Company History

A foundation built on tradition…

Founded by stonecutter Don Tresko in 1954, Tresko Monument Inc. & Washington Stone has been known for its strong work ethic in fabricating high quality stone products at a fair price. Having learned the granite and stone cutting trade from his father in Portland, Oregon, before and after World War II, Don purchased Washington Monument, Spokane Monument and Swason Stone in 1972. Since Don’s passing in 2006, sons John, Bill and Dick with over 50 years combined experience have maintained the same quality workmanship, traditional values and dedication to customer service. Each enduring stone product by Tresko Monument Inc. & Washington Stone is cut with precision and finished by hand.
