Try Champion Kids or Roswell Rec. I live in East Cobb too and the Roswell Rec classes are very convenient. My boys have both taken gymnastics when they were toddlers through Roswell Rec and loved it.
If you have a YMCA around, you may want to look there. My DDs have taken a combo gymnastics/ballet class (30 minutes of each) at the Decatur YMCA and have really enjoyed it.
