Preschool gymnastics?

We moved here not too long ago; I'm living in Argyle but will move to Grand Prairie this summer. I'm looking for a gymnastics class for my 2 1/2 year old. She's been in gymnastics in Boston since she was 18 months. There's a "mobile gymnastics studio" coming into her preschool once a week, but she's not doing the things I know she's capable of; I think she may be bored, so I'm looking for a real gym - a full gymnastics facility, with age-appropriate programs for the little ones, but also more advanced classes that she could grow into. Basically, she's used to having a gym with just gymnastics, not her preschool classroom toys as a distraction, and she's used to full-size equipment, not too-wide balance beams and only a mini-bar.
To make it harder, if there is somewhere between Argyle and Grand Prairie, that would be perfect... or a chain that I could switch from one location to another when we move.
Thanks,
