    Observer

    I grew up in the mountains outside of SLC, UT and fell in love with snow and being outside! My personal and professional life are a wonderful tetrus game fitting together adventure time on rivers, oceans, rock faces, snowy mountains, and everything in between. I am a professional observer for Central Oregon Avalanche Center, an AIARE instructor and apprentice ski guide, a rock guide for Chockstone Climbing Guides, and a NOLS whitewater and sea kayak instructor. I love going on runs with my pup Greg, giggling with my husband James, or snuggling up with a good book.
