We have been sending our 3 year old daughter to the little ninjas preschool obstacle course class at ultimate ninjas and couldn’t be happier. I was worried about sending her since she’s on the smaller side, but all the coaches are very patient and helpful. Coach Dana and Coach Mike create an incredibly motivating and encouraging environment, challenging the kids in a supportive way that allows them to become stronger and more confident while also having tons of fun. My daughter tends to fade in her enthusiasm for new activities but she can’t wait to go to “ninja class” each week.
