I am a Spokane-based outdoors and travel writer and photographer. My writing and photography have appeared in numerous publications, including Adventures NW, Around the Pacific Northwest, Spokane Coeur d’Alene Living and Montana Outdoors. In addition, I am Eastern Washington Regional Correspondent for Washington Trails magazine. I am currently working on the guidebook Day Hiking Mt. St. Helens (with Craig Romano), to be published by Mountaineers Books.
My photographs have been featured in galleries and solo exhibitions throughout eastern Washington, and four of my prints are part of a permanent exhibit at the Northwest Museum of Arts and Culture in Spokane. I am also the webmaster for the Washington Native Plant Society.
Prior to embracing outdoors and travel writing full time, I was a science writer and editor for almost a decade, during which time I wrote or edited over one hundred publications for some of the world’s premier genetics journals.
In addition to hiking, I am an avid cyclist and runner and have competed in two Ironman triathlons.
