- Assistant to the Coaches
Everleigh is the youngest member of our team and began coaching at just 3 weeks of age. You will often find her riding in a backpack carrier on her mom (Coach Marissa) during classes or crawling around the mats and drilling during open mat. She helps to demonstrate movements and coaches at tournaments. While she hasn't earned any belt levels yet, she will surely let you know what she thinks of your technical abilities by the look on her face. When Everleigh is not managing the gym she enjoys spending time with her "doggie" and "cats".
