Aleph Johnston-Bloom
Executive Director

Aleph grew up in Vermont exploring the woods on her cross-country skis. She ventured out west and fell in love with snow and avalanche studies as Prescott College while pursing her degree in Outdoor Experiential Education. After college an internship with the Colorado Avalanche Information Center landed her in the San Juan Mountains in Colorado. This launched her into a diverse career where she has garnered experience as a highway avalanche forecaster, a backcountry avalanche forecaster, a patroller and a ski guide. She has worked and skied in many of the western states, experiencing different snow climates and spent a summer patrolling in New Zealand. Through all the jobs and travels she has been an avalanche educator sharing her passion for snow. She is the former director of the Silverton Avalanche School, an American Avalanche Association Certified Instructor and AIARE instructor. She loves helping her students learn to have an opinion about the snow and be part of the decision-making process. (Photo credit:

Current Instructors

Bill Romberg

Bill has been active in backcountry skiing, mountaineering, and ice climbing since coming to Alaska in 1990.  He has spent several hundred days in the backcountry all over Alaska, including the Brooks Range, the Alaska Range, and the local Talkeetna, Chugach, Kenai, and Tordrillo Mountains. He is a former president of the Mountaineering Club of Alaska, and has more than 10 years of experience in technical rescue and avalanche response with the Alaska Mountain Rescue Group (AMRG), where he spends considerable time coordinating classroom and field training events related to avalanche skills and avalanche accident response. Bill's interest in snow and avalanche education is a direct result of increasing exposure to avalanche terrain through personal climbing and skiing, as well as avalanche accident response with AMRG. When not working, volunteering with AMRG, or teaching with AAS, Bill can found enjoying the Alaska outdoors with his family skiing, climbing, hiking, or rafting.

Brad Cosgrove

Brad grew up in the Pacific Northwest and fell in love with the outdoors when he had the opportunity to begin working in the outdoor recreation industry at the young age of 14. Since 2000, Brad has lived in the Turnagain Arm region, a great place to play and work on the water (both solid and liquid).  

During his last 18 years working on the snow, he has had the opportunity to work as a ski touring guide, a mechanized ski guide, an avalanche course instructor, and has spent several seasons working with snow sports movie production crews.  He has also worked with avalanche mitigation teams during that time. His real strength comes from countless days in the field both personally and professionally–and an unending desire to keep skiing the backcountry.  Like most snow professionals, Brad has blended his work and play time on the snow with the necessary certifications it takes to stay on the "sharp end" of things, and he has had the chance to gain this experience in a variety of locations and snow climates. Brad is proud to be a part of Alaska's original avalanche school, the Alaska Avalanche School.  

When not obsessing about snow or water Brad can be found enjoying Alaska with his wife Shannan and 3 year old son Will.

Nick D’Alessio

Nick grew up in New Hampshire and has been skiing and climbing in the mountains since before he even remembers. He appreciates having grown up and skiing the icy North East. However, he made the move to Colorado in hope of more snow and to get his degree in Outdoor Leadership from Colorado Mountain College. Then it was up to Alaska to “check it out” and get his Outdoor Studies degree from Alaska Pacific University. He hasn’t left since and is not planning on it, “Why leave good snow to try and find good snow”.  Nick works year round as a professional mountain guide since 2008. He is also a lead guide and instructor for the Alaska Mountaineering School where he enjoys an annual trip to the summit of Denali. He thoroughly enjoys sharing his knowledge of safe mountain travel.

Along with his extensive experience base he holds a Wilderness First Responder, Avalanche Level 3, Leave No Trace Master Educator and is close to earning his Ski Mountaineering Guide certification through the American Mountain Guides Association.

Sean Bio

Sean Fallon

Originally from Rochester, NY, Sean grew up playing in the snowy hills of the Finger Lakes, but quickly realized there had to be more than the icy, man-made ski trails and infrequent snow storms. Alaska Pacific University's Outdoor Recreation program drew him to Anchorage, and the beautiful mountains, unbelievable snow totals, and warm community kept him around. After graduating with a BA in Outdoor Studies concentrating in Snow Science, he moved to Girdwood in search of a better stage for our ritual dances, prayers, and offerings for the snow gods. When he's not looking for powder, Sean works for the Alaska Mountaineering School and for Nova River Runners as a raft guide and ice climbing guide.

Sean McManamy

Like all east-coast kids who love snow, Sean left home as soon as possible.  After a short tour in the rocky west he came to Alaska for its deep snowpacks. Since graduating from Alaska Pacific University in 2007, Sean’s work history includes: Mountain Guide, Avalanche Instructor, Dishwasher, Whitewater Photographer, Handyman, A.P.U. Adjunct Faculty Member as well as volunteering for the CNFAIC Observer Program. In 2008, Sean presented at the Eastern Snow Conference in Vermont (held in the same room as his senior prom) and the International Snow Science Workshop in British Columbia. Most recently, the American Avalanche Review published an article on his work with The Avalanche Terrain Exposure Scale in Alaska. Today he calls the small town of Hope home, and even though  backcountry skiing is his passion, Sean does own and operate a snowboard.

Tucker Chenoweth

Tucker Chenoweth was born in the high windy mountains of Colorado to a pair of devoted skiers.  Instead of attending daycare with all the other children, his parents sent him out on the slopes to learn the ways of gravity.  After a teenage ski racing career and a bachelor’s degree in Environmental Studies, he began pursuing his ultimate passion full time. During a ski patrol career that lasted nine years, he discovered Alaska in 2000 as a volunteer Mountaineering Ranger on the slopes of Mt. Denali.  He was hired as one of the eight paid rangers in 2004, and his adventures have taken him to such exotic locales as the Kitchatna Spires, Mt. Huntington, Mt. Hunter, and many more.  He has also been a part of the AMGA ski mountaineering program and has worked as a ski guide.  The avalanche phenomenon has interested him from the start, he is a professional member of the AAA, an AIARE Certified level one instructor and for the last decade he has studied snow and helped create interest in educating backcountry users.  Tucker enjoys spending his free time with his lovely wife Leighan.

Emma Bio

Emma Walker

Emma grew up skiing in the Rocky Mountains, and loved it so much she stuck around for a degree at CU-Boulder. She graduated with plans to become a classroom teacher, but soon realized she couldn't stand to be stuck inside and miss out on Colorado's 300 annual days of sunshine. After a yearlong stint in Golden at the American Alpine Club, Emma was ready for bigger mountains and more snow, so she packed her bags and headed to Anchorage for graduate school at APU. She hasn’t figured out what she’ll do with her “Master’s in Camping,” but she hopes it will land her a job in the mountains.
