Char Genevier Wyman

Char discovered her love and talent for software engineering while in high school, and built her first company at the age of 15, but her love of the mountains precedes that. While in middle school, she begged her parents to let her learn to rock climb, despite not knowing anyone who did. She spent two years at Harvey Mudd College studying theoretical math (in between bouldering problems at the local climbing gym) before dropping out to devote her full attention to building SocialEngine, a white-label social networking platform. As its CTO, she bootstrapped SocialEngine to profitability, took the company through TechStars Boulder in 2011, and eventually sold it to the digital marketing agency Room 214. She moved on to become CEO and founder of The Cotery, a platform for artists and designers to design, pre-sell, and manufacture unique limited-run apparel without the upfront costs and complications of traditional manufacturing. In between all the startups and the coding, Char picked up a ski addiction, which only deepened when she got a taste of the backcountry. Char now spends her work time consulting and building apps for direct-to-consumer eCommerce brands via her company Conjured, and as much of her free time as possible on skis.

Colin Mitchell

Chris Warner

Chris has earned his fear of avalanches. He’s been picked up, tumbled around and buried up to his neck by an avalanche in Tibet. He’s been knocked over and had his pants pulled off by an avalanche in Colorado. And when he fell for 450 feet through the air when a rappel anchor failed on Shivling in India, he triggered an avalanche when he slammed into the slope. That avalanche tried to pluck him from the peak, but he just wasn’t fated to die that day. He knows how lucky he is, having lost more than a handful of friends (smart and experienced climbers) to avalanches.
As a certified Alpine Guide, he’s studied avalanche forecasting and rescue (the old Level 1, 2 and 3 courses) but still got caught when the deadly combination of weather, terrain and gravity created the alchemy of avalanches. It is this conundrum (avalanches wiping out even the most skilled and educated adventurers) that inspired Chris to join the AIARE board of directors

. Chris, who has been climbing for more than 40 years, has led over 230 international mountaineering expeditions: from Antarctica and South America to New Zealand, Africa, the Alps and Nepal. He’s summited six 8000 meter peaks (Everest, K2, Lhotse, Makalu, Cho Oyu and Shisha Pangma) and pioneered new routes, alpine style, on Ama Dablam and Shivling. He’s also climbed big walls, frozen waterfalls, boulder problems and sport routes. A lover of plastic, he opened his first (of seven) indoor climbing gyms in 1997 and sold that company, Earth Treks, in 2017. In addition to climbing, Chris is fascinated by leadership. He taught leadership for 16 years at the Wharton School of Business. He’s also worked with covert and special ops teams, CEOs, NFL and NHL teams and Fortune 100 companies (from Google to Morgan Stanley, etc). He is the co-author of High Altitude Leadership and is a keynote speaker. These days Chris is still climbing big peaks, skiing and skinning. While he claims to be retired, he still teaches leadership, mentors entrepreneurs, invests in companies in the fitness and outdoor industries and serves on several for profit boards. Chris, his wife Melinda and daughter Wendy live in Golden, CO (but he is usually found in Aspen).
