About C. Dale Slack, Columbia County Prosecuting Attorney

1619631597321I was born in Pullman, Washington and grew up in and around the farming country of Canyon County, Idaho. I attended public schools for my K-12 education. I attended Boise State University for my undergraduate education where I earned a Bachelor of Science degree in Political Science (Public Administration emphasis), and a history minor; I then attended the University of Idaho College of Law, earning my Juris Doctor in 2006. I was admitted to the Washington State Bar in November of 2006, and practiced with a private firm in Walla Walla for four years, during which time I worked as a contracted public defender for Columbia County; I opened my own office on Main Street in Dayton in 2011, continuing my public defense work in Asotin, Garfield, Columbia, and Walla Walla counties, College Place Municipal Court, as a contractor for the Office of Public Defense in child welfare dependency proceedings, and for a short time representing individuals committed to the Special Commitment Center on McNeil Island. In 2015, I joined the Columbia County Prosecuting Attorney’s Office as a Deputy Prosecutor, until 2018 when I ran for the elected position of Prosecuting Attorney. I have practiced before all levels of the Washington State courts, the United States Court of Appeals for the Ninth Circuit, and the Nez Perce Tribal Court in a variety of cases ranging from speeding tickets to murder.

I am proud to represent this great county and to work hard to preserve the peace, safety, and pastoral lifestyle that we all enjoy as citizens of Columbia County.
