Lisa Lynne Guertin

Lisa Lynne Guertin died on December 17, 2025, in Oklahoma City. She was 58.

She was born January 30, 1967, in Lawton. She grew up grounded in faith, focused on family, and always looked for ways to help others grow.

Lisa earned her degree in Business Administration from Tulsa University, with a focus in Marketing. She worked in sales and became a manager, but her real focus was on people. She took time to mentor. She built others up. That part mattered more to her than the job title ever did.

At home, Lisa’s life centered on family. She shared a strong marriage with her husband, Joe Guertin. She had three children: Garrett Hizer and his wife Annie, Gabrielle Hizer and her fiancée Keaton, and Grant Hizer. Becoming a grandmother to Phoenix brought her joy that words can't quite capture.

Lisa is survived by her brothers, Ron Hulett and his wife Betty, and Joel Hulett and his wife Ada. She also carried the memory of her parents, H.D. and Pat Hulett, and her sisters, Susan and Julie, who passed before her.

Lisa lived her faith. It shaped her choices. She was someone who showed up when it mattered. If someone needed help, she gave it. Quietly. Fully.

In her downtime, she enjoyed books, trying new things in the kitchen, and going to live music events. She never stopped learning or finding new ways to enjoy life.

She left behind a clear legacy. She loved deeply. She gave freely. She made space for others to be better.

A service will be held on December 27, 2025, at 10 a.m. at Christ Church Episcopal, 10901 South Yale.
