Dean was born Dec. 5, 1926, in Philip, South Dakota, the son of Fred and Ada (Swartz) Marrington.

He entered the U.S. Navy in 1943, was honorably discharged in 1945, then returned home to Rapid City, South Dakota, and finished his senior year of high school.

On Jan. 18, 1947, he married Avis Miessner in Rapid City. The couple moved to Gillette in 1952, and in 1962, along with his wife, started the family business, Gillette Plumbing & Heating until 1992 when they retired.

He registered with the American Legion at age 17 when he entered the Navy. He held several positions in the American Legion, including commander and was active in the Drill Team, which he was very proud to be a part of.

Dean was active in the Gillette Jaycees in his younger years and was a founding member of the Gillette Country Club. He was very fond of golf, hunting, gardening and having some beers with his longtime buddies at the Legion.

But closest to his heart was his family, children, grandchildren and great-grandchildren.

Dean is survived by his son, Scott Marrington; daughter, Vicki (Darryl) Worman; daughter-in-law Crista Marrington; grandchildren, Phillip (Jamye) Worman, Eric Worman, Brett (Colleen) Worman, Kristi (Cory) Altenburg, Heather (Ryan) Fichtner, and Sarah and Christopher Marrington; and great-grandchildren, Taylor, Aspyn, Hunter, Parker and Briddger Worman, Van Worman, Sheridan Worman, Lily and Layla Altenburg, and Madeline and Michael Fichtner; and brother, Glen (Rose) Marrington.

He was preceded in death by his wife, Avis; daughter, Susan Marrington; sons, Craig, Mark and Kent Marrington; and his parents.
