Karen Marie "Theis" Moore

Karen Marie Moore, 83, of Sturgeon Bay, died unexpectedly on March 12, 2026 at St. Vincent Hospital in Green Bay.

Born July 18, 1942 on the Arthur Herison Farm in the Town of Lincoln, Karen was the daughter of the late William and Mary (Herison) Theis. After graduating from Casco High School, she earned her LPN from a Green Bay vocational school and devoted her career to nursing. She cared for patients at Algoma Memorial Hospital, St. Vincent Hospital in Green Bay, and Dorchester Nursing Center in Sturgeon Bay for more than thirty years before retiring in 2020.

On April 25, 1974, Karen married Robert Leon Moore in Sturgeon Bay. A longtime member of S.S. Peter and Paul Catholic Church in Institute, she found joy in traveling, competitive horse racing alongside her husband, cooking for loved ones, and staying connected through handwritten cards and letters. She also cherished knitting, working word search puzzles, and proudly supporting her son Wayne at his many events. Her deep love for life and quiet generosity left a lasting impression on all who knew her.

She is survived by her son, Wayne (Jamie Carothers), sisters Kathryn (Larry) Berkovitz of Bellevue and Dianne (Rick) Gordon of Manitowoc, and extended family. Karen was preceded in death by her husband, Robert Moore in 2008, her parents, infant daughter Wendy, sisters Jeanette Sperber and Patricia Eckert, and brother Robert Theis.
