Kyle Juszczyk

Kyle discovered the Gunnison Valley and his love of the mountains by way of Western Colorado University.

Kyle discovered the Gunnison Valley and his love of the mountains by way of Western Colorado University. He graduated with a degree in Recreation and Outdoor Education, though he’ll tell you that the most formative aspects of his time at Western were instructing for Wilderness Pursuits and participating on the Western Mountain Rescue Team. Both programs introduced him to his closest friends and laid the foundation for his careers in guiding and mountain rescue. When winter work became available after graduation, he began his professional ski career with four seasons of full-time ski patrolling and then began teaching and guiding for Irwin in 2020. In the summer months Kyle has guided whitewater rafting, rock climbing, and mountaineering in Colorado, Alaska, and Washington. He tries to spend as much time as possible in Crested Butte, but is pulled to the northwest each summer by a coveted position as a Climbing Ranger on Mount Rainier. In this role he is one of few civilian helicopter rescue technicians in the US and executes high altitude technical rescue on the glaciated terrain of Mount Rainier. He’s always found search and rescue to be his way to give back to the mountain community that he loves so much. Kyle does have some free time every now and then and enjoys spending it on hut based skiing trips, overnight rafting trips, and music festivals. Kyle is an IFMGA Mountain Guide, AIARE Course Leader and EMT-IV.

“Minnesota is a great place to be from but you don’t need to stay there.” Aaron took this motto of the ironic Minnesota Alpine Club to heart. Growing up in a steady diet of lake fishing, canoeing, and nordic skiing Aaron then left the Northstar State and spent nearly 10 years working as a guide and ski patroller throughout the Western US and Alaska. After a hiatus to earn his doctorate in chiropractic, Aaron is glad to be guiding again. He is a Wilderness First Responder, AIARE Course Instructor, BICP Mountain Bike Instructor, AMGA Single Pitch Rock Instructor, and is consistently progressing toward further AMGA certification in the Rock and Ski disciplines. Based in Crested Butte with his wife and son, Aaron also works as a chiropractor and serves on the Board of Directors for the non-profit High Country Conservation Advocates. He loves to share the Gunnison Valley and is particularly drawn to teaching new skills in this beautiful outdoor setting. Aaron teaches rock climbing, mountain biking, backcountry and nordic skiing, splitboarding, avalanche education, and is always happy to take a long walk in the woods.

Soon after graduating he moved to Crested Butte, where he has guided skiing, rock climbing, and mountain biking for Irwin Guides over the past several years.

Ben grew up in Colorado and has been playing in the mountains since his parents stuck him on skis at age 2. He studied Biology and Chemistry while at college in Gunnison, served as both the Training Coordinator and a Mission Coordinator for Western Mountain Rescue Team, and guided college students on climbing, skiing, and mountain biking trips for Wilderness Pursuits, where eventually he became the Assistant Manager. For several years, Ben was a full-time Ski Patroller in the winters, and in the summers guided climbing in the Pacific Northwest and Alaska, including multiple ascents of Denali and Mt. Rainier, as well as many peaks in the North Cascades. Ben now lives in Crested Butte year-round, and guides full-time for Irwin Guides, creating personalized experiences for people interested in climbing, biking, rafting, or skiing in his backyard mountains. Occasionally he still guides a large expedition, a technical route on a Colorado 14er, or one of his many favorite routes in the Northwest. Ben is an AMGA Certified Alpine Guide, a Wilderness EMT, and holds a Pro 2 Avalanche Certification. When he isn't guiding, you'll likely find Ben rock climbing in the sun, skiing his favorite powder stash, or on a remote rafting trip with his wife and their dogs.

Born and raised in Vail, Colorado, Lani has lived for mountain pursuits for most of her life. After racing as a Division I Collegiate nordic ski racer at Middlebury College while she studied Environmental Science and Geography, she swapped her skinny skis and immersed herself in the world of backcountry skiing and mountain biking. Racing as a professional enduro mountain biker and adventure bikepacker allowed Lani to live on the road for four years straight, getting to ride in nearly every state and almost every continent. The freedom of mountain biking, trail running and sleeping out under the stars makes her think summer is her favorite season, until the snow falls and skiing takes the limelight. Lani is entering her fifth season guiding full time for Irwin’s Cat Skiing Operation. She works as an AIARE Avalanche Instructor and nordic ski coach. Most recently, she joined the Denali Patrol as a volunteer ranger. She skis for Salomon and is supported by Patagonia and Revel Bikes, helping to allow her to travel immensely when not guiding. You can find some of her writing and film projects on Salomon TV, in the Patagonia Journals and Backcountry Magazine. She absolutely loves Crested Butte. It’s not often to catch her without an enormous smile and eager to share her favorite trails and powder stashes.
