"My daughter has selective mutism which is an anxiety disorder since she started KidStrong with Coach Joseph her anxiety disorder has improved. I am happy that the coach has shown compassion and empathy to my child, she feels connected with him, and loves winning awards. I can’t wait for her to be able to show off her voice soon."

How is my party run? What is the schedule of the party?
Our coaches will check in all guests and ensure that a waiver has been completed. Once checked in, kids can join the coach on the blue floor for explore time. When the majority of the guests arrive (typically 5 minutes after party start time), or when the party parent is ready to begin, the coaches will begin the games on the blue floor. Blue floor games and activities will take about 70 minutes and the remaining party time will be for food/cake.
