The last review is an unfair one and probably done by a rival dance company.
I have attended classes at every dance company in Schuylkill County with my daughter to try to find one that was right for us. Dalinda's was probably one of the better ones. The instructors work very hard with the students on technique and terminology, which none of the others bothered with. This is a good place if you want your child to be a serious dancer and you don't want to drive out of the area.
We ultimately chose a studio in Hamburg because they offered everything we were looking for, but if we had to choose one in Schuylkill County, it would be this one.
