Janet T. Miles

It is with heavy hearts that we share the passing of our beloved wife, mother, and grandmother, Janet “Sissie” Thompson Miles, who passed away peacefully on January 28, 2026, in the same city she called home for more than 40 years at the young age of 81.

Sissie was born on December 27, 1944, in Roswell, New Mexico, where she was raised and graduated from high school. Growing up on her parents’ ranch with her two brothers shaped her early years, and she carried those roots with her throughout her life.

Sissie married James “Jim” R. Miles in their hometown of Roswell in 1966. They were proudly anticipating the celebration of their 60th wedding anniversary this October. Sissie was a vibrant woman whose fun-loving spirit endeared her to everyone she met. Because of Jim’s career, they were able to enjoy new places and make new friends along the way, living in Albuquerque, Roswell, Gallup, Denver, Colorado Springs, and finally settling in Littleton.

Along the way, she followed her independent spirit through many pursuits, including the Junior League and working at Steinmart, where she formed lifelong friendships. Always dressed to the nines, working with Mary Kay Cosmetics was more of a passion than a job. No matter what she was doing, Sissie brought energy, care, and a personal touch to everything she encountered.

Her greatest love in life was her family, especially her two sons, James and Chad. She adored them with fierce and unconditional love and took pride in every part of their lives. Time spent with family was her favorite place to be, and she also found joy in skiing, embracing the mountains and the adventure that came with them.

Sissie was known for her kindness, her fiery and infectious personality, and her ability to make people feel instantly comfortable and truly seen. She loved to talk, laugh, and connect, and she never met a stranger. Her heart was open to everyone, and her presence made the world feel a little brighter.

In addition to her beloved husband, Jim, she is survived by her son, Chad R. Miles, and her granddaughter, Charleigh Miles. She was preceded in death by her father, Robert Dan Thompson II; her brothers, Robert “Heavy Cat” Dan Thompson III and Charles “Chuck” Thompson; and her son, James R. Miles II. Sissie carried James in her heart every day after his passing and longed to be reunited with him. We take comfort in knowing that she is now at peace in his loving embrace once again.

A service celebrating Sissie’s life will be held on February 12, 2026, at 1:00 p.m. at Drinkwine Mortuary, 999 West Littleton Boulevard, Littleton, Colorado 80120.

In lieu of flowers, the family requests that donations be made in Sissie’s memory to the Colorado Shih Tzu Rescue - shihtzu.rescueme.org

Sissie will be remembered for her loving heart, joyful spirit, and the deep devotion she showed to her family. Her kindness, laughter, and genuine love for others will live on in the hearts of all who were lucky enough to know her.
