Couldn’t be more happy to have my son go to Coach Deckers Mat Monkey class! It’s the perfect Intro to karate. He teaches independence and respect. My 5 year old has learned so much!Posted on Google![]()
Nicole ShahaTrustindex verifies that the original source of the review is Google.
We have truly enjoyed the Mat Monkeys Judo class for our son. Coach Decker is awesome and we can tell he truly cares about his students. Our son started at age 4 and has grown a lot in terms of the skills in the class but more importantly being respectful to leaders, listening, participating with other students, and trying new things. We just finished our first year of class and hope to continue.Posted on Google![]()
Thomas CTrustindex verifies that the original source of the review is Google.
Coach Decker has mastered combining fun with discipline. My children look forward to their classes twice a week. They are proficiently learning basic judo in a short amount of time, but more importantly, respect and discipline are also being instilled; all in a fun and supportive environment.Posted on Google![]()

Lindsey OttTrustindex verifies that the original source of the review is Google.
I’ve been going to kickboxing at Coach Decker’s twice a week for over a year and a half and it’s truly 5 stars! The gym isn’t intimidating and coach makes you feel right at home and welcomes you from day one. It’s fun and a great workout! We stretch, warm up, shadow box, strength train and hit pads with partners. You don’t have to know a lick about kicboxing, coach teaches the 10 main moves and explains them for newbies to understand. I enjoy breaking up my workout routine with kicboxing twice a week and stumbled into the right place to do so!
