I live in Roswell and my 4 year old attends Tolbert Yilmaz School of Dance off of Hwy 9 (near Holcomb Bridge intersection). She loves it and this is her second year of tap/ballet. Another option is the Roswell Rec's dance classes. They aren't as "technique" oriented for that age group, but they are fun (I have a number of friends who have daughters enrolled there as well). Both have end of the year recitals at the performing arts center. There is also a small dance studio near Mangia Pizza (Crabapple area). I don't know the name, but have heard several people talk about it. Hope that helps.
