Sandeep Nain

CEO & Guide

Sandeep began his climbing career in the Pacific Northwest, and enjoys rock climbing, ice climbing, and backcountry skiing. He has climbed and guided extensively in the Cascades, and summited the volcanoes of Washington multiple times. Some of Sandeep's favorite climbs in the Northwest are the Torment-Forbidden-Traverse, Liberty Ridge, the Coleman Headwall of Mt. Baker, and the North Ridge of Mt. Baker. Although Sandeep is known by the climbing community for climbing big alpine routes, his first passion is rock climbing. On sunny days you can find him climbing with friends at Mt. Index, trying-hard on steep crimps at Exit 38, or in the winter pulling on plastic in the gym. He enjoys projecting 5.12 routes as much as climbing long rock routes in the backcountry.

In addition to a depth of climbing experience in the Pacific Northwest, Sandeep has extensive high altitude climbing and guiding experience. Some of Sandeep's first high altitude climbs were in the Indian Himalaya, where he and two friends achieved three first ascents of technical six-thousand-meter peaks in the Miyar Valley which were documented in the American Alpine Journal. He has also been active in Mountain Rescue, and earned the Life Saving Award for an especially difficult and dangerous mission.

These days Sandeep can be found responding to emails on his laptop at the warehouse, playing with his three daughters, helping customers at the shop, or climbing with Miyar Adventures guides during their time off.

GLEN YOUNG

Climbing Program Director and Lead Guide

Hailing from the great flatlands of Michigan, Glen started life with everything he needed to become a Himalayan climber.  Cold weather, stacks of National Geographics, and casserole.  As little Glen grew into a little man he practiced martial arts and backflips before realizing that being Batman was not a real profession.  And so, he switched to mountain guiding.   Aided by a New Zealand graduate degree in Recreation and Tourism Management, Glen brings extensive experience as a program director in the Outdoor Education and Tourism fields, where he developed international travel programs for which he received awards through Rotary International and the Mathew A. Baxter Memorial Fund.  

Twenty years later Glen continues to climb mountains for what he calls “work.”  Mountains across North America, South America, Asia, Africa, and the South Pacific have all seen the bottom of his expedition boots.  Glen's climbing and guiding career has included many climbs above 20,000 ft., including technical climbs of peaks such as AmaDablam and Kyajo Ri in Nepal and big glacier routes in Alaska. He's climbed routes on El Cap, Half Dome, and Big Walls in Zion in addition to hundreds of multi-pitch rock routes around the globe. Here in the Pacific Northwest he enjoys guiding complex alpine objectives such as the North Ridge of Forbidden Peak and the North Face of Mt. Shuksan.  

Glen’s primary habitat is a gear strewn apartment near Seattle out of which he works as the Climbing Program Director for Miyar Adventures, and the Director of US Operations for Karma Project, an NGO serving rural communities in Nepal.     

He also burrows into ice in Ouray during the winter, smears up sandstone in Red Rock Canyon near Vegas in the spring, lumbers up 20,000ft peaks in the Himalayas in the Fall, and kicks steps up Washington’s glaciers in the summer.  His favorite sound is a package delivery truck and his favorite smell is discount guacamole.
