Guides and Instructors

Trevor Husted
Guide - Instructor
Strapped into boots and skis against his will as a young toddler may have the best thing that ever happened to Trevor. The instance was a jumping off point that spurred growth towards a new found respect for nature that would became a lifelong journey. From the Cascades to the Alps, the Himalayas to the Andes and the mountain ranges, oceans, and rivers in between Trevor learned to shape and carve out a path that allowed him to share this deep connection and passion for the outdoors with others. As an educator, splitboard, and ski guide he brings his experience to the mountains where he shares his knowledge and skills with eager learners. When not skiing or splitboarding he can be found twiddling his guitar, sizzling up some healthy eats, or seeking waves for surf and tacky dirt for mountain biking at home or on the road. More information and his writings can be found at

He began climbing with friends on Donner Summit in high school.
