Testimonials For ISM

Thanks for organising an excellent week. The course format, accommodation and set up was perfect. The guide was outstanding and gave us a full week of constructive tuition. I was able to put his training into practice the following week when I met up with a friend and did the Cosmiques Arrete.

Thank you very much for an enjoyable and inspiring week in the Alps, and for your patience and good humour throughout. You have a completely satisfied customer and I hope to join another ISM course sometime in the future.

​Hi Eira! It is Maite from Spain again! Just a message to tell you that I spent a wonderful week and that both guides (Paolo and Christian) were superb.
