I could not have considered Cho Oyu without you, and I am very grateful...
~Jim C.
I also found that Eric Simonson's reputation and experience in the Himalaya has given IMG leaders greater ease in dealing with the Chinese government, in choosing more experienced climbing Sherpas, and in interacting with the leaders of the other expeditions. It was this kind of experience, or lack of it, that determined which expeditions were successful and which were not...
~Greg Y.
It wasn't only the correct decision but how you arrived at it. All our expedition members became part of the process. We all learned from analyzing the risks. Thank you.
