Sean Collon, Mountain Guide, RMI Expeditions

Sean discovered his passion for climbing and the mountains over a summer spent working in RMI's warehouse. Over that summer, he made several ascents of Mt. Rainier and began to explore some of the tremendous climbing opportunities that the Pacific Northwest has to offer. After graduating from the University of Michigan, Sean moved to Seattle in order to be closer to the mountains, and now spends the majority of his free time climbing, skiing and exploring the Cascades.
