Mark Postle

Mark has been a climber for 17 years, teaching and leading trips since 1994. Based out of Bend, Oregon he travels to Alaska in the spring to guide on Denali before heading to the Tetons of Wyoming for the summer. Winters are split between the thin air of Aconcagua and ski patrolling at home, Mark holds a B.S. degree, graduating with honors in Chemistry. He enjoys pursuing all aspects of the sport from bouldering to scaling glaciated peaks around the world. An avid technical rock climber in his free time, Mark has climbed over 50 5.13s, including the Smith Rock testpiece White Wedding (5.14a). Showing people from all walks of life the skills they need to succeed in the mountains is what he loves the most about guiding.
