Nathan Perrault


After graduating high school in Maryland, Nathan enlisted in the Marines at 17 years old as an infantryman where he served in Iraq and Afghanistan. After his military service, he moved to Colorado to pursue a degree in Natural Resource Management at Colorado State University (CSU). During his time at CSU Nathan cut his teeth in climbing and backcountry skiing in the Poudre Canyon and Rocky Mountain National Park. 

After graduating from college, Nathan soon began working and guiding military veterans on adventures from ice climbing in New Hampshire, to backcountry skiing in Colorado, and climbing many of the glaciated peaks in the Pacific Northwest. Through his work with the military community he has climbed peaks such as Denali, Mt. Rainier’s Liberty Ridge, the North Ridge of Mt. Stuart, multiple routes on Dragontail Peak, and many other alpine climbing objectives in the PNW. Nathan has also climbed in New Zealand and a 6,000 meter peak in Argentina.

His big philosophy is mentorship. Just as he was mentored by so many in his formative years (and still has several mentors!), he loves to give back and educate those who are just getting into the hobbies he is passionate about. When Nathan isn’t working you can find him climbing, skiing, or mountain biking in Colorado, Utah, Wyoming, Montana, Alaska, or Washington. 

Nathan is an apprentice alpine and ski guide, a single pitch instructor, and a Wilderness EMT.
