 years now and all I can say is Nicole and Eric run a wonderful box and community.  The coaching staff are all highly qualified and great at what they do. They prioritize safety and are clearly passionate about the member experience. I highly recommend CrossFit Roots to anyone interested in prioritizing health and joining a welcoming community.”

Tons of Class Options

“Fantastic, spacious gym with dedicated coaches and a great community of athletes who are always encouraging. Tons of classes every day so you can catch a workout regardless of your schedule. I went from 15 years on the couch to regular workouts with far greater ease than I ever could have guessed, and I credit the people just as much as the CrossFit system. Thanks, Roots!”

~ Tyler E.

The Big Comeback

“I have been going to Roots for a few years and truly appreciate the gym and the staff. Roots’ staff ensures a solid warmup, proper technique is used, and scaling is appropriate for the design and intent of the workout. I had a total knee replacement about a year ago and I owe a smooth and relatively easy recovery to CrossFit and the knowledgeable staff at Roots. I got back to the gym ASAP per my doctor and the coaches were thoughtful of my limitations and my post-surgical goals.”
