Sam Hennessey

Washington, Alaska, International

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 guides for Alpine Ascents in Alaska and the Cascades, and has been lucky enough to make two trips to Antarctica. A former college athlete, his non-climbing interests include distance running, reading, and traveling to new places.
