Leslie Jo Koeser of Green Bay, Wisconsin, peacefully passed away on Wednesday, October 9, 2024 at the age of 66 years. Leslie was born in Green Bay on February 24, 1958 to the late Gordon and Barbara Liesh.

Leslie had a great work ethic and was never late, even if it led to a run-in with a state trooper on the road. Leslie was the mom of the neighborhood, organizing get togethers, cookouts, and anything else, just to spend quality time with family. She was a hard working woman who did all she could to provide for her children. Family is what meant the most to her, especially her grandchildren. Nothing made her happier. In her free time, she recently found a passion in creating arts and crafts.

Leslie is survived by her children, Stephanie (Michael Thurber) Tomajcik, Gordon Liesch, and John Liesch; grandchildren, Mila Thurber and Leia Thurber; siblings, Laureen (David) Schneider, David (Amy) Liesch, Daniel (Bonnie) Liesch, Jody (Daniel) Unsinn; along with numerous cousins, nieces, nephews and friends.
