Selwyn came to NU from Ferndale, WA in the fall of 1963 and was a student there until 1967.  He lived in the dorm the first year and worked off campus for Standard Oil Company of California (Chevron). During those years in the Kirkland area, he was an off-campus, part-time student being a full time husband and dad. In 1967, he transferred to the University of Washington. In 1970, he was almost finished with his four year degree in business when Standard Oil transferred him to Phoenix, AZ.

In 1974, after almost 11 years with Standard Oil, Selwyn resigned to go on staff at a large Church of God in Phoenix. He served as their business administrator for 6 years.  From 1980 to 1987 he ran a plumbing company in Phoenix and then was reemployed at Chevron where he worked until his retirement in 2005. During his last 17 years with Chevron he worked at the San Francisco HQ’s, the Richmond Refinery, the LaHabra, CA offices, and then returned to the Phoenix, AZ area in the late 90s.  He was assigned to their Global Lubricants Division and managed the Wax Business Unit until he retired.
