Rex Gallion

I was raised in Buckley, Washington, where I attended school. After High school I worked in the construction field for a couple years until I was hired with the Department of Natural Resources. I worked for the DNR for approximately 10 years as a Hellitac crew person and supervisor fighting wildfires. During the winter I ran troubled youth crews teaching work ethics and hand tool skills building bridges and trails on Tiger Mountain and Mount Si. In 1996 I started working in the field as a Survey Chainman and Party Chief for approximately 17 years. To date, I have approximately 25 years combined field and office experience.
