My daughter has been attending Tippy Toes ballet classes for the past 4 years, since she was 3. She has always loved her ballet classes and last year she achieved a Distinction on her Primary ballet exam. We are very happy with the admin of the company too as they have always offered alternative days if my daughter had to miss one of her classes.
Overall I would highly recommend them both for the high level of ballet they teach and the fun way the classes are structured.
