Meet the Founder

SMC SP Parker

Robert “SP” Parker

Robert “SP” Parker, hails from the picturesque landscapes of New Zealand. His journey into the realm of mountaineering began during his days at the University of Auckland, where he delved into the world of climbing alongside the university tramping club (akin to “backpacking” for our American counterparts).

He relocated to Yosemite Valley in 1979. He traveled the US climbing in all the great places: Yosemite, Tuolumne, Colorado, Joshua Tree, Devils Tower, Canada. 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. He has earned IFMGA certification in Rock, Ski, and Alpine disciplines and has served as a past director of the AMGA.

As the torch of ownership at SMC passes into the capable hands of Emma, his passion for guiding in the breathtaking Sierra region continues to burn bright, and he eagerly supports Emma in her new role.

SMC is proud to be employing the talents of guides who are some of the most experienced professionals in mountain guiding. This list is not complete due to it being nearly impossible to catch guides standing still!

Tyler Logan

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.

Tyler’s Certifications:
• AMGA Certified Rock Guide
• AMGA Apprentice Alpine Guide
• AIARE Instructor
• Wilderness First Responder

Michelle Wenski

Michelle is a backpacking and rock climbing guide certified as a Wilderness First Responder, AMGA Single Pitch Rock Instructor and AMGA Apprentice Rock Guide. Michelle grew up in southern California, but after falling in love with snowboarding at Mammoth Mountain, it did not take her long to leave the coastal lifestyle of surfing, organized sports and traffic for the mountain life. She has called now Mammoth Lakes her home for 15 years. You can find her hiking, trail running, mountain climbing, snowboarding, skiing, rock climbing, and adventuring with her dog and friends in her “big backyard,” the eastern Sierra Nevada.
After enjoying a decade of personal trips exploring the High Sierra, Michelle decided it was time to share that joy with others by guiding trips for SMC. Two of her favorite trips are the John Muir Trail and its cross country neighbor, the Sierra High Route. Nothing is better than escaping the fast-paced front country for weeks at a time to find solace in the back country. Day to day tasks at home are replaced by self-sufficient foot travel across hundreds of miles of alpine terrain where basic needs of food, water, shelter and rest become the priority. The only things on the to-do-list include seeking out: vistas, alpine lakes, high passes, open meadows, peaceful campsites and other hidden gems along the way.
Creating tasty backpacking meals is something Michelle enjoys. She has taken years of work alongside talented local chefs and applies it to her backcountry meals.

Anouk Erni

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.

Mija Pedreros

Michael (Mija) Pedreros grew up in Chile and has dedicated the past 12 years of his life to climbing and working as a mountain guide.

Larry Gumina

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.

Dave Stimson

Dave is originally from Alberta, Canada, but has traded in his Canadian passport for his American one, lured by clean Sierra granite and perfect California weather. He graduated from Mount Royal University in 2007 with an undergrad in Ecotourism & Outdoor Leadership and has been working ever since as a ski patroller and avalanche forecaster in Canada during the winters. Dave has been climbing since 2003 and has climbed in Squamish, the Canadian Rockies, The Bugaboos, the Tetons, Red Rock, Indian Creek and Peru, to name a few destinations. His first time climbing in California was in 2103 in Yosemite Valley and was instantly in love. He is excited to be back with the SMC team for his sixth season, and to climb and guide in the Range of Light. Dave holds a Wilderness First Responder certification, and a Canadian Avalanche Association Level 2. He began the AMGA program in 2014 and became a fully certified IFMGA Mountain Guide.

Louie Allen

Louie Allen“Louie grew up in the remarkably charming, yet flat city of Cincinnati, Ohio and spent his youth dreaming of bigger terrain. He found his passion for the outdoors through hunting and fishing, and by exploring the Appalachian Mountains during family vacations and scouting trips. Louie studied Outdoor Education and Recreation Management at Ohio University, where he quickly fell in love with climbing and backpacking and worked as a trip leader and climbing program manager for the University Outdoor Pursuits organization. He holds a Wilderness First Responder and AMGA Single Pitch Instructor certification, and is a trained Assitant Rock Guide and Apprentice Alpine Guide through the AMGA, working in rock, alpine, and ice disciplines.

Cole Thompson

Cole grew up among the glacially flattened fields of central Indiana. Upon graduating from Colorado College with a degree in Geology, he dedicated himself to a career in the mountains. His journey in guiding began on the volcanoes of the Pacific Northwest. A ski patrol job brought him to the Sierra and the high quality rock and perfect sunny days convinced him to stay. Through many failures and success and with the help of friends and mentors, he has gained invaluable experience across many of the world’s mountain ranges. The mountains constantly remind him the learning and growing process is never finished.
He is trained by the AMGA in the Ski and Alpine disciplines and is AMGA certified as a Rock Guide. Cole is trained to the AAA Pro Level 1 standard and is a certified Wilderness EMT.

Lauren (Lo) MacLeod

The Eastern Sierra has always been home to Lauren. Though she only moved here full-time two years ago, she’s wandered Eastside trails with a (relatively) heavy pack since 2003. Since then, she graduated from Cal Poly San Luis Obispo with a degree in Applied Nutrition, a minor in Journalism, and Registered Dietitian (RD) credential. While working in hospitals, eating disorder treatment centers, and virtual sports nutrition coaching, Lauren spent whatever time she could backpacking, climbing, snowboarding, and splitboarding. To feed that endless outdoor addiction, she finally realized it was time to move to the mountains.
Lauren feels like she’s found her purpose: to help others find a personal connection with the outdoors. She will happily coordinate your first sky pilot photoshoot (you’ll get it once you see one) to help you slow down and savor the moment. She’s just as likely to scramble up to a majestic viewpoint as she is to sit in a field of yarrow and tell you about its herbal and medicinal properties.
On front country days, you can find her running to alpine lakes (and joyfully diving in), reading high fantasy, concocting elderberry syrup, or training in aerial arts at SILK Studio down the street from the SMC office.

Lauren’s credentials:

  • Wilderness First Responder
  • AIARE Avalanche Level 1
  • CDR Registered Dietitian (RD/RDN/LD)

Heather Shaw

Ryan Huetter

ryan_huetterRyan grew up near the coastal tidewaters of the Puget Sound in Washington State, but has since traded moss and rain for the sunshine and splitter cracks of the Sierra Nevada.  Since graduating from Western Washington University in 2006 with a bachelor’s degree in Outdoor Adventure Management, Ryan has called the Sierra home. Beginning with leading extended backcountry mountaineering and backpacking trips for the Outward Bound School all over the range, he finally settled down in Mammoth Lakes to enjoy the unbelievable skiing and climbing the Eastside is famous for.

Ryan’s passion for climbing has taken him around the world, from Yosemite Valley where he has climbed more than 15 big walls including a 9 day ascent of Tribal Rite (5.10 A4), to 6 seasons in Patagonia where he has made many major ascents including Fitz Roy and first ascents of remote alpine walls.

But year after year, the Sierra Nevada remains Ryan’s base, and he loves introducing people to the Range of Light.  Ryan’s favorite Sierra climb is definitely the Third Pillar of Dana, of course coupled with fish tacos from the Mobil Station.

Calvin Tague

calvinCalvin grew up near the city of Boston and quickly realized his need to be in close contact with nature. He enrolled at Unity College of Maine in 2010, took a National Outdoor Leadership School semester course in 2011 and graduated in 2014 with a Bachelors of Science in Adventure Based Environmental Education. Shortly after, he moved to the Far East in search of adventure and professional experience. I Nepal, he worked as an educator and guide for Initiative Outdoor, a leadership school in Kathmandu. During his half a year stay he managed to help lead back packing expeditions as well as rock climbing and caving trips. Calvin taught children about the joys of outdoor living at local school and invited students to join him at the office for some bouldering sessions and climbing lessons. Next, Calvin made the decision to move to Vietnam where he worked as a rock climbing and sea kayak guide in Lan Ha bay. Another half a year was spent here exploring his new home island of Cat Ba and journeying into the bay to be the first to summit some of the karsts’ most inviting rock faces. Since Calvin’s travels in Asia he has returned home to the states only to continue his travels.  But since May of 2016 he has made a big change. He’s settled here on the eastside and dedicated himself to guiding in the Sierra Nevada and practicing the art of alpine climbing.

Mike Phillips

mike_phillipsMike is another east coast transplant to California who hasn’t looked back after falling in love with the mountains and deserts of the West. He is a graduate of Oregon State University where he studied outdoor leadership and experiential education. Mike’s professional background in outdoor education brought him to the High Sierra to lead expeditions for Outward Bound in Sequoia and Kings Canyon National Park. Mike has worked for Sierra Mountain Center since 2012 guiding trips in the Mt. Whitney Region, along the John Muir Trail and off-trail throughout the range. During the winter you can find Mike caring for injured skiers and performing avalanche control as a professional ski patroller at Mammoth Mountain. Mike is a professional member of the American Avalanche Association and has completed professional level training through the AAA and AIARE. He enjoys climbing peaks and long walks with good company in the high country of the Sierra, and getting out for big backcountry ski lines on sunny spring days.

Joe Crawford

Joe began exploring the mountains while studying Economics at the University of Oregon. Sport climbing at Smith Rock and mountaineering on the Oregon Volcanoes soon gave way to a love of all mountain sports from bouldering to ice climbing and skiing. Drawn to California, for its superior weather and range, Joe began guiding on Mount Shasta in 2011 and in the Sierra in 2014. Having moved to the Eastern Sierra for the incredible alpine terrain, Joe couldn’t help but find a home in June Lake. Joe enjoys skiing the unheralded terrain of “the loop,” from the obvious classics on Carson Peak to the lesser known powder stashes of Fern Creek. In the summer months, he spends his off duty time climbing the alpine rock routes of the high country, his favorite thus far is the Direct North Buttress of Merriam Peak. When he’s not guiding and playing throughout the range, he can usually be found extolling its virtues in a local hot spring, rambling through the hills with his dog or perched at the local brewery.

  • AMGA Advanced Rock Guide Course
  • AMGA Ski Guide Course
  • AMGA Alpine Guide Course
  • Wilderness FIrst Responder
  • AIARE Level II

Matthew Hoffman

Matthew is originally from Ottawa, Canada, but spent most of his life in North Carolina. Exploring the Blue Ridge Mountains of the Southeast sparked his interest in nature. Recently graduating from the University of North Carolina at Charlotte with a degree in Earth and Environmental Sciences and a minor in Outdoor Adventure Leadership, college was where Matthew discovered a deeper passion for being outdoors. Whether it was hiking, climbing, caving, or canoeing, he got out as much as possible and was a trip leader for other UNCC students. Backpacking in the Rocky Mountains and exploring the canyons, deserts, and peaks of the Southwest was more than enough to push him west. This is Matthew’s first season with Sierra Mountain Center, and he is excited to spend his time exploring the Sierra this summer.

Alwyne Butler

alwyne picAlwyne grew up in Minnesota and, while the flat lands hold a special place in her heart, she longed to explore the USA and beyond.  On her year as a Rotary Youth Exchange student in Thailand she signed up for her first rock climbing course and fell in love with the movement.  Once stateside again she began a NOLS semester and explored the Southwest.  She got some of her first exposure to backpacking, caving, climbing, and expedition-style river trips.  One of her instructors on that course introduced her to Prescott College and she knew she wanted to be part of the community there.  Four years later, with a degree in Adventure Education and a yoga teacher training certification, she began to work wilderness therapy in Colorado and Utah.  Since relocating to California in 2013 Alwyne has worked with many schools to facilitate outdoor education trips and personally explore the Sierra and become a member of the Sierra Mountain Center crew.  Now you are sure to find her scrambling on the granite mountains, biking the single-track trails, and running through the meadows. You can count on Alwyne to be upbeat, positive and always having a good time with an exceptional ability to connect with a wide range of guests on the trips.

Lindsay Fixmer

Since her initiation into climbing in 1999, Lindsay has travelled to world-class climbing destinations and guides clients of all abilities on rock, ice and alpine climbs.
