gymnastics for Sierra

I'm planning to enroll Sierra by next month at Gymstrata , it was referred by a friend whose kids are currently enrolled there. she said her kids are doing gymnastics and really love it over there. she's also telling me if i wanted to enroll Sierra in a ballet class because she can also refer a great place. I'm planning to have Sierra enrolled at gymstrata for once a week so that she could have an outlet for her energy hahaha
