Kenneth D. Guidry, 75, of Redlands, died July 30, 2022, after a long struggle with vascular dementia, complicated by a short bout of Covid. Born in 1947 to Fred and Mary Guidry, Ken grew up in San Bernardino where he attended San Bernardino High School and lived for 35 years. In 1982, he moved to Redlands with his wife, Yvette, where he lived the remainder of his life. After serving in the army in the Vietnam War, Ken attended college, then worked as a civil engineer for the county of San Bernardino for 36 years, retiring as chief of county transportation operations. He was involved with the Boy Scouts of America with all three of his sons. Ken was the ultimate do-it-yourselfer and enjoyed working on projects around his home. One of his favorite things to do was travel with his wife, Yvette. He is survived by his wife of 42 years, Yvette; three sons, Marc (Justine), Matthew, and Jonathan (Ginny Hu); siblings Larry, Jeanine (Joe) Hallett, Janelle; and grandchildren Camille, Pete, and Spencer. There will be a graveside ceremony at Riverside National Cemetery in the fall. Donations may be made to the Alzheimer’s Association.
