Aleph Johnston-Bloom

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 at 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. 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 Alaska Avalanche School as well as 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.

Brad Cosgrove

Brad fell in love with the outdoors where he grew up in the Pacific Northwest and began working in the outdoor recreation industry at the age of 14.  Since 2000, Brad has lived in the Turnagain Arm region, where he can play and work on the water in its solid and liquid forms.  During the last 18 years working on the snow, Brad has worked as a ski touring guide, a mechanized ski guide, and an avalanche course instructor. He also spent several seasons working with snow sports movie production crews and avalanche mitigation teams during that time.  Brad’s real strength comes from countless days in the field, both personally and professionally, and an never-ending 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. When not obsessing about snow or water, Brad can be found enjoying Alaska with his wife Shannan and 3-year-old son Will.

Brooke Edwards    

A long time Alaskan resident, Brooke Edwards has been involved with the ski industry on multiple levels for going on two decades.  She first received her Avalanche Level 1 certification from the Alaska Avalanche School in 1997 in Hatcher’s Pass and it was that course that made her decision to move to Alaska fulltime.  Since then she has been engaged in the avalanche community as a board member for F-CNFAIC, an avalanche observer, a NOLS instructor, a ski instructor at Alyeska Resort and working on staff for Chugach Powder Guides.  

Eeva Latosuo

Eeva is Associate Professor in Outdoor Studies at Alaska Pacific University and part time avalanche educator with Alaska Avalanche School.  Born and raised in Finland, she has called AK home for the last 10 years.

Eeva teaches Level 1 & 2 courses for AAS and would love to travel around Alaska to teach more custom courses. With all the spare time, she trains her operational avalanche rescue dog, Sisu, and drinks strong coffee.

Elliot Gaddy

Elliot grew up in the Adirondack Mountains of upstate New York.  His family encouraged his love of being in the outdoors from a early age, taking him on many family death-marches, which probably explains why he likes going alpine climbing so much nowadays.

He graduated from Green Mountain College with an Adventure Recreation degree, and moved to New Hampshire to pursue climbing and a guiding career. Elliot started guiding on Denali in 2007, and in 2014 finally made the move up to Alaska full time, lured up by the promise of un-ending powder skiing and the love of a beautiful lady (his future wife).

Now he spends his free time enjoying the climbing and skiing Alaska has to offer and traveling to pursue these passions and his profession. He is currently working on obtaining his IFMGA certification.

Along with the Alaska Avalanche School, he also guides for the Alaska Mountaineering School and Exum Mountain Guides.

Fredrik Norrsell

Fredrik grew up in Sweden, where he started leading groups in the outdoors at 17 years old. He initially came to the USA in 1998, where he earned his MS in chemistry at Utah State University. In his spare time, he volunteered for the university’s Outdoor Program, leading trips and teaching courses in backpacking, mountaineering, and climbing rescue skills. He was also involved with Logan Avalanche Forecast Center providing backcountry observations. Since 1995, Fredrik has worked full-time in outdoor education, spending over 2500 days teaching and leading groups in the outdoors, everything from backpacking in the Utah desert and sea kayaking in New Zealand, to mountaineering in Patagonia and winter camping expeditions. His experience as a teacher was recently summarized by one of his students: "You were by far the best teacher I have ever had—including a lifetime in private school, four years at Harvard, and the rest of NOLS.” When not teaching, Fredrik is pursuing his passion for nature and adventure photography.


Forest Wagner

Growing up in Fairbanks, Forest has a keen appreciation for winter.  He has worked in various snowpacks and currently lives in Juneau.






Graham Predeger

Graham was born and raised in Anchorage. He began skiing the Chugach backcountry in high school as a naive, uneducated teenager. He migrated to the Vail Valley after receiving a natural resource management degree from CSU spending eight seasons working in Colorado as a USFS backcountry snow ranger on Vail Pass. During this tenure, Graham absorbed all the information he could regarding snow and avalanches through formal classes, practical experiences and a few near misses. Working as a forecaster for CNFAIC since 2011 has allowed his snow and avalanche education to continue, bringing Graham full circle back to a more coastal snowpack. He is a Professional Member of the American Avalanche Association and AVPRO trained. A personal goal for Graham has been to further involve and engage the motorized community in the Alaska snow and avalanche scene thru his work at the CNFAIC and the Alaska Avalanche School. Spare time is spent sled-skiing, mountain biking and exploring southcentral Alaska with his young kids, ages 3 and 6.

Heather Thamm

Heather moved from northern Idaho to Alaska in 1998, and immediately fell in love with the remote and mountainous landscape. She graduated from the Outdoor Studies program at Alaska Pacific University in 2003 and has been teaching wilderness, sea kayaking, and glacier travel skills for the program since 2005. In the winters Heather enjoys teaching avalanche education and working as a ski patroller for Alyeska Ski Resort and is currently an avalanche forecaster for the Chugach National Forest Avalanche Information Center. She is also an avid photographer and spends her summers documenting weddings and assorted adventures around Alaska and afar. In her free time she can be found backcountry skiing and packrafting in her backyard near Girdwood and loves exploring new places in Alaska.


Jake Kayes

Originally from Minnesota, Jake spent much of his childhood trying to ski, and play outside as much as possible. Jake first came to Alaska to attend Alaska Pacific University. While in college Jake developed a love for ice climbing and backcountry skiing. During the winter, when not working for the Alaska Avalanche School, Jake works at his alma mater Alaska Pacific University teaching winter travel skills. In the summer, you can find Jake exploring different parts of the Alaska Range, leading courses and guiding on Denali. When Jake’s not in the mountains he lives in Chickaloon, and spends his time fly fishing and packrafting.







Jed Workman

Jed Workman was originally introduced to the mountains on a tiny ski slope in Connecticut at age five. In 1988 his high school outdoor program tied him into his first climbing rope and lured him into an obsession. Jed moved to Salt Lake City in 1990 where he completed a BFA at the University of Utah in printmaking while minoring in powder in Little Cottonwood Canyon. A few years working in the Black Diamond warehouse enabled him to build a small climbing arsenal and put away enough pennies to spend the summers in Yosemite. Several years in Yosemite lead to expeditions to Alaska, Pakistan and China. In 2003 Jed permanently moved to the Matanuska Valley of Alaska with his wife Allie, where they are just as likely to shoot a moose, net a salmon, ski a couloir or clip a quick-draw. Since 2000, Jed has guided for the National Outdoor Leadership School, the Alaska Mountaineering School, Jackson Hole Mountain Guides and for Valdez Heli-Ski Guides. Jed is a professional member of the American Avalanche Association, a US Heli Ski member, avalanche level III certified, a wilderness first responder, avalanche forecaster for Valdez Heli-Ski Guides, and director and a forecaster for the Hatcher Pass Avalanche Center.


Jenna Boisvert

Jenna grew up in Colorado where she cultivated her lifelong connection to the mountains. She found her passion for skiing later in life but then quickly connected it to a means to access the mountains in winter. After moving to Alaska in 2002, Jenna became an adamant backcountry skier devoted to improving her powder-swhishing telemark turn in the big mountains, and then more recently, learning to fit in as an occasional AT skier. Jenna is the former owner of Backcountry Babes, bringing women’s-specific avalanche courses to Alaska. She has an Avalanche Level 3 certification, is a Pro Member of the American Avalanche Association, and has been teaching introduction to backcountry skiing and avalanche courses through multiple organizations in Alaska since 2009. Besides enjoying skiing and the outdoors for her own play, Jenna has worked for many years as a wildlife biologist in Alaska and the Rocky Mountain West, is always on the search for a good wolverine sighting (she has seen 8 so far!), and now has a master’s degree in sustainable design. Jenna enjoys connecting with people, experiencing the amazing awesome of nature, and empowering herself and other people to play smart in the outdoors.

Jessie Haffener

Jessie grew up in Oklahoma, but always knew her heart belonged in the mountains.  From a young age, she developed a love for skiing during annual Spring Break ski trips with her family. Her passion for the mountains drew her to Alaska in 2010 after graduating from the University of Oklahoma.  While she has ice climbed, choss wrangled, mountain biked, and bushwhacked her way across Southcentral Alaska, she is most deeply in love with backcountry skiing, her self-described purpose in life . She became so enamored with snow science after her Level 2 with AAS, that she began pursuing a future in avalanche forecasting.  She has been a board member of the Hatcher Pass Avalanche Center since 2016, focusing her efforts on education and outreach.  Last season as a volunteer she taught Know Before You Go avalanche awareness classes for AAS and rescue clinics for CNFAIC, personally reaching a combined 700+ students!  She is stoked to be interning for the Chugach National Forest Avalanche Information Center this season and to continue teaching courses for AAS. When there is not enough snow in Alaska to ski, she can be found with her husband Sam Galoob, wandering North America in her van the Chimichanga Chaser, exploring desert slot canyons, climbing beautiful granite walls, shredding the finest singletrack, soaking in natural hot springs, and chasing the best Mexican food in all the land.

Bio image - Timothy Glassett.JPG

Timothy Glassett

Tim taught himself how to ski at 16 because he was tired of walking down Cascade Volcanoes (and its way more fun). At 18 he took his first avalanche class in Central Oregon. Since then he has worked as a guide, professional ski patroller, certified avalanche dog handler, avalanche instructor, and a volunteer with SAR groups. He is currently a Highway Avalanche Specialist.  Although he enjoys the summer grind winter will always have his interest.


Chelsea Bomba

Originally from the Matanuska Valley, Chelsea grew up playing in the Talkeetna and Chugach mountains at every opportunity.

Her love for the outdoors landed her in Juneau to complete a certificate in Outdoor Studies through the University of Alaska Southeast. While completing the certificate, she was bamboozled into sticking around and enrolling in an Outdoor Adventure Studies bachelor degree. She called Juneau her home for 5 years, balancing exploration of glaciers, the Coast Mountains and the Tonagass National Forest with academics.

During the summer of 2014, Chelsea received an internship at the Alaska Mountaineering School, where she now works as a mountaineering instructor and guide on Denali and the surrounding Alaska Range peaks.

The new job transplanted her back to south central Alaska in the spring of 2015. That spring, Chelsea took her Level 2 with Alaska Avalanche School and discovered a new passion for snow science and avalanche education.

Chelsea’s first love is skiing but she also enjoys climbing rock or ice, fishing, biking and tasty IPAs.

 Why snowmobile specific classes?  Most avalanche classes are taught by skiers and taught from a skiers or snowboarder’s perspective. If you are a snowmobiler, you are usually told not to high point. Much of your time in class is spent learning techniques that work for skiers or snowboarders. Your instructor may not have any backcountry snowmobiling experience. Avalanche 1 classes are different. The classes are taught from a snowmobiler’s perspective. You will learn techniques that work for snowmobilers by an avalanche instructor who has 20 years of mountain riding experience. You will learn how to avoid getting caught in avalanche situations that are inherent to snowmobiling.

Mike Duffy

I was involved with two avalanche body recoveries in a month’s time as a member of the Vail Mountain Rescue Group in the winter of 1992-1993. At the time, avalanche education was very expensive and many classes emphasized snow science. Myself and three other members of the group thought it would be better to save lives by providing affordable, effective and practical avalanche education. We would rather spend our time educating about avalanches than going on avalanche rescues. We started the Walter Kirch Avalanche Seminars for all backcountry users. The success of the classes lead to them being offered at Colorado Mountain College. In 1996 we offered our first snowmobile specific class. Avalanche 1 was started in 2005 to provide avalanche education to meet the specific needs of snowmobilers.


Mary Gianotti, Operations Manager

Mary grew up in Juneau, Alaska where she found her love for snow (and rain) at a young age playing in her vast, beautiful backyard. She left for Alaska to receive her undergraduate degree in Earth Science from Boston University and to work outdoor seasonal jobs in the American west. Quickly she realized Alaska was her favorite place on earth so she moved back. Mary has been the Program Coordinator of the Juneau Icefield Research Program and has led day trips to eight-week backpacking, glacier mountaineering, and winter courses for various outdoor education and science non-profits such as the Juneau Icefield Research Program and National Outdoor Leadership School. Other hobbies of Mary include baking and finding creative ways to tire out her free range 2 year old puppy, Gilkey. Gilkey will occasionally be hanging out in the office with Mary as well, but most likely after a 10+ mile run. Feel free to come say hi to us in the office. 


Kakiko Ramos-Leon, Program Manager

Born and raised in Mexico. Kakiko, started rock climbing and mountain climbing in college, came to Alaska for first time in 2005 to climb Denali. That's where the seed was planted. He cultivate that plant during a few years until he moved to Alaska in 2010. Due to his passion for the snowy mountains, he learned to snowboard and to ski, took his Level I & II with AAS, and started volunteer with our local Mountain SAR. Now he is harvesting the fruits of the hard work and learning process by enjoying working closer to the mountains, going to the Alaska Range volunteering with Denali NPS or Guiding in Denali. Now he is working behind the scenes of AAS as Program Manager, mixing his engineering skills with mountain passioned people.
