Testimonials For ISM

Learned loads and acclimatised well during the course. Its obviously been very carefully planned. Guiding and Instruction was excellent. Anders was fantastic throughout and made the whole course really good fun. A very professional instructor with a great sense of humour. Highly recommended.

Summits & Skills 4000m (Instructional Course)

Please pass on my very, very sincere thanks to Thomas, Daniel & Christian. They are truly quality people! Patient, understanding, professional, and wonderful ambassadors for your company. I have experienced many guides over my 50 years in climbing and they rank right up there with the very best.

David Hughes

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!
