Forrest Baldwin

Born and raised in the mountains of Montana, Forrest's love for the outdoors began at an early age. Numerous adventures around the state and easy access into Glacier National Park lead to a life in the outdoors that never slowed down. Forrest initially came to Washington as a Ski Patroller for the nearby Crystal Mountain Resort, where he continues to work/dominate the slopes to this day. Formerly a Hotshot, he spent the summers fighting wildfires across the United States/Canada before making the transition to mountain guiding and becoming a full-time member of the PNW. Forrest graduated from the University of Montana with degrees in International Business and Spanish and has training in OEC, WFR, BLS/CPR, LNT, and Avalanche Pro-1.

Max Bond

Max Bond hails from the "glaciated mecca" of Cleveland, Ohio, where he learned to climb on graffiti-covered cliffs and ski on 280-foot hills. After graduating high school, he moved to the White Mountains of New Hampshire, where he gained experience ice climbing, trad climbing, and ski-mountaineering on the icy peaks around New England. On the side, Max earned his B.S. in Glaciology and Climate at Dartmouth College where he conducted research on the effects of climate change on avalanche activity. In previous summers, Max has guided in Alaska for the Juneau Icefield Research Program where he helped research teams collect data while completing a 2-month, 75-mile traverse of the Juneau Icefield.

Max has training in AAA Pro-1 avalanche, WFR, LNT Trainer, AASI Level 2 Snowboard Instructor, and the AMGA Alpine Skills Course.

Romulo Cardenas

IMG is fortunate to have The Best partners internationally. Romulo has guided our Ecuador climbs for 20 years. He resides just outside of Quito with his wife, Patricia and son, Camilo. We don't even want to count how many times he's been to the summit of each Ecuadorean summit! He's also climbed with IMG on Cerro Aconcagua, Denali and Vinson Massif. No one knows Ecuador like Romulo. Strong, knowledgeable, friendly and competent are great adjectives to describe our good friend and guide. Romulo gives our Ecuador trips a leg up on the competition.

Adam Clark

Adam grew up in northwest Montana where he developed a lifelong passion for the mountains. He has spent much of the past fifteen years climbing, skiing, and working in the mountains and has guided trips on Rainier, Denali, and Aconcagua. He still loves exploring the Montana ranges, but has also travelled to Alaska, Peru, Nepal, and New Zealand in search of fine alpine terrain. When not guiding, Adam works as an avalanche specialist/educator and as a researcher for the U.S. Geological Survey's glaciology program. He holds an MS degree in geology, has U.S. Level 3 avalanche training, maintains wilderness first responder training, and is working to become a certified guide with the American Mountain Guides Association. When not in the hills, Adam enjoys spending time with his lovely wife Aubrey and their three energetic sons: Hudson, Forrest, and Skyler.

Juan de la Cruz

Juan de la Cruz has been guiding cultural and mountain trekking adventures in Peru since 2005. He holds degrees in Art and Tourism along with English language certification. His Quechua heritage and childhood growing up in the Andean Amazon bring real authenticity and passion to IMG treks. With more than 200 journeys along the Inca Trail, he knows all of the hidden gems of the Inca Trail and Machu Picchu. Juan's presence on IMG treks take a once of a lifetime experience to the next level.

Peter Dale

Peter was born and raised in Everett, WA and learned to love the outdoors in the surrounding Cascades through skiing, climbing and mountain biking. He has climbed and skied all the volcanoes and many other prominent peaks in the Pacific Northwest. After earning a B.S. in Athletic Training at Washington State in Pullman, he returned to the wet side of the state and began guiding during the summers and ski patrolling at Crystal Mountain during the winters (where he is now the Ski Patrol Director). He is a nationally registered EMT and has completed American Avalanche Association Level 1 and 2 training. In his spare time, Peter enjoys climbing and skiing in different places including Alaska, Europe and South America.

Angie Diana

Angie was born and raised in New England where she learned to love the cold and snow. Although she merely tolerated outdoor excursions as a child, she eventually came around and began climbing as a teenager. Since then, she has climbed and adventured in South America, New Zealand, Europe, and (obviously) Washington state. When she's not outdoors, Angie can be found sewing, reading, or working in a plant genetics laboratory.

Jason Edwards


Jason Edwards started his guiding career in the 1970's, and has since guided and led successful ascents of many mountains around the world, including Shishapangma and four successful expeditions to the summit of Mt. Everest. His 2001 Everest expedition became one of the most successful expeditions in Everest history, when 14 of 16 climbers reached the 29,032' summit. Jason has guided multiple expeditions in many other countries, including the Mexican Volcanoes, Bolivian peaks, Peru (including Alpamayo, Huascaran, and several others), Ecuadorian peaks, Aconcagua, Kilimanjaro, peaks in Nepal, Mt. Elbrus in Russia, Mt. Vinson in Antarctica, and various peaks in North America. In 2002, Jason became the 65th person to climb the famed continental "Seven Summits," after his ascent of Mt. Koscuiszko, located in New South Wales, Australia. From 1981 to 2004, Jason also guided for Rainier Mountaineering, where he led several ascents of Mt. McKinley. As an IMG guide in 2006, he reached Mt. Rainier's summit for the 300th time which placed him in the company of only seven other guides who have also achieved this rare feat, and got him featured in The News Tribune's "Heroes and Legends of 2006" article. Jason is a Certified AMGA Alpine Guide and Emergency Medical Technician, and he likes to focus on participant enjoyment and safety, which can be seen throughout the trips he leads and organizes. His degrees in education and business further help International Mountain Guides strive for its goal — providing the best quality adventures possible.

Stuart Johnson

My name is Stuart Johnson, but you can call me Stu. I am a Seattle local and grew up looking at lovely Tahoma (Mt. Rainier) every day. Now it is my office! I got interested in climbing as a young dude through Boy Scouts. I began scrambling and romping around the Cascades and Olympics when I was wee, and see myself doing it for as long as I physically can. I get joy from bringing people into new environments and helping them push their comfort zone and personal limitations — the mountains have so much to teach if we are willing to tune in and listen. When I am not in the mountains you can find me living in my van, writing music, sailing, diving, gardening, foraging, or basically anything else that takes place outdoors. I am a Wilderness EMT and love austere medicine. I look forward to potentially getting to know whomever is reading this on a climb — see you in the mountains.

Emily Johnston


Emily started her climbing career by jubilantly summiting Glacier Peak when she was 13. She spent her teen years climbing in the North Cascades of Washington, and in Oregon and British Columbia. After college, she instructed for Outward Bound in Joshua Tree and Central Oregon, then began guiding on Mt. Rainier in 1989. Over the years she's also enjoyed guiding in the North Cascades, Alaska, Mexico, Antarctica and the Himalayas. Adventure races, whitewater competitions, and personal travels have taken her to the rivers and mountains of every continent. Beyond her alpine life, she's lived/studied/worked in the Dominican Republic, Taiwan, Thailand, France, New Zealand, Australia, Israel, Indonesia, DR Congo, Nepal, and Bhutan. Her training includes EMT-B, Leave No Trace Trainer, Level 3 Avalanche, and MD. When she's away from IMG, she works as a whitewater guide, ER doc, and professional ski patroller. In all of her spare time, she enjoys backcountry skiing, writing, sculpture, trail running, mountain biking, and the occasional refuge of silent meditation.

Emily in the News:

Kassim Juma

Kassim has worked for IMG on the Kilimanjaro programs for many years and has become one of our go to Chagga guides. He passed the Kili guide training course and has some impressive climbing experience with over 300 ascents of Kilimanjaro and over 100 ascents of Mt. Meru. A member of the local Chagga people who live in the Kilimanjaro area, Kassim is 43 and is married with three kids.

Martin Lucero

International trips succeed, in part, because of the partners and relations you have abroad. Martin is a powerful part of our Aconcagua programs. A native of Mendoza, he's there when we need him. Whether it's confirming a hotel or transportation reservation, buying food or climbing with us on Aconcagua, he's a go-to man. Mountains like Aconcagua, Tupungato and Mercedario are his backyard. Since his first ascent at age 15, mountains are now his life. Whether it's winning ice climbing festival competitions, skiing, snowboarding — Martin can do it all. First aid, vertical rescue and high mountain guide courses have only strengthened his resume and value to IMG. You'll likely meet and climb with Martin as part of our guide team on many IMG Aconcagua expeditions. You'll be glad you did.

Chris Magness

Chris's early forays into the woods were on a borrowed mountain bike. The shoes didn't fit and he didn't have a helmet. Still, he was hooked, an adrenaline junkie was born, and he instantly loved the smell of pine duff and its feel beneath his feet. After completing a bachelor's in English, Chris followed the Great Divide Route south on his mountain bike, pulling a trailer, border to border. Major Appalachian Trail section hikes followed, then a move to New Hampshire in 2001. Chris has continued to travel the United States in search of lesser visited places, scaling rock walls throughout the West and South. He has established many dozens of new rock routes in New England and the South, and has worked professionally as a mountain guide, across disciplines — rock, ice, snow — since 2008. During this time, he's had the opportunity to share passions, activities and places, with others, over 1,100 to date. He's as comfortable on a desert tower as a glacier or a backwoods, scrappy New England crag, and if you're with him, you'll feel comfortable too. Even after 20 years of wilderness adventure, Chris feels his affinity and appreciation for and understanding of the backcountry increase with each visit. He has learned that some areas are so incredibly unique and fragile that preservation and conservation are an obligation: part of sharing the intrinsic value of these places with others is consideration of future generations. He is a founding member the nonprofit Keep the Whites Wild.

Patrick Mauro

Patrick grew up sailing in the Carolinas but traded the ocean for the mountains when he began ice climbing soon after college. After cutting his teeth climbing ice and rock in New York and New England, Patrick set his sights on alpine objectives on the West Coast. Since then Patrick has climbed in the Cascades, Sierras, Andes, Himalayas, and Alps. Patrick holds current training in W-EMT, CPR/AED, AIARE Level 2, and Leave No Trace (LNT). He is also an AMGA Apprentice Alpine Guide. Patrick graduated from Harvard College with an A.B. in Electrical Engineering and Computer Science and an S.M. in Electrical Engineering. When not in the mountains, he enjoys photography, aviation, and competing in triathlons.

Porter McMichael

Born and raised in Eastern Washington, Porter first started climbing Washington's volcanoes at age 12. He raced cross country and track during high school and backpacked in the cascades in his free time. After moving to Bellingham in 2016, his affinity for the vertical grew. While attending Western Washington University and running cross country and track for the University, Porter began finding his passion for difficult alpine climbs (especially ice climbs), as well as ski mountaineering. He began guiding for IMG in 2018 and enjoys sharing the unique alpine environments with others. Porter is a Wilderness First Responder and has training in Avalanche Level 1 and Leave No Trace.

Lara Ralich

Lara grew up in Pittsburgh, PA and didn't learn to truly love the outdoors until her late teens. She is actively trying to make up for all that lost time. After an extended road trip across the country that landed her in Oregon, she started to explore the rocks and volcanoes of the Northwest. Lara received a Masters of Architecture from the University of Oregon and currently works as a designer at NBBJ Architects, based in their Seattle office. She has been able to strike a balance between her two careers as a guide and an architect by spending most of the year in the city and the summers on Mt. Rainier and in the North Cascades. She is passionate about teaching people how to interact with nature and the built environment in the most sustainable way. Her favorite days outside are long days on high alpine rock. She currently holds Wilderness First Responder, CPR and Leave No Trace training. While she currently never has to travel far for iconic mountains and rocks, she plans to tap into her cultural roots and start exploring the mountains of Montenegro and other areas in Southeastern Europe during the next couple years.

Dan Riethmuller

Dan hails from the east coast. Born and raised in Pittsburgh, Pennsylvania, he grew up enjoying the outdoors and discovered rock climbing while on a trip to Seneca Rocks, WV. Ice climbing and alpinism followed soon after, and after working in the Outdoor Education field for a few years, he began working for IMG's East Coast division in 2016. He now migrates westward to work and play in the Cascades in the summer months, returning to New Hampshire for the winter Season. Dan cut his teeth trad climbing, and continues to enjoy rock climbing when it's too warm to go ice climbing. He has a BA in Adventure Education, keeps his WFR current, and is an AMGA Certified Single Pitch instructor, as well as an AMGA Apprentice Rock Guide. He is currently pursuing certification in both the Rock and Alpine Disciplines. Time off activities include drinking gratuitous amounts of coffee and enjoying time with his wife.

Nicole grew up in Georgia and first discovered her passion for the mountains through rock climbing, competing in the JCCA Junior Nationals two years in a row. She continued to climb and hike before taking a break from mountain pursuits to earn her MS in Mathematics and become a credentialed actuary. Throughout the next 10 years, her actuarial career and the mountains competed fiercely for her attention. Over time, she honed her skills in ski touring, mountaineering, and ski mountaineering, seeking higher peaks and gnarlier lines until the mountains won, and she knew what she had to do: make the leap and begin her second career in professional risk management, this time as a guide. Among Nicole's ascents are Denali, Rainier, Shasta, Adams, Baker, Hood, Lassen, Shuksan, St. Helens, and Mt. Whitney. She has completed the Eklutna Traverse and Haute Route ski tours. She is trained in AIARE 1 & 2, WFR, CPR, LNT, and the AMGA Alpine Skills Course. When away from IMG, Nicole lives in Brighton Utah, spending winters skiing the "Greatest Snow on Earth" from her doorstep.

Always learning, Shannon is in school studying for an M.S. in Computer Science from MIT. When not in the mountains, you can find her coding up a new startup idea or competing in lacrosse.

Nickel Wood

I've been involved with some type of guiding for the most part since 2007 when I first matriculated to Alaska to learn the ways of climbing. Much has happened since that first visit to the Great North country. I've been blessed to see the world from the tops of Africa, North America, and South America... they all look good and are well worth the journey. I try to always be in pursuit of something and with guiding that is twofold: the facilitation of amazing experience and further certification and training. In addition to guiding, I'm due to finish Yoga Teacher Training school, and when I graduate from the Lexington Healing Arts Academy in Lexington, Kentucky, I'll be a Registered Yoga Teacher through the Yoga Alliance. Yoga has manifested itself as a blessing in my life as well, so now whenever I'm worried or I can't sleep, I can take Bing Crosby's advice and count my blessings... they're numerous. My favorite thing is being alive in the world today... and most things Kentucky — including and especially the Kentucky Wildcats. I'd like to thank any and all who have had a hand in getting me to where I am today... you know who you are! I'd also like to give special thanks to my family at International Mountain Guides. You burst into my awareness like a boon of spring, and for that I am very grateful. Aho mitakuye oyasin.
