How we started

Aspen Expeditions was founded in 1977 by pioneer American IFMGA Guide, Dick Jackson. AE is now owned and operated by Internationally Certified Mountain Guide (IFMGA) Amos Whiting and AMGA Certified Ski and Rock Guide Britt Ruegger. We take pride in the service and products we deliver. Our commitment to our highly qualified staff of mountain guides, who are all committed to AMGA guide training, fosters our prestigious industry reputation and cultivates our many return clients and families that work with us year after year.

how we grew

In 2018, Aspen Expeditions acquired Kling Mountain Guides from Josh Kling, IFMGA guide and renowned avalanche educator. Rebranded as San Juan Expeditions, our Silverton-based program has earned its reputation as one of the finest AIARE avalanche education programs in the San Juan Mountains. We offer privately guided custom ski, ice, hut, rock and mountain climbing adventures, from Red Mountain Pass and the Weminuche wilderness to Durango. 

In 2022, Aspen Expeditions acquired local competitor Aspen Alpine Guides (AAG). This proud and reputable program was started in 1987 by lifetime avalanche educator, Scott Messina. From the beginning, Scott Messina has been a very large part in making the 10th Mountain Hut Association and Mountain Rescue Aspen the amazing professional organizations that they both are today. The addition of AAG’s veteran mountain guide team has been integral in creating one of the most trained and experienced guide staffs in Colorado.
