| Duke Dungan 1947-2025 |
Duke developed his strong work ethic at a young age as a paperboy for The Seattle Times. He attended Seattle Public Schools and later graduated from Seattle University with a degree in Chemistry. He met his wife, Sherrill, through the Seattle Chancellor Club, and they married in 1983.
He worked as a chemist for NOAA, conducted soil testing for Washington State, and at Laucks Testing Laboratories before beginning a career in wastewater treatment. He first worked for King County Metro and was later hired by the City of Lynnwood. He served for 33.5 years, including 28 years as Assistant Plant Supervisor, retiring only after being diagnosed with leukemia.
Duke dedicated his life to serving others. He was honored with the “Least of My Brethren” award for serving the less fortunate in his community through the St. Vincent de Paul Society. He served as president and held other leadership roles, and his name is on the pantry door at St. Mark Catholic Church.
Duke was a devout Catholic and an active member of St. Mark Parish, where he taught Latin and religion classes. He was the ultimate career counselor and was passionate about helping others find their calling.
He shared his love of chess with his children by coaching chess club. An avid baseball fan, he coached and umpired for Little League. Duke also loved to sing, particularly Gregorian chant, and participated in many choirs throughout his life. He enjoyed working outdoors on his property.
Duke had a big personality and a wonderful sense of humor. He wanted his grandsons to call him “Grandduke,” but the name never quite stuck. He would gladly sacrifice his dignity if it meant making his grandsons laugh.
Duke is survived by his wife, Sherrill; his children, Zita (Dan), Drew (Elizabeth), and Cletus; his grandchildren, Miles and Hudson; his siblings; and his dear goat, Beau.
