Sean Isaac is one of Canada's leading big-wall, alpine and mixed climbers. In the past 7 years, he has successfully and safely completed 13 mountain expeditions to all corners of the globe, including Kyrgyzstan, Pakistan, Peru, Patagonia, Alaska, Baffin Island and Northwest Territories. In Patagonia, he has three summits to his credit including the first ascent of the often tried, 800-meter east pillar of the Mummer in Torres del Paine, Chile. The Magic Carpet Ride (VI 5.10 A3+) required 19 days of climbing with 14 of these spent living on the wall enduring constant storms. He has completed three expeditions in the ex-Soviet republic of Kyrgyzstan resulting in 9 alpine ascent; 7 of which were new routes, 5 of these topping out on unclimbed peaks. On his first trip to Alaska, he opened two new alpine mixed lines: Canadian Bacon (ED1 M5 WI4) on Royal Tower and Maxim (ED1 M4 WI5) on Thunder Mountain. In the world-famous Bugaboo range of British Columbia, Sean has opened 5 new routes, including the hard mixed line of Spinstone Gully (TD+ M7 R), which was runner-up in Climbing magazine's "Golden Piton Awards", and Wild Fire (V 5.11+) on Wide Awake Tower’s overhanging northwest face.
Closer to home, Sean has been one of a handful of motivated climbers pushing mixed standards in the Canadian Rockies. He has established over 50 new mixed routes ranging from desperate single-pitch testpieces like Phyllis Diller (M11) to multi-pitch monstrosities like Cryophobia (V M8+ WI5+, 240m). His hardest mixed redpoint is Musashi (M12) in the Canadian Rockies and hardest flash is Ecstasy (M10-) in St-Alban, Quebec. Sean is equally adept in competition having earned 4th place in Festiglace du Quebec, 3rd place in mixed climbing in the prestigious Ouray Ice Craft Invitational and 1st place in the Canmore Speed Competition.
Articles and photos of his expeditions and local climbs have been published in numerous international periodicals including Climbing, Rock and Ice, Alpinist, Men's Journal, Outside, Gripped, Explore, High, Climber, On The Edge, Desnivel, Klettern, Su Alto, Canadian Alpine Journal and American Alpine Journal. In addition, Sean is the author of "Mixed Climbs in the Canadian Rockies" published by Rocky Mountain Books and the forthcoming "How to Climb: Mixed Climbing" published by Falcon Books. He has been featured in numerous climbing videos and television programs including Beyond Gravity, Unleashed, Discovery Channel and Outdoor Life Network. Sean has been climbing for 13 years. He currently lives in Canmore, Alberta, in the heart of the Canadian Rockies, with his partner, Hermien, and their son, Noah.
