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)

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!

David (2017)

The classic alpinism course last week led by Swedish Daniel was excellent! The itinerary was really well planned taking into account the less than perfect weather and the abilities and aspirations of the group - we all learned loads.
