Members at Large


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.

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 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 one of only two Americans to summit all fourteen of the 8000 meter peaks (Everest, K2, etc) and pioneered new routes, alpine style, in the Himalaya. 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.

Chris Bremer

Chris is the Snowbird Snow Safety Supervisor and calls Little Cottonwood Canyon in Utah his home. His journey to Snowbird started long ago on the frozen slopes of the Adirondack Mountains in New York. From there, college took Chris to the Front Range of Colorado where he got an Engineering Degree from the Colorado School of Mines, and more importantly, started dabbling in the snow covered Rocky Mountains.  Choosing to leave behind the engineering world for snowy slopes has allowed Chris to work as an industrial avalanche forecaster in Chile, an AIARE certified recreational instructor throughout the western US, and to obtain his Canadian Avalanche Association Operations Level 2. Chris joined the AIARE Instructor Staff as a member of the PRO Instructor team in 2019. Currently, Chris stays busy forecasting avalanches at Snowbird, organizing training for the ski patrol, and teaching AIARE Professional Avalanche Courses.

Jeff started his backcountry ski adventures in 1995 on the Colorado front range. During his time in the backcountry Jeff has witnessed avalanches in a variety of terrain—from the side country to alpine climbs—and believes in the importance of quality education experiences to safely learn to navigate the backcountry. Professionally, Jeff creates and manages product lines for the global commercial aviation market.  Chances are, if you have flown commercially anywhere in the world, Jeff’s solutions have been in the cockpit of your flight.  Jeff also served six years on the board of the Access Fund (A non-profit organization that protects and conserves climbing areas throughout the United States) including two and half years as board treasurer.

Kate Beezley

Kate Beezley grew up in the perfect temperatures of San Diego, scampering around the Sierras in the summers. It was only when she moved to Colorado in 2005 to work on her Ph.D. in History that she discovered the joys of sliding around on sticks. Kate immediately dove head first into backcountry skiing, only later taking ski lessons to learn better technique, completing the AIARE I and 2 courses along the way. Her skiing may be ugly but she loves it, having completed a handful of Grand Traverses from Crested Butte to Aspen and other endurance ski races. Since 2018 Kate has represented climbers and built more sustainable climbing infrastructure for Front Range climbers as the Executive Director of the Boulder Climbing Community. Before that, she was a graduate student, a history and social studies educator, and an alumna of Teach for America. She is passionate about mentoring other women in the outdoor industry.
