Testimonials For ISM

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
Mont Blanc Ascent

Thanks for a fantastic week. It was really one of the best things I have ever done. I learned a lot during the week, not only about climbing technique, but also about attitude.

Lachlan MacGregor
Bernese Oberland 4000ers

Perfectly paced and tailored, great variety of skills learned. Guiding and Instruction? Thomas was fab! Everything was pitched at the right level (no pun intended), safety was always paramount and everyone had so much fun learning everything.
