Dianne Kay Thomsen

April 3, 1946 — January 1, 2023

Dianne passed away peacefully on Sunday January 1, 2023 with her husband Terry of 57 years by her side.  
Dianne was born on April 3, 1946 to Marion Lee Baker and Shirley May Manker Baker in Denver, CO.  She was the 1st born of 5 children.  In 1959 her family mover to Glenwood Springs, CO.  Dianne attended school and graduated from Glenwood Springs High School in 1964.  She then moved to Denver to attend cosmetology school.  She met her soulmate and lover of her life, Terry Thomsen in Denver.  They married Nov. 7, 1965 in Glenwood Springs.
Terry joined the Army shortly after their marriage, which took them to California.  After basic training and a short time in California, they were off to Anchorage, Alaska.
Their first child Lonnie as born in Anchorage in 1967.  After serving 3 years in Alaska they moved back to the lower 48 and first settled in Denver, CO.  They made their permanent home in Cheyenne, WY, where their 2nd child, Lisa was born in 1973.  While Diane was raising their 2 children, she worked in a daycare facility in Cheyenne, but her first and foremost priority was being a loving and devoted wife and mother.  
She and Terry opened their muffler shop, Perfection Muffler in Cheyenne in 1987, where they worked together until her illness was diagnosed in Nov. 2022, forcing them to close the business after 35 years. They were an extremely hard working team and took great pride in taking only the best care of their clients.  In addition they enjoyed working together and supporting each other.  They were inseparable.  With running a business together with no employees it did not allow them much vacation time.  But, when they did get away it was to go visit their children and grandchildren in Denver and Holton, KS, as well as other family members.  They also on occasion were able to get away to visit South Dakota and Cody, WY, their favorite places to relax. In addition to traveling to visit family they enjoyed long car rides on the weekends.
