I have been kickboxing at Cornerstone for years now and love it!! I had kickboxed years ago at a couple of other local gyms and didn't have very good experiences at either, so I gave up for a while and looked for other ways to burn the calories. After attending a kids karate party at Cornerstone several years back and noticing the heavy bags, I decided to give kickboxing another go and I'm so happy I did. All of the teachers are excellent, the pricing is extremely competitive, the class schedule is awesome for a busy working mom and I burn just as many calories as when I run, and have a lot more fun doing it! :) read more

Cornerstone is awesome. We found them back in 2014 by convenience due to their location and have been going since. We started our daughter and 2 months later, my wife and I joined their Adult Tang Soo Do program. They have an excellent program for the kids and run "parents classes" at the same time - What a great way to get involved rather than just sitting and watching the kids. We are testing for our first black belt in the spring and our daughter isn't far behind. If you are looking for a fantastic traditional martial arts program, be it Tang Soo Do or Muay Thai, I highly recommend Cornerstone. read more

I give this a 5 star rating because it had everything that I wanted: great instructors, structure, teaching of fundamentals, most importantly, family atmosphere! Master Kloss is all about family and it shows! Very patient with students, young and old! From novice to black belt and beyond, the only martial arts teacher I've had as a past student, and if my family and I had to return, this is the place to be! read more
