Peter Ramos, AMGA guide

Peter Ramos

Peter Ramos grew up in Reno, NV with the Sierras in his backyard. In 1984 he began adventuring in the mountains when his mom took him skiing at the young age of 2. In 1990 he started climbing competitively in indoor climbing competitions. It was at 14 years old when Peter landed his first guiding job, teaching summer camps out of Donner Summit, CA.

Peter left Reno the day after he graduated high school and moved to Bozeman, MT. He attended Montana State University and eventually graduated with a Bachelors degree in Nursing (BSN-RN) in 2009. Over those years he continued to guide for various organizations and learned to speak Spanish while climbing throughout South America doing nursing projects. During that time, he also earned the following certifications; Wilderness EMT-B, Advanced Wilderness Life Support (AWLS), and Adult Cardiac Life Support (ACLS).

He has traveled throughout the world as an Expedition Nurse, carrying out both nursing and guiding responsibilities. When Peter is not expedition nursing, he is working as a community health nurse in the local community health centers.

Peter Ramos’ current focus is to complete the AMGA requirements necessary to become an IFMGA certified guide. Peter is a valuable asset to any mountain adventure, given his guiding history, mountain knowledge, and nursing background.

Nate Opp

Nate Opp

Nate has been a full-time active climber in the Bozeman area for over 15 years. He has established dozens of first ascents in the region and also throughout the world.

Nate is also a lead guide for AMS in Alaska and a senior guide for Jackson Hole Mountain Guides.

Whit Magro

Whit Magro

Whit Magro has guided extensively in the Tetons, The Alaska Range, and right here in Hyalite and Gallatin Canyons. He was the first American to successfully guide an ascent of Cerro Torre in Patagonia among many other guiding achievements in Patagonia, Alaska, and elsewhere. Currently, he only guides a handful of days each year as the rest of his time is filled with running his own metal fabrication business, climbing on his own objectives, and hanging with his family. None the less, he steps in now and then on private outings.

Adam Knoff, Himalaya

Adam Knoff

Adam grew up exploring the wilderness of Minnesota with his twin brother Eric. He likes to claim that after his first climbing class in a small state park named Taylor’s Falls, at the impressionable age of 15, he literally watched the light bulb turn on. From that moment on, climbing has encapsulated every facet of Adam’s life.

At the age of 20, Adam moved to Bozeman to attend MSU but found the calling of climbing was too difficult to ignore. In 2001 he left his life behind in Montana and became a full-time mountain guide working for RMI on Mt. Rainier. Adam has been guiding professionally ever since. With numerous expeditions to the Himalaya, Alaska, South America, and Europe, Adam prides himself on being equally versed in climbing and guiding in big mountain terrain, vertical ice and rock, and long alpine adventures. In short, there isn’t anything Adam can’t climb.

On top of his climbing, Adam was instrumental in starting the Khumbu Climbing School in Phortse, Nepal with the Alex Lowe Charitable Foundation and contributes countless hours organizing the Bozeman Ice Festival and Bozeman World Cup climbing competition held annually here in town.

Now living in Bozeman full time with his wife and six-year-old son Liam, Adam has begun to branch out from merely guiding climbing to guiding fly fishing on the world-class rivers around southwest Montana. Whether it be rivers, mountains, or the vertical world, Adam says guiding has always been his calling, and the enjoyment of sharing an adventure and building a bond with new people remains his favorite part of his work.

Jeff Witt, IFMGA guide, Montana Alpine Guides

Jeff Witt

Originally from the Pacific Northwest, Jeff began teaching climbing in 2001, when he helped a friend with an Alpine Ice Climbing Course in the Grossglockner Alps of Austria. Since then, Jeff’s passion for the sport has extended to guiding alpine rock routes in the Tetons, teaching ice climbing throughout the West, exploring the Tetons and British Columbia on skis, and leading expeditions to Alaska, Patagonia, Africa, and the Himalaya. Along the way, through his personal adventures, he has been honored to climb the granite expanses of Fitzroy, swing tools into the icy runnels of the Cassin Ridge of Denali, wiggle up the frozen chimneys of the Eiger North Face, and visit the summit of Mt Everest. Jeff enjoys every opportunity to share his passion for climbing and is looking forward to swinging tools into ice this winter!
