Sad news yes, but in this time of parents and children having so many options for activity not a surprise. Plus, Danville Ballet mainly offered classes of a "balletic" nature. Most schools that are surviving offer tap, jazz and hip hop in addition to a ballet division with adult ballet, yoga and pilates mat classes rounding things out.
My daughter has studied at two schools in the bay area and both offered a wide curriculmn.
I wonder if it is even possible to operate a dance school sucessfully on ballet only?
