Kim Williamson-Andresen, 71, passed away on October 4, 2026, at her home in Mesa, Arizona. She was a loving wife and a devoted mother. She was a great lady and is sorely missed by all that knew and loved her.

Born in Chicago in 1955, Kim was a life-long Cubs fan and was excited to see her beloved Cubbies win the World Series in 2016. She loved going to casinos and frequently came home a winner. She was a voracious book reader and loved watching movies. Kim also liked to travel. Her high point was a family vacation to Italy in 2006. She enjoyed driving her Mazda Miata MX-5 after years of having to drive "mommy cars".

Kim worked as a Procurement Manager for Ineos, first in Naperville, IL and then remotely from Arizona.

She is survived by her husband, Robert, her sons, Robert H. Andresen and Michael W. Andresen; and her sister, Wendy Cline. She was preceded in death by her older sister, Pam Heaney.
