Jon George Kosiak

With deep sadness, we announce the passing of Jon George Kosiak, 82, of Bismarck, ND on September 29, 2026.

Jon was born January 31, 1944, in Port Chester, New York, the son of John and Kathleen (McNamara) Kosiak. He was raised in Port Chester, New York, Chisholm, MN, and St. Louis Park, MN.

Jon served as an altar boy from an early age for several years. He joined the United States Navy at age 17. Following his military service, he served with the Anoka County Sheriff's Department. He went on to receive his Juris Doctor degree from the University of North Dakota School of law in 1981 and was admitted to the North Dakota bar that same year.

On August 7, 1981, Jon married Sharon Bushaw at St. Mary's Catholic Church in Grand Forks North Dakota. They were blessed with three children and one grandson.

Jon's career managing nursing homes took his family to Blackduck, Minnesota, Alamogordo, New Mexico, and Jasonville, Indiana, before retiring in Bismarck, North Dakota.

Jon enjoyed traveling and family reunions. He also worked on John F. Kennedy's presidential campaign. He was a Fourth Degree member of the Knights of Columbus and proudly served as school Board president at Father James B Hay School in Alamogordo, New Mexico, which was later named St. Francis Cabrini Catholic School. He volunteered at numerous school activities and loved attending and supporting his children’s events wherever they might have been. Most of all, he enjoyed dressing in costumes for events and holidays. And he had a tie for almost anything. Jon was a Scooby Do fan forever, so many of us will always think of him when we see a SCOOB!

Jon is survived by his wife, Sharon: son, Christopher Kosiak of Columbus, Wisconsin; daughter, Megan (Bryan Farmer) of Bismark North Dakota: and grandson, Jonathan Kosiak.
