Holly Jo Oldag

Holly Jo Oldag passed away on September 30, 2025, surrounded by the love of her family after a long battle with cancer.

Holly was born on July 22, 1977, in Kansas City, Missouri, to Ronnie and Rosalie Oliver. During her high school years, she met the love of her life, Chad Oldag, and together they shared nearly 26 wonderful years of marriage. Their union was blessed with two children, who brought immense joy and pride to Holly’s life.

After graduating high school, Holly attended college and went on to build a successful career in administration, serving as an office manager for many years. Known for her incredible sense of humor and her warm, caring nature, Holly had a gift for making others feel valued and loved. She was the family’s planner and organizer — the one who made sure everyone was taken care of and that every detail was just right.

Holly loved attending concerts, especially New Kids on the Block, whom she saw live at least six times. Above all, she cherished spending time with her family, and nothing brought her more happiness than moments shared with her beloved granddaughter.

Holly is preceded in death by her father, Ronnie Oliver; father-in-law, John "Jack" Oldag; and sister-in-law, Julie Oldag.

Holly will be deeply missed by all and is survived by her husband Chad Oldag, children, Dalton (Katelynn) Oldag and Olivia Oldag; granddaughter, Elianna Oldag; mother, Rosalie Gillespie; brothers, Adam and Ryan Oliver; mother-in-law, Nancy Oldag and beloved pups, Hazel, Willow and Pollo.

Holly's Celebration of Life will be held on October 19th at 4:30p.m, at 3933 SW Middle Rd, Plattsburg MO. It will be an informal back yard style BBQ with food and drinks. A podium and mic are available for anyone to share their thoughts. Stay long enough as we come together to watch the sun set around 6:30p.m. in Holly's honor. Please bring a chair for yourself. In lieu of flowers, contributions may be made to The University of Kansas Cancer Center.
