The website is unfortunately only partially in english. The dance school appears however to be quite active with 80 students (information from the school).
The school has provided us with the following information:
ISTA Irish Dancing School (Poland) provides regular Irish dancing classes or beginners through advanced dancers in Warsaw, Cracow and other Polish cities as well as verious workshops in different techniques and levels of Irish dancing throughout Poland. We invite Irish teachers and renown dancers such as Catherine Gallagher (Riverdance) and James Devine (Gaelforce Dance) for workshops and summers schools.
Apart from teaching we organize some of the biggest Irish dancing events in Poland, such as two huge anniversary concerts for 10 Years of Irish Dancing in Poland (December 2003) and Celtic Summer - Summer School and open Irish dancing Festival (July 2004).
