Matthew is a Lead Meteorologist and certified Incident Meteorologist with the NOAA National Weather Service (NWS) in Pendleton, Oregon. Prior to joining the NWS in 2020, Matthew spent six years as a broadcast meteorologist across Louisiana, North Carolina, and Oregon. His time broadcasting in Eugene holds a special personal milestone, as it was there he met and co-anchored with his wife, who currently works as a broadcast meteorologist in Tri-Cities, WA.
Before his time in television, Matthew’s career began in research and teaching. He served as a research scientist at the Cooperative Institute for Research in the Atmosphere (CIRA) in Fort Collins, CO, and with the U.S. Forest Service at the Fraser Experimental Forest. During his time in Colorado, he contributed to vital field projects, including snow surveys, beetle kill evaluations, and a NASA remote sensing initiative focused on calibrating snow depth and snow-water-equivalent (SWE) measurements from airborne and satellite platforms.
A lifelong snow sports enthusiast who spent his college years working at a local ski shop, Matthew is deeply passionate about blending his love for the mountains with a commitment to keeping backcountry recreationists safe. His journey comes full circle today: attending this very workshop in 2022 inspired him to step up as the Team Lead for the Avalanche Program at NWS Pendleton.

Katie is a lead forecaster for the NWAC in Leavenworth, WA. She began her career in the snow and avalanche industry studying the remote detection of avalanche activity through the Masters of Geology Program at Central Washington University.

In addition to skiing and digging in the snow, you can find her adventuring in the mountains via bike or running shoes with her dog Nimbus in pursuit.

Sierra is a Ski Patroller, Ski & Alpine Guide, and AIARE Avalanche Course Leader, splitting her time between Salt Lake City, the Pacific Northwest, and chasing winter down to the Southern Hemisphere to patrol in New Zealand.

Koby's love for the mountains bloomed in high school when he was first introduced to climbing and mountaineering through an outdoor program. From rime ice-covered days on Mt. Hood to aching fingers after a weekend of climbing at Smith Rock, he quickly realized that challenge, joy, and growth often come hand in hand in the outdoors.
His pursuit of adventure took him across the country to Bates College in Maine, where he earned an undergraduate degree in Environmental Studies in 2017.
Now based in Portland, Oregon, Koby guides rock climbing, alpine climbing, and backcountry skiing throughout the Cascades and beyond. He meets every client where they are, whether that's an introduction to rock climbing or a technical alpine objective, and aims to create a supportive environment where people can surprise themselves with their true abilities. Whether it's long summer days climbing in the alpine or dawn patrol missions for first tracks on Mt. Hood, he's passionate about helping others experience the same sense of adventure, connection, and discovery that drew him to the mountains in the first place.
In 2024, Koby co-founded Trillium Alpine Guides to bring that same ethos to guided adventures and avalanche education across the Pacific Northwest.

Dr. Fink is an emergency and wilderness medicine physician practicing in Central Oregon. Dr. Fink has worked as a NOLS instructor, professional ski patroller, avalanche observer, and on-hill ski physician. He serves as the medical director for the Mt. Bachelor ski and bike patrol and as a member of Deschutes County Search and Rescue. He is a contributing writer at The-High-Route.com and the host of the podcast Wilderness Medicine Updates, the #2 Wilderness Medicine podcast in North America. When not wearing his medical hat, he enjoys moving through the mountains by any and all means. You can find him online at linktr.ee/finkmd.

Gabe has been working as a forecaster for the Central Oregon Avalanche Center since COAC began issuing forecasts in 2020, and has been a professional observer since 2013.

Gabe lives in Tumalo with his family and enjoys putzing around the garden and reading all the books that he was supposed to (but never managed to) read when he was in school.
