Mary Sue Clark (maiden name McDonnell), 59, Olathe, KS, passed away Saturday, September 6th, 2025, at Overland Park Regional Medical Center.
Mary was born on November 13, 1965, to John (Jack) McDonnell and Rita McDonnell (Schaefer) in Minneapolis, Minnesota. Jack and Rita moved the family to Omaha, NE, when their kids were in primary school. From there, Mary graduated from Burke High School in 1984. She received her bachelor's degree from the University of Nebraska-Omaha. It was here that she would meet her future husband, Jeffery Clark, also of Omaha, NE. Jeff and Mary were married on July 9, 1994, at St Bernard’s Catholic Church. Mary started her career as an Elementary School teacher for Omaha Public Schools, and later worked in Lewisville Independence School District in Lewisville, Texas. She continued to work as a 2nd and 3rd grade teacher until the family moved to Olathe, Kansas, in 2000, where she then transferred to work for Learning Care Group.
Mary and Jeff were blessed with two sons and a daughter. They loved to share that each child was born in a different state. Tyler Daniel was born in Omaha, Nebraska; Amanda Marie, born in Lewisville, Texas; and Grant Alexander was born in Overland Park, Kansas. Tyler married Emily Grandgenett in 2021, and they welcomed their first child, Charlotte Ann Clark, in 2024. Not only did Mary have a close immediate family, but throughout all the places she lived, she had a large found family.
Mary was always doing things with her family and friends. Between going to friends' houses for wine, golf with the gals, visiting family all over, going on dog walks, and shopping dates, she was constantly booked and blessed. It would be rare to find Mary without any plans for the weekend. Even this month, Mary was planning on being in Omaha 4 weeks in a row, and was especially looking forward to her Granddaughter’s first birthday in a few weeks.
Mary is preceded in death by her husband, Jeff, and her parents, Jack and Rita, as well as her mother-in-law, Theresa Clark. She is survived by her son Tyler (Emily), daughter Amanda, son Grant, granddaughter Charlotte, father-in-law Al Clark, sister Patty Bain (Kevin), brother Tom McDonnell (Rene), 13 nieces and nephews, and numerous family and friends.
