Served:
February 16, 1952 – November 1, 1952 (Commissioner District #1 appointed 2-16-1952)

White Salmon, Washington

Before serving, Roy served in the White Salmon Valley School District from 1910 through 1945 (except for brief assignments at other schools) as a teacher and, later, as Superintendent of Schools. After retiring, he served as a port commissioner briefly before becoming Port Manager. Roy passed away in November 1970 at age 83.

During his tenure as a commissioner, the first Port Manager was hired, the first Comprehensive Scheme of Harbor Improvements was adopted, and acquisition of property in the "Bingen West" area (the SDS mill property in 2010) began.

During his tenure as manager, a barge channel was dredged between the river and the "Bingen West" harbor area, various properties in the area known as Bingen West were acquired, the focus of future property acquisitions moved from Bingen West to Bingen East (the Port's current Bingen Point property), and a significant update of the Port's Comprehensive Scheme of Harbor Improvements was adopted (including an amendment to acquire property in Dallesport).
