We attended USA gymnastics for several years. Overall my kids had a great experience. There's a lot of changing with teachers in the boys youth program, so I wished there had been more consistency. The place is almost always crazy busy, but it is a well oiled machine! And then the other drawback is the cost. Perhaps all tumbling/gymnastics classes run at about 20 dollars an hour? I work in the dance world and classes are almost half that cost.
