About Mike Lewis

Mike is an IFMGA/AMGA Mountain Guide – certified in the Ski, Alpine, and Rock disciplines. Mike started skiing at an early age and was introduced to rock and alpine climbing in his late teens. He began instructing and guiding in 1993 and has since guided rock, ice, and alpine climbing, backcountry skiing, high altitude glacier mountaineering, and he is an AIARE Avalanche Course Leader. Mike has worked throughout the American West and spends a significant amount of time abroad each year. In his twenties, Mike focused almost purely on rock climbing and accumulated many achievements such as Facile (5.14b), numerous big walls, long traditional routes, and first ascents. Mike lived “on the road” for over a decade working on the YOSAR valley team (Yosemite Search and Rescue), instructing and guiding rock climbing, and managing safety in the Argentine off-Broadway aerial show called De La Guarda.

In his late twenties, Mike found his way back to the mountains and continued his alpine & ski guiding career in the Cascades, the Colorado Rockies, the Tetons, and internationally. Mike has a B.S. degree in Recreation Management, an M.A. in Contemplative Counseling Psychology. Mike enjoys sharing in his guest’s pursuit of challenge and adventure and living life to its fullest. He lives in Estes Park, Colorado.

  • My experiences with JHMG have been uniformly outstanding.   Each guide that has worked with me over the years has taken a genuine interest in helping me advance my climbing.  The levels of professionalism, expertise, and interest in teaching among the guides I have worked with has been top-notch.

  • If you want to climb safely with confidence and learn about WHAT you are actually doing and climbing…Pick JHMG.  Hands down the best guys for the job!  YEARS of experience and professionalism are very obvious from the moment you step inside the shop.  Nice guys, well trained and fun to climb with!

    — Darren Davis
  • I just wanted to thank you for setting us up with such unbelievable guides.  They were absolutely solid, professional and fun to be around.  We couldn’t have had better, nor better results.  That climb of the Grand is something I’ll never forget.  I will be back to climb Mt. Moran next.

    —  Paul Edelbrock
  • The climb was so much more difficult than I expected but Mike did an excellent job of keeping me moving safely so I could reach the summit.  Mike also provided surprisingly tasty meals on this climb.
