All of the instructors are awesome here! Grand Master Matt and Master Kay are awesome at stepping in and helping out if your child is having behavioral issues as well. They're also awesome if your child has special needs. They're … More understanding and helpful and the first people that didn't make us feel bad for being "different". They've been helpful to Micah and our family and I'm grateful we have Keystone X in our lives.

I known Matt Trimmer since his other gym and recently had gotten back into kickboxing with him here. I love the workouts that he puts together for the class, walking around and spending time on each individual and their needs. This gym … More is very friendly and I have met some pretty incredible supportive people in my class. They have helped me keep motivated and with each class that I complete, I just want more and more. I also love the 24/4 hour gym access, where you can work on bettering yourself on your own time. I love it here!

Believe me when I say All ages and abilities are welcome!! Coach Trimmer is highly … More experienced, dedicated and an excellent trainer. He’s committed to his students and their goals and often becomes like family. This is a safe place for your kids and family to invest your time and money for your health and to learn new skills.
