About EverProven

Not Ready for A Full-Time Commitment?


Our Vision

EverProven started with a simple vision: to create the premier fitness community in Dover. We are a full-service strength and conditioning facility dedicated to educating, entertaining and inspiring all who we come in contact with. We strive to help individuals from all backgrounds and abilities become a better version of themselves by providing excellent service, compassion, care and unparalleled coaching in a fun and welcoming atmosphere. 

Our Mission

At EverProven, our mission is to make the world a better place by helping all individuals who pass through our doors live a better overall quality of life through fitness.  Our goal is to forge hardwearing relationships with those we serve. We strive to educate, entertain and inspire inside and outside our community and always do the right thing. We are committed to providing excellent customer service without ever losing focus on helping individuals achieve balance and success inside and outside of the gym.

 Our Core Values

Our core values guide our day-to-day actions, and provide the foundation of what we want EverProven to stand for:

Community: We are a community above anything else. Every decision we make here is for our members. We want this to be a place you can not only reach your fitness goals but also make lifelong friends. Though we are all working toward different goals, we are a group of like-minded individuals and athletes cheering each other on along the way. Support each other! If any of our members or coaches are ever in need, we will come together to lend a helping hand.

Commitment: We commit ourselves to the pursuit of fitness for individuals on any level. We are committed to having a better understanding of the priorities, goals and passions of our clients. Through this understanding we strive to constantly create services and offerings to support the personal growth of our members.

Spirit: We believe that fitness happens on many levels. We strive for a community that supports and fosters physical, emotional, and spiritual harmony.

Integrity: We act with integrity and honesty, and focus on putting ourselves in the shoes of others. We will always do the right thing, even when no one is looking.

Perseverance: We are dedicated to achieving the goals of our clients. Our success depends entirely on helping our clients work towards achieving their goals.

Growth: We strive to constantly expand our knowledge base and educate our clients with the knowledge we acquire. Our community places their trust in us, and we will invest our time and energy to ensure that trust is repaid with the best instruction, guidance and knowledge we can acquire.

Good Citizenship: We are good citizens in the community in and out of the gym and strive to make a positive impact on both.

Give Joy: Laugh. Be grateful, positive and hospitable. We strive to make people feel good.


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.
