My boyfriends son has been coming here for a little bit over a year now, and he loves it. Sensei Bob is a great mentor. You can tell that he loves his students and wants them to succeed. He is the only man I know that has that much patience with a dojo full of kids from ages ranging from 3-10. I will say that his class of maybe 15-20 kids, they all listen and pay attention to him. The students all participate and if they feel a little discouraged Sensei Bob is right there trying to boost their confidence.
You can sit in the lobby and watch your kid learn some karate moves, there is a open glass window where you can watch. You can also sit in the dojo and watch. Its up to you.
I'd recommend taking your child here if you are interested Sensei Bob is the one to go to. You kid will love the learning and experience.
