Testimonials For ISM

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

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.

Leigh Ritchie
Summits & Skills 4000m (Instructional Course)

Thanks for a great week, in some pretty challenging and extreme conditions. Thanks for keeping us safe, teaching us loads, and being all round fantastic fun. I'd look forward to coming on another trip with you guiding.
