Byron E.
Garretson
Aug. 10, 1935 Jan. 22, 2026
Byron E. Garretson Jr., 90, died peacefully in San Antonio, Texas on Jan. 22, 2026, surrounded by family. The youngest of eleven children, he was born Aug. 10, 1935, in Sheridan, Wyoming, to Byron E. Garretson, Sr. and Grace R. Garretson of Claremont, Wyoming.
A graduate of the University of Arizona and Arizona State University, Byron earned his undergraduate and master’s degrees in electrical engineering. He served in the Arizona Air National Guard for six years, working on fire control systems.
He launched a lifelong career as a communications engineer with the Salt River Project in Phoenix. In 1967, Byron moved his young family to Tehran, Iran with E-Systems. The family returned to the Washington, D.C., area in 1974, and then to Dallas in 1978. Always game for a new adventure, in 1982 he took a role with Aramco and relocated to Dhahran, Saudi Arabia. In 1996, he retired to South Texas and remained in the San Antonio area for the next 30 years.
Byron met the love of his life, Sarah Cyrus, in Phoenix. They married in 1959 and shared 66 wonderful years together. They were devoted partners, sharing a passion for sports (tennis, skiing, golf), a zest for travel, but most of all a deep love for family and friends.
Byron is survived by his beautiful wife, Sarah; three sons: Dr. Kyle Garretson (Deanna) of Mountain Home, AR; Dr. Kendel Garretson (Elizabeth) of Fair Oaks Ranch, TX; Dr. Kory Garretson (Carolyn) of Clemmons, NC; former daughter-in-law, Lori Carpenter; seven grandchildren; six great-grandchildren and numerous nieces and nephews. He will be remembered for his quick wit, easy smile, kind heart and gentle manner.
A celebration of life will be held at 10:30 a.m. on Saturday, Feb. 28 at Spring Creek United Methodist Church, 9200 Dietz Elkhorn Road, Fair Oaks Ranch, Texas 78015.
In lieu of flowers, the family suggests memorial donations to the USTA Foundation or to the American Stroke Association (in honor of the extraordinary staff at Methodist Hospital’s Neurosurgical ICU).
