Dave Rosen

Alpine Ski Coach

I am a professional Big mountain skier working with sponsors including Parlor Skis,
Zeal Optics, FlyLow gear, Grass Sticks, and Free The Powder. I grew up racing in NH
and was Captain of New Hampton School Ski team. I spent the last decade in Park City,
Utah where I coached U10s/12s covering a wide range of skill sets on the hill. Over the last 4 years I have been focusing on bringing park style airs to the backcountry and attacking steep secluded lines. I credit 100% of my abilities to my race background. I preach hard work, safety on the hill and the importance of taking calculated risks by using everything in your surroundings to your advantage. I am very excited for the opportunity to spread my passion with The McCall Winter Sports Program.


Mark Beaver

Big Mountain Freeride Director

I was born and raised in McCall and took my first trip up the Brundage rope tow at age 3. Almost every winter since I’ve spent my weekends exploring every inch of skiable terrain in and around Brundage. Soon after first starting to backcountry ski, I attended graduate school through the University of Idaho’s McCall Outdoor Science School (MOSS). Here I became fascinated with snow and avalanche science, and outdoor leadership leading to obtain Avalanche 1 and Wilderness First Responder certifications.  I’ve since worked with MOSS, Payette Avalanche Center, Sawtooth Avalanche Center, and the Environmental Resource Center (ERC) in Ketchum on youth education related to snow and avalanche science. The Big Mountain Program offers the perfect combination of appreciation of outdoors knowledge and the pure joy of skiing. bigmtn@mccallwintersportsclub.org

Willie Adicoff

Big Mountain / All Mountain Coach

While born in sunny California, I moved and spent most of my younger days in Sun Valley, learning the basics of skiing on the alpine racing team.  While visiting other resorts for racing, I would often find myself enjoying the chutes, cliffs, and steeps of those places more than the gate smashing.  All the while, I was slowly picking up skills for backcountry skiing and avalanche awareness.  After going to school in Denver and realizing the skiing I had left behind, I moved back to Idaho and enrolled in the McCall Outdoor Science school where I fell in love with skiing the boundless powder of Brundage, Tamarack, and other local backcountry destinations.  Meeting Mark Beaver led me to coaching with the Big Mountain team with MWSC for a winter and then coaching the All Mountain team, where I can draw from a racing background to teach basic techniques used by all skiers.  Sharing the deepest stashes and best lines is what skiing is all about! Let's rip...

Erica Laidlaw

All Mountain Ski Coach

Native to McCall, I return home after spending 17 years chasing various skiing and academic pursuits.  After this, I am excited to reunite with the mountains that shaped me and work with aspiring young skiers.  My upbringing on the McCall Ski Racing Team built my foundation as a skier - from it I went on to attend Burke Mountain Academy (racing FIS/NorAm) and later to compete on the Freeride World Tour.  Most recently, however, I put skiing aside to finish my Masters i n Architecture from UBC.  Today, with my degree completed, I am eager to reacquaint myself with my Idaho roots and be involved in both racing and big mountain programs in McCall, Idaho.
