My son has been going to Peewee classes (3-5 year olds) for 4 months now and he has grown considerably in confidence and strength. Sensei Bob and the other staff are amazing with the kids - very patient, encouraging, and consistent.
The class is a nice balance of helping the children burn off their energy and teaching them something new. The instructors love rewarding the kids who work hard with stickers and patches, but I think the kids really appreciate the honest cheering from the instructors and the double high fives.
