Coach Decker is knowledgeable and patient, breaking down judo techniques in a way that is easy for the kids to understand. My son is learning valuable skills in self-defense and discipline, all while having a blast. He looks forward to every class. Highly recommend the Jr. Judo class!

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.

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.

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!
