Julie Chick, Water Trail Project Coordinator

Julie Chick was born in Portland and went to Oregon State University where she graduated with a BS in Graphic Design and a minor in Business. Immediately after college, Julie went to work in the corporate world doing various Graphic Design projects. Then she packed up everything and moved to the Big Island of Hawaii into a school bus. Julie spent two years there, bought a jeep, got a dog, and moved to the north shore of Kauai. This is where she learned to kayak, surf and play Ultimate Frisbee. After four years Julie thought "I better get serious" and came home to Portland only to be called back to the ocean. She ended up in Nehalem and bought the little kayak shop in Wheeler that became Nehalem Bay Kayak Company. Julie loves to be on the water and has found Tillamook County to accommodate that need. Just recently Julie has married and has two little boys and is waiting anxiously to introduce them to surfing and kayaking. They can be found at the beach or the river playing in the water.
