Testimonials For ISM

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.

Summiting Mont Blanc was an important milestone for me which I am grateful to all at ISM. Particularly Terry, who is the ultimate professional never compromising on safety. Max is a pure gem with wonderful guidance and outstanding people skills in abundance.Altogether a brilliant week!

Mont Blanc Ascent

Terry was a wonderful guide and made everything fun, laid-back and an overall good experience. I would be happy to ski or climb with him again. All the logistics in Leysin and in Italy went smoothly. A really nice time.
