  • Climbing a traverse with Mike Poborsky is like watching a ballet. He is a consumate professional and climber. The Middle Teton- Cloudveil traverse was the climbing highlight of my summer!  Thanks Mike and JHMG!!

  • I had a great experience with Mike Poborsky.  He was on time, knew the terrain and how long it would take us and allowed for enough sleep prior to our summit day…  Mike was safe and I enjoyed climbing with him.  He taught me … new tricks/ techniques to use less gear for anchoring and rely more on the rope…  Had a great experience with Mike and if/when the N. Face ever becomes climbable again I’ll hire him to guide me up that as well.  Thanks JHMG!

  • JHMG was just what we were looking for! Our guide was very friendly and professional, and did a great job coaching us along the way. Not only did we get to enjoy a beautiful hike up to disappointment peak, we were able to learn some new tricks and techniques along the way. The small amount of rock climbing gave us a taste for what we would like to experience more. Thank you JHMG and Mike Poborsky for a great day in the Tetons!

  • 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.
