Don't wait for prom season, with Grandiosa you can make dancing part of your everyday life. We hold ballroom dance classes several times a week. Need to brush up on your dance steps? Then take advantage of our open individual dance lessons for beginners.

We believe that free time is meaningful - when it is filled with movement, creation, discovery and joy. That's why we offer courses for children and adults that develop the body and mind. At Ostrák we dance, exercise, paint, learn and relax.

We are a dance school dedicated to educating children from young age (four years old) to adult dancers. We organize performances, competitions, workshops or dance camps.
