Billy Logan Sisk was born January 16, 1932, the only child of William Elmore Sisk and Minnie Frances Loftis Sisk in Rockwall County, Texas, and grew up outside Royse City, Texas. He passed peacefully from sleep into life eternal at home on Monday, June 15, 2026 after a short illness.

He attended Royse City schools, where he played on the high school football and baseball teams, and played trombone in the band. He loved his years in Royse City Boy Scouts Troop 312, and was proud to be a part of one of the oldest Boy Scout troops in Texas. During the summers he helped his dad with their farming and ranching duties.

In 1954 he met his future wife, Sharon Elizabeth Wilkerson, on a local bus going to work. Thus began a 73 year love story. They married after he returned home from serving in the Korean War, and had two children, Elaine and Grant.

Bill enlisted in the US Army and was stationed in Korea and Japan during the war. After he and Sharon married, he enrolled in North Texas State College, graduating with a BA in English.

Bill’s professional background was always in sales. He started his career selling plumbing supplies for Levy Plumbing in Dallas and learned the art of calling on customers in person. His favorite quote about making cold calls was “All they can do is tell you no—they can’t tear your clothes!”

Bill continued on to grad school at North Texas, and worked 3 jobs while he, Sharon and Elaine lived in Denton and he worked toward his master’s degree. During that time, he was hired by Christian College of the Southwest to teach English. As he was the only English teacher they had, he liked to joke that he was the Chair of the Department. Realizing that a teacher’s salary was not going be enough to support the growing family, he opened Sisk Insurance Agency, and later founded the commercial agency Innkeepers International Insurance, which he operated until the early 1990s.

After leaving the insurance industry, he bought Dallas Popcorn Distributors, and re-discovered his love of cold calling and personal interaction with his customers. Bill loved delivering popcorn to his customers almost as much he loved being paid to do it, because he truly loved getting to know them and tell them all his stories.

Although he wasn’t raised in the church of Christ, once Bill was converted he never looked back. He and Sharon shared a great love for the gospel of Christ. As newlyweds they were members at 8 th and Austin Street Church of Christ in Garland (later Austin Street). In the mid 60’s, he preached both services every Sunday for 3 or 4 years at the Royse City church of Christ while they were without a preacher. Bill and
Sharon left 8 th and Austinin 1958 to help start the Broadway Church of Christ (now Centerville Road Church) and were also instrumental in starting the Castle Drive and Rowlett Church of Christ congregations. Tremendous supporters of Christian education, they worked countless volunteer hours at both Garland Christian Elementary School in the 60’s and later on, Dallas Christian School while Elaine and Grant attended. Bill served on the board directors of Dallas Christian Schools for many years and was the chairman of the board from 1975-1978. In addition, they quietly helped financially support many missionaries and local preachers, Christian camps, and Medina Children’s Home in Bandera, Texas. Their legacy lives on in all these good works, and in the thousands of people whose lives were touched by the endeavors in
which they labored.

Bill is survived by daughter Elaine David and her husband John of Garland; son Grant of Garland; grandchildren Britain Locke (Addi), Cameron Locke, Alexa Mason (Bryan), Joey David, Scott David, Logan Sisk, Connor Cromley and Chloe Cromley and great-grandchildren Hannah Slayden, Lucas Locke, Addison David, Delilah Locke, John David, Beckham David, Eloise and Caroline Mason. He is predeceased by Sharon, his parents, Bill and Minnie Sisk, his sister in law Marilyn Patterson and his nephew Dr Scott Ervin.

Private interment will be at Rest Haven Cemetery in Rockwall, Texas.
