William "Bill" Joseph Sweeney

William Joseph (Bill) Sweeney, 75, passed away peacefully at his home in Owasso, Oklahoma on February 19, 2026. He was born in Tulsa, Oklahoma on August 10, 1950, the third son of Joseph W. and Frances (Ferguson) Sweeney. Bill grew up with three brothers on the family farm west of Oologah. He attended school at Oologah, Northeastern A&M (NEO) at Miami and earned a Bachelor of Science degree in math and computer science from Oklahoma State University (OSU) in Stillwater, Oklahoma, in 1972. Bill met his future wife, Wilberta Grimes, at NEO and they later married while at OSU. While at OSU, Bill worked part-time at the Stillwater National Bank thus beginning his life's career in banking. He held positions with the First National Bank in Oklahoma City and the Bank of Oklahoma in Tulsa. During his tenure with the First National Bank, Bill was instrumental in developing the first automatic teller system marketed and utilized throughout many banking and financial institutions all across the southwest as well as in several foreign countries. His expertise and responsibilities required on-site installation and personnel training all across Oklahoma, Arkansas, Colorado, Missouri and Texas. Bill later chose to move off the road and closer to home where he secured a marketing research position with the Bank of Oklahoma where he continued until retirement. Bill was a life-long sports and outdoorsman. In his early years, the farm life provided a world of opportunities for hunting, fishing, swimming, and camping. In addition, the family spent many years enjoying water sports on Grand and Oologah Lakes. Bill was an excellent southpaw baseball pitcher in little league and high school where he also played football. In later years, Bill took up snow skiing and was a past member of the Tulsa Ski Club in addition to being a certified scuba diver. His passion, however, was fishing from childhood until the end. He was a Bassmasters member and fished tournaments far and wide, never missing an opportunity to wet a hook. Bill was preceded in death by his beloved daughter, Jill Stacy; his parents Joe and Frances Sweeney and his brother Jimmy Dale Sweeney. He is survived by his Granddaughter, Harper Stacy of Oklahoma City; his brothers Dan Sweeney of Oologah and Ron Sweeney of Grand Lake; his three nieces Kim Arnold of Oilton, Shawn Sweeney of Owasso and Kelly Sweeney of Oologah; and his nephew, Corey Sweeney of Springfield, Illinois. Arrangements are entrusted to the Mowery Funeral Service, 9110 N. Garnett Road, Owasso, OK 74055. (918) 272-6244.
