I love sharing my skills and passion for ski touring, the most rewarding activity I've found, with others.  In addition to working with Pro Guiding Service, my membership with the Certified Guides Cooperative opens up additional permit areas.  I guide all facets of backcountry riding from remote ski mountaineering expeditions to local terrain management on Snoqualmie Pass.  While I ski all over the planet, Cascadia is my home region.  I credit my earlier years ski instructing at Alpental as influencing my life prioritization around wild snowy mountains.   I then spent winter seasons in Jackson Hole, Valdez Alaska, and eventually the Kullu Valley in the Indian Himalaya to further my progression as a ski mountaineer.  Throughout the learning process, my Cascadian roots keep me in the PNW where I continue to be happily rewarded.

My time in these mountains deepens my appreciation for them and I attempt to give back by partnering with the following organizations:

Cascades Wolverine Project
Mountains to Sound Greenway
​​Protect Our Winters
