At first I thought just another karate school. But that quickly changed as my kids loved it, the instructors welcomed us all with open arms as one of their family. Always there for you. Our kids have learned so much and we love the way they answer yes sir, yes mam at home as well. They look forward to class everyday and are upset when they miss a class. Action karate Hamilton is much more then any other karate school with all the extra interactions, and events they hold. If your thinking of joining a karate school pls . Try action karate Hamilton you won't be disappointed.
