Testimonials For ISM

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.

KL (2017)

Our three guides were all excellent: Thomas, Phil and Paulo. I can't speak highly enough of them. They were all good company and superb climbers, and patient with us all.

Donald Connolly
Matterhorn Ascent

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!
