Jonathan Cahill grew up in San Mateo, CA making weekend trips to Lake Tahoe where his love for the mountains began.

His heli-snowboard trip in Alaska ignited his passion for winter sports and led him to working for Shasta Mountain Guides for over 5 years. In the winter he is a full-time Ski Patroller for Squaw Valley and has traveled to Australia and Alaska to patrol and guide throughout the season.
