William “Bill” Trees, 86, of Riverton passed away at the Sage West Hospital – Riverton on Sunday, February 19, 2023.  A funeral service will be held at 10:00 am on Friday, March 3, 2023, at Lighthouse Bible Church. Immediately after the service the family would like everyone to join them for a dinner in the fellowship hall.


William L. Trees was born on August 26, 1936 in Laurel, Montana to Dwayne and Alcidene (Kenyon) Trees. Bill grew up in Greybull graduating form Greybull High School then attending Tacoma Technical School where he focused on cabinetry and furniture making.


He was a member of the Lighthouse Bible Church and enjoyed being active in his church.


On June 3, 1956 he married the love of his life, Mary Ann Nagle, in Greybull, Wyoming.  They would have celebrated 68 years together this June. Together they raised two boys, Roy and Rodney.


Bill started working for Pure Gas and Chemical Company in 1955 to 1966, moving from Greybull, Pinedale, to Riverton.  In 1968 he started working for Union Carbide Corporation at Gas Hills, Wyoming, being transferred to Bishop, California, Blanding, Utah, and Grand Junction, Colorado until he retired and returned to Kinnear, Wyoming in 1990.  He worked with Roy and Karley to establish Central Wyoming Pawn from 1993 until 2005.


Bill enjoyed hunting, fishing, and woodworking.  He loved his granddaughters and spending time with them. He taught them to fish, ride horses, love camping and Roger Miller. He loved God, his wife, and his family more than anything in the world. His family couldn’t have been more lucky to call him theirs and loving them unconditionally.  He loved KFC for lunch and going to Roy and Karley’s house after church on Sundays for coffee.  Bill also looked forward to the television show, Yellowstone on Sunday evenings.  He delighted in drag racing with family but never did understand why it cost so much money.  Bill cherished the times he spent packing in to the backcountry with family and friends in search of elk.


He is survived by his wife, Mary Ann Trees; sons, Roy (Karley) Trees and Rodney Trees; and granddaughters, Kylee Trees, Kirstee Trees, Alexa Trees, and Krista Trees.


He was preceded in death by his parents, Dwayne and Alcidene Trees; and brothers, Gene Trees and Larry Trees.
