Dennis Pierce

July 24, 1945 — October 22, 2023


Dennis Michael Pierce, age 78, passed away on October 22, 2023, in Cheyenne, Wyoming, surrounded by his loving family after a long and courageous battle with Chronic Obstructive Pulmonary Disease (COPD). He is survived by his only child, Erin [Barry] Benedict, and his two cherished grandchildren, Dylan Hoock and Sierra [Damian] Olaveson. He is preceded in death by his wife of 50 years, Joan, and his infant son, Dylan.

Dennis was born in Rochester, MN to Dennis and Ruth [Thedens] Pierce. He grew up with his older sister, Marilyn [James] Laudon, his younger brothers, Kenneth Pierce, and Paul [Arlene] Pierce.  After graduation from Minnesota State’s Electrical Lineworker Technology program, he went to work for Teleleckt, Rochester Public Service, and People’s Cooperative Power Association.  

Denny found his true passion and dedicated his career to ensuring that lights stayed on and power flowed when he worked as a lineman for Montana Power Company in Great Falls, MT and subsequently, the town manager in Choteau, MT.  At the end of his career, he served as a safety manager for MJ Electric, where he traveled the country ensuring the well-being of his colleagues. For the last two years of his life, Dennis lived with his daughter, Erin, where they enjoyed doing crossword puzzles together and playing cards.

Denny had a deep passion for hunting and fishing. He would spend countless hours on the water and was always excited for opening day. He found joy in passing on his love for hunting and fishing to his family and friends, especially his daughter, his nephews, and his grandchildren. You never had to ask him if he wanted to go fishing because the answer would always be, “Yes!”  His love for fishing was only surpassed by his love for his family and friends. He was known for his kindness and generosity, always willing to lend a helping hand, a listening ear, and probably a cold beer to anyone in need. His infectious sense of humor could light up any room, and he had a talent for bringing laughter to those around him.

His home was open to all, a place where memories were made, stories were shared, and laughter echoed through the late-night hours. Dennis will be remembered for his warm heart, his boundless generosity, and the way he made everyone feel welcome. He adored his two grandchildren, Dylan and Sierra, and their love for him was equally deep and enduring.  Denny touched the lives of many and will be deeply missed by all who had the privilege of knowing him. His legacy of love, laughter, and kindness will continue to live on in the hearts of those he leaves behind.
