    Guide: Washington, Alaska

    Koby grew up and found his love for the outdoors in the vibrant forests surrounding Portland, Oregon. In high school, he joined a student-run mountaineering club where he discovered a passion for climbing, mountaineering, and outdoor leadership. The hook was set. After high school, Koby moved to Maine and in 2017 graduated from Bates College with a degree in Environmental Studies. Enthralled by the hard, old-school, climbing ethics of Cathedral Ledge, Koby would sneak away to the granite-laden hills of the Northeast at every opportunity. Koby’s guiding career began soon after with winter ascents of Mount Washington (NH) and technical ice climbing throughout the valley. He soon found his way back West, where he guides ascents of large glaciated mountains throughout the Cascades and Alaska as well as rock climbing on the volcanic tuff of Smith Rock State Park. Koby is stoked to guide you and to share his passion for learning and living in the outdoors.
