About EverProven

Not Ready for A Full-Time Commitment?



Proven Performance Center, home of EverProven CrossFit is a group fitness based facility offering personal training, group fitness, nutrition coaching, and sports performance training. We have a full coaching staff prepared to differentiate instruction based on any fitness level or ability.  

We’ve used our same routines for elderly individuals with heart disease, full-time parents, military, police officers, firefighters, people fighting obesity, and those just looking for something different. Our classes are 60-75 minutes in length and are comprised of a warm-up, mobility work, skill work, strength building, and metabolic conditioning (metcon). All movements and workouts can be modified to meet you where you are and guide you to the road to a healthier, stronger you.

“Great gym! Very welcoming members, very friendly coach, great coaching and workout. Loved the space too! Big, clean and well organized.”

“Everything about EverProven has been top notch since day 1”

Like many of the original CrossFit Boxes, EverProven CrossFit started with a small group of friends, in a garage, with cobbled together equipment.

Nearly a decade ago, Matt, Katie, Christian, and a few friends began training as CrossFit L-1 Coaches in Matt and Katie’s garage. They fostered a large group of friends that wanted to train with them, so they opened the box in an dusty old space in the mills. Years later they grew out of it into the best-in-class facility you know today as Proven Performance Center.

Make a Change

You deserve that life you dream of.

Whether those dreams are finishing a 5k, or beating your time in that 5k, making the CrossFit Games, making the Olypmics, or simply just being fit enough to enjoy those long hikes with your friends and family without feeling like you missed out. We can help you achieve your goals, and take your life to that next evolutionary step.

I’m learning new things every class about warming up, positioning, technique and myself. It’s been an amazing community to be apart of and some great friendships have already been made.

I would recommend it because you always have a coach to help you with anything!! You walk in a stranger, you leave as family… Amazing people , when you need something, the community is there for you. Plus you get the best workouts of your life. It challenges me everyday. You never get bored. I could go on and on why I recommend EverProven. They are just amazing!
