Allen Giernet grew up in San Diego and always had a thirst for the outdoors. Whether in the mountains, the ocean, or the desert – he had to be outside. After several years running the youth snowboard competition team at Mountain High, his longing to get into the peaks beyond the resorts took him into splitboarding. This in turn took him into the Sierras, The Rockies, The Cascades, and more. In 2010, he began teaching rock climbing as an AMGA Single Pitch Instructor in Joshua Tree and other So Cal Areas. In 2012, he founded So Cal Snow Avalanche Center, began teaching avalanche courses with the National Ski Patrol, and began to guide on splitboard.
He has traveled all over the west and beyond in search of great climbing and big snow covered mountains to find powder filled descents. But the magical Eastern Sierra will always hold a special place in his heart.
Allen currently calls Methow, Washington home in the North Cascades and still spends time in So Cal. He ski guides and teaches avalanche courses in The Eastern Sierra, Colorado, and the North Cascades. That thirst for the outdoors remains unquenched and Allen loves to share this enthusiasm with anyone and everyone out there. When not out in the mountains searching for the next descent, hiking, biking or paddling, he may be found running The Methow Store with his partner in the Methow Valley. Serving up cold beer and great food next to the best put in on the Methow River.
An enthusiasm for backpacking was Ian’s gateway into the mountains and soon led to a love of climbing. After cutting his teeth on the rock and ice crags of New England he traveled all over the country making ascents of everything from short roadside rock climbs to big peaks in remote areas. Over a decade ago he discovered that the Eastern Sierra hold a magical mix of amazing mountains and climbing, easy access, and good weather. Now this place is home for him and his family.
Though he loves all kinds of climbing, big walls and winter routes hold a special place in Ian’s heart. He rounds out the year with forays to Alaska, Red Rocks, Joshua Tree, Moab, the North Cascades, and Canada.

Following her passion for guiding and the outdoors she spent the summers guiding children on backpacking trips and adults in sea kayaking. Heather enjoyed living in the Portland area, skiing on Mount Hood and doing lots of cycling but eventually she decided it was time to come back to sunny California.

In 1996, he joined forces with Todd Vogel to found Sierra Mountain Center. SP has over 40 years of full-time professional mountain guiding experience.

Larry is a native of the New Jersey shore. Raised as an ocean lover, Larry spent his early days surfing and being in the water as much as he could. Through an active involvement in scouting, as well as an adventurous friend group, Larry found a passion for the mountains. Naturally, this passion had him trade his surfboard for a snowboard, and he went west! Larry graduated from the University of Colorado Boulder with degrees in Environmental Studies as well as Atmospheric and Oceanic Circulation. In Colorado, he fell more in love with the mountains. After graduating, Larry moved to Alaska to explore the wilderness of the last frontier through backpack and canoe guiding. When COVID struck and found Larry abroad in Central America, he came back to the states hoping to get back to Alaska, but discovered the Sierra along the way. And the high peaks and the fairer climate of California was as far as he made it. Larry now resides here in Bishop, where he spends his time exploring the mountains via roped climbing, splitboarding, and hiking. When not guiding, Larry enjoys traveling and climbing the high, glaciated peaks of Central and South America. Larry’s favorite trip to lead in the Sierra is the Bishop to Mammoth backpack as the variety of the terrain offers tremendous opportunities for natural and human history studies! Larry holds a certification as a Wilderness First Responder, a Leave No Trace Trainer, and a AIARE Level I.
Tyler grew up hiking in the Sierra Nevada before being introduced to rock climbing as a teenager. Since that time, he has climbed extensively in this same mountain range, including Yosemite (he has climbed El Capitan multiple times) as well as various other crags and mountain ranges throughout the West. Much of this climbing happened during spring, summer and winter breaks while working as a high school English teacher in southern California. After more than ten years in the classroom, Tyler made a career change and began guiding in 2016. He loves being able to make use of his teaching background while working outdoors and helping people achieve their goals. While climbing is his first passion, Tyler also enjoys hiking, backcountry skiing, running, cycling, and a bit of fly fishing now and then. He lives in Bishop with his wife, Mona.

Anouk grew up on the glaciers and peaks of Switzerland where her family is from and currently resides. Anouk has had an appreciation for the elevated outdoors from an early age. She has lived in Europe, America’s east coast, and finally, she came to the west coast in her teens, and never left. Even though she calls the Eastern Sierra her home, she began her guiding career in the Pacific Northwest, where she worked on glaciated peaks such as Mt Rainier and Mt Baker, and rock guided during the summers. However, having learned to rock climb in California and frequenting the Eastern Sierra during her years living in Los Angeles, she ultimately returned to California eight years ago and has been guiding here year round. In the summers, Anouk guides rock and alpine trips, and during the winter seasons, she ski guides and teaches avalanche courses. She sees her guide work as a way to increase and infuse passion and knowledge into the outdoor community – her way of giving back after having been fortunate enough to receive solid mentorship during her initial years climbing in California.
Anouk is an AMGA Certified Rock Guide, Apprentice Ski Guide, and Apprentice Alpine Guide, as well as an AIARE avalanche course leader and AAI course leader.
