After last autumn Roger Long has joined as a coach to us ( and will complete all coach training in the next few years ), we can announce a further strengthening in our Academy.
Greta Arn is used from August 2013 our bases Bad Ragaz , Klosters and Davos. She has just finished her professional career and is currently still at position 174 in the world rankings . Two years ago she reached the best ranking as number 40! She has also successfully completed the B-Instructor Training in Germany .*
We are looking forward to this cooperation and are confident that our girls and guys will get a lot more valuable tips in the training.
