Jo Dona (Jo D) Duncan Armstrong passed away at home on Monday, April 21, 2025 at the age of 58 after an extended battle against cancer, a battle she fought with strength and grace and without complaints. Born on July 20, 1966, Jo D grew up in Noel, Missouri, a small town in the southwest corner of the state. There she was a gifted athlete, excelling in both basketball and golf in high school. As a point guard on the basketball team, she was on the 1983 team that won the Missouri State Class 3A Girls Basketball title. This led to her Class of 2022 induction into the Missouri Sports Hall of Fame as part of the 1980- 1983 Era of McDonald County High School Girls Basketball.

As a golfer, in 1984 Jo D joined the McDonald County High School golf team, which had just been added to the curriculum. Not only was she the only girl on the team, she was the only girl in the Big Six Conference on a varsity boys’ team. Her golfing skills landed her a scholarship at Southwest Missouri State University. Upon graduating, Jo D spent time testing her skills as a professional golfer but
ultimately decided to accept the position of Director of Golf Instruction at Norwood Hills Country Club in St. Louis, MO, in 2000, a position she held for nearly 25 years. In addition to giving individual and group golf lessons, she developed and managed a successful junior golf program and also helped nurture and grow the Ladies Evening Golf Social (LEGS) group.

Jo D competed in the World Long Drive Championship several times. Her best performance was finishing 2nd in 2001. She was also a competitor on the 2005 golf reality show, The Big Break V, which was filmed on Oahu, HI.

Jo D was a devoted wife as well as a loving mother to “fur-babies,” Tripp (Westie) and Macey (Tabby). Jo D is survived by her adoring husband of 17 years, Scott Armstrong, her mother Sharon Duncan, her brother Mark (Becky) Duncan, her sister DeeAnna Duncan and 3 nephews and 2 nieces. She was preceded in death by her father Donald Duncan.

Jo D’s lasting legacy will be the passion she had for golf and for life, both of which she tried to pass on to each and every one of her students regardless of their age or skill level. We Love You and will Miss You. A Celebration of Life will be held on May 18, 2025 from 1pm-4pm at Norwood Hills Country Club, 1 Norwood Hills Country Club Drive, St. Louis, MO 63121

In lieu of flowers, memorial contributions may be made in the name of Jo D Armstrong to Evelyn’s House, in care of The Foundation for Barnes-Jewish Hospital; 1001 Highlands Plaza Drive West, Suite 140; St. Louis, MO, 63110.
