Sam Hennessey
Guiding since 2011
Wyoming
A native of Port Angeles, WA, Sam’s outdoor career began at a young age in the small yet rugged Olympic Mountains. These days, he lives seasonally in Bozeman MT, making the most of the incredible ice and mixed climbing in the greater Yellowstone region. His favorite routes tend to be big walls or alpine rock and ice climbs. He is a former college athlete, and his non-climbing interests include distance running, reading, and traveling to new places. He guides year round in Alaska, Washington, and Montana, and is excited to join JHMG for his first season in the Tetons.

Testimonials
Our climb up the Grand Teton with Sam Hennessey was unforgettable! Sam was a fantastic guide from the very start. He established a sustainable pace to ensure that we’d have enough left in the tank at the end of the day – and we did! Sam was extremely professional and enjoyable the entire time . He was also surprisingly knowledgeable about the history and geology of GTNP. I would HIGHLY recommend climbing the Grand (or any mountain) with Sam, he’s a consummate guide.

It was beautiful, challenging and delightful. Sam [Hennessey], my guide, was knowledgeable, accomplished and easy to get along with. The route that was suggested for me was exactly the right level for my abilities as well as stunning. All in all, a great, full, hard day. I had a great time climbing with JHMG.
