Teresa Mathieu Obituary
Teresa proudly served in the National Guard, dedicating herself to service with the same sense of responsibility she carried throughout her life. She worked as a supervisor for Control Data for a few years. She moved to Las Vegas, Nevada and later to Pleasant Grove Utah.
A deeply generous and caring person, Teresa spent many years lovingly supporting and caring for her mother. Her compassion extended to everyone around her. Above all, Teresa cherished her family and loved seeing pictures of them on her Aura. She had many friends at Pleasant Grove Senior Center and loved playing cards Knock Rummy and Kings Corner with her close friends Teri and Nannette.
She will be remembered for her warmth and loving nature.
Teri is preceded in death by her parents Henry Feilen and Ann McFate and sister Debbie Parker.
She is survived by her brothers Ken (Pam) Feilen and Randy (Amy) Feilen. Nieces and nephews Ken (Stacy) Feilen, Gretchen (Andy) Rachuy, Jacob Feilen and Sydney Feilen. Great nieces and nephews Brooklyn, Max, and Zac Feilen.
A special thank you to Holace and Lisa for taking care of Teri when family could not be there.
A memorial service will be held, Thursday, January 29, 2026 at 1:30 pm at the Pleasant Grove Senior Center, 242 West 200 South, Pleasant Grove, Utah. Snacks and Coffee will be served.
