IMG Mission Statement

To provide the highest quality mountaineering instruction in North America. To train our clients to become competent mountaineers and educate them to be great stewards of the environment. To provide meaningful employment for our guides who are the core of IMG and to preserve and protect the mountain environment we all enjoy — now and into the future.

About Us

International Mountain Guides directors Phil Ershler, George Dunn, Eric Simonson and Paul Baugher organize and lead climbing, trekking and mountaineering expeditions around the world, from the classic climbs of the Alps and Andes to the 8,000m peaks of the Himalayas. We continue to be one of the most respected and active guiding companies in the world. Since 1986 we have conducted hundreds of expeditions to destinations around the globe, and the fact that most of our customers climb with us again and again tells us we're doing things right!

Our Credentials

The single most important question to ask when searching for a guide service is: "Who is actually doing the guiding?" If you are not 100% satisfied with the answer, look for another organization. IMG's leaders are among the most experienced guides in the world, and their track record is impeccable. Eric Simonson, Phil Ershler and George Dunn each have over 40 years of guiding on Mt. Rainier and dozens of expeditions on Denali, the proving grounds of American alpine guiding. Internationally, they've each summited Everest, and their resumes include the world's great climbs: K2, Kangchenjunga, Shishapangma, Cho Oyu, Vinson, Aconcagua, and many more. Simonson, Ershler, and Dunn are American Mountain Guides Association (AMGA) certified alpine guides.

How Are We Different?

In addition to our unmatched credentials, we operate our business differently. Each trip is organized personally by one of the three founders and owners of IMG: Phil Ershler, Eric Simonson, and George Dunn. This means that from beginning to end:

  • You deal directly with the person responsible for the quality of your trip
  • You deal directly with a highly experienced guide and mountaineer
  • You deal directly with an International Mountain Guides owner who is 100% committed to the long-term quality of IMG's programs.
