Karen Louise Sims (née Hampel), 79, passed away peacefully on Friday, July 12, 2025, at Delmar Gardens Creve Coeur. She was born on September 10, 1945, in Berwick, Pennsylvania.
Karen was preceded in death by her husband, Gary Sims; her father, Richard P. Hampel; her mother, Katherine D. Hampel; and her brother, Phillip Hampel.
She is survived by her son, Erik Sims (Tina); her grandson, Nathan Sims (Taylor); and her great-grandchildren, Luca and Emily. She also leaves behind her sisters, Paula Jones (the late Tim Jones) and Starr Himmel (Steve), as well as many nieces and nephews.
Karen dedicated over 30 years of her career to Monsanto before retiring. Outside of her professional life, she was a passionate dog enthusiast, serving for many years on the board of the Colonial Rottweiler Club and becoming an AKC Rottweiler show judge. She also enjoyed scrapbooking and was an avid football fan.
In lieu of flowers, the family requests donations be made to Stray Rescue of St. Louis.
A celebration of Karen’s life will be held at a later date.
I’m so sorry to hear of Karen’s passing. I worked with her at Monsanto years ago. She was always a voice of reason in chaotic situations.
I had the privilege of working under Karen’s leadership at Monsanto. She was more than a manager, she was a mentor, a guide, and a truly kind person. Her patience and encouragement helped me grow not only as a professional but also as a person. I’m grateful for everything she taught me, and I will always remember her with deep respect and appreciation. May she rest in peace.
Dear Paula,
Please know how very sorry I am to learn of the passing of your dear sister, Karen. I’ll always remember how close you were and how much she loved you. You continue to be in my thoughts and my heart. I hope we can talk soon.
With sincerest sympathy,
Janet Creath
