Dennis LeRoy Mathson

December 20, 1950 — January 22, 2023


Dennis LeRoy Mathson, 72, passed away somewhat suddenly after a brief illness at a Missoula hospital on Sunday, January 22, 2023. He went peacefully, surrounded by family and friends.

Dennis truly lived life to the fullest! He was a loving dad, grandpa, brother, son, husband, and friend. He was selfless, loving, and kind to everyone around him.

He was born with a twin, Dale “Curt”, to Eddie and Donna Mathson in Great Falls, MT. Growing up, he and Dale played baseball, music, and were in a band with friends in high school. He graduated from GFHS in 1969, served in the U.S. Air Force, attended MSU Northern receiving an Associate Degree in Diesel Technology, and went on to receive a Refrigeration Certification from Thermo King in Minneapolis.

Dennis worked 41 years as a Civilian HVAC Technician at Malmstrom Air Force Base in Great Falls. He also operated a side business, Quality Cooling, for about 10 years. Remaining active, Dennis continued working part-time during retirement.

He and his former wife Mimi, married for 34 years, lovingly raised their two sons, and remained friends. Dennis was a coach in multiple sports for both of his sons, was involved in Boy Scouts with them, and encouraged them to pursue their dreams. As a member of the Catholic Church, he was active in High School Searches, Cursillo, and music ministry for many years.

Some of Dad’s many interests and hobbies included baseball, softball, fishing, pool (billiards), music, dancing, karaoke, guitar playing, and mechanics. He was a noted pool player, never being far from his cue. He played in multiple leagues and he and his son Scott loved playing pool and spending time together almost weekly these past years while both living in Missoula. Dennis loved visiting his son Mark and his family. He brought presents, donuts, and watched his grandchildren play sports; also teaching them how to play pool.

Dennis is survived by his two sons and their families, Mark (Jennifer) and grandchildren, and Scott (Michelle); twin brother Dale “Curt” (Carol); two sisters Debbie and Diane (Anthony); former wife Mimi (Glen); nieces and nephews; his companion Yvonne Hall; and many friends. He is dearly missed by all who knew and loved him.

In Dennis’ honor, please do a random act of kindness as he so often did.
