  • Thank you for taking us on the climb. It was such a blast! Being on the Grand was really neat and I hope to do more climbs like it. Thanks for teaching me many things!

  • 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!

  • 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
  • Totally positive experience climbing the Grand Teton that exceeded my expectations. Guides Nate, Jed and Noah were professional, knowledgeable, with great senses of humor, and I felt totally safe and encouraged to push my limits of climbing to gain confidence and still have fun.  Also to meet Rob Hess and share conversation at high camp was very memorable. The trip was well organized and executed with care and precision. The equipment and accommodations were premier…very comfortable and well laid out. The food was good and satisfying. JHMG made this trip the best climbing experience of my life. Well done JHMG!
