Michael "Mike" Sweeney

February 1, 1944 — August 5, 2023

Lone Tree


Mike was a beautiful Colorado “Old Soul”.  He was born in San Francisco on February 1, 1944, moved to Denver at age one and became  a native Coloradoan at heart. He grew up in south Denver fishing at Washington Park and riding the bus from south Denver to north Denver at a young age to “help “ his grandfather who owned Murphy Mahoney Chevrolet. It was there that MIke developed his love for cars and his ability to tinker with them. 

After graduating from Mullen High School in 1962, he attended Colorado State University and graduated in 1967 with a degree in Industrial Construction Management. He worked in Omaha for several years and then returned to Colorado where he took a couple of years off to play in Aspen and the Roaring Fork Valley. Mike returned to reality  as a project manager on large commercial buildings in Denver. Mike and I met in 1971 and married in 1975. 

Our biggest adventures started a year later when we moved to Glenwood Springs to open an auto salvage yard.  Mike had a good head for business, and it soon prospered. Both Brian and Paul were born in Glenwood, and we  lived there for 10 years before moving back to Denver to purchase another business which included the land. Many of our most treasured, lifetime memories happened during those ten short years in Glenwood. We had so many great friends and shared so many crazy adventures together.  We never stopped remembering and missing our time in the Springs.

Tiring of the demands of the auto salvage business in 1998, Mike decided to repurpose the land to mini storage units and RV storage. This was a great idea as it gave him more time and freedom to pursue his hobbies like furniture building, license plate collecting and traveling.  

While Mike’s health began to decline in 2013, we still continued to travel, especially to Mexico, and play with our six grandchildren. He also continued working on projects as he never could stand being idle. My dear soulmate passed away peacefully on Saturday, August 5, 2023.  Although he will be dearly missed, he is off to his new adventure and will remain forever in our hearts. 

Mike is survived by his wife, Cindy; his son, Brian and wife, Megan, and his grandchildren Liam, Charlie and Ellie; Mike’s son, Paul and wife, Laura, and his grandchildren Lucas, Anna Claire, and Carson; Mike’s sisters: Meg and Kathleen, brother, Patrick, and numerous cousins and other  family members.
