Adam Kristoff, 77, passed away peacefully on October 5, 2026.
Adam was born and raised in High Ridge, Missouri. As a child, he enjoyed watching his father repair watches and he was active in Boy Scouts. He was a fire house enthusiast who took great pride in being a volunteer firefighter. He married his high school sweetheart, Marilyn, and soon after he served in Vietnam. Upon returning home, he got his first job at Dynasauer Corporation, working the line making polyurethane products. He worked his way up to Plant Superintendent and retired after 46 years with the company.
Adam was most proud of his children and grandchildren. He loved being involved in all of their activities and sharing stories about each one of them. He was a gentle, kind-hearted man whose smile said it all. He loved Marilyn deeply.
Adam is survived by his devoted wife, Marilyn (nee Isbell), of 56 years; his loving children, Jeff (Kerri) Kristoff, Greg (Andréa) Kristoff and Amy Lyon; his grandchildren, Shelby Kristoff, Keaton Kristoff, Graham (Sydney) Kristoff, Avery Kristoff, Addy Lyon and Everett Lyon; sisters Jacqueline Thomas and Judy (John) Huebner; brothers and sisters-in-law, Frank (Marlene) Isbell, Brenda (Dave) Ruzicka, and Gary (Linda) Isbell; and nieces, nephews, other family, and dear friends.
He was preceded in death by his brother, John Kristoff, his parents Adam and Helen (nee Sedovic) Kristoff, niece, Nicole Thomas and brother-in-law Don Thomas.
His family finds comfort knowing he accepted Jesus Christ as his Lord and Savior and is now in His loving arms.
