Marilyn Stack Memorial

In Loving Memory – Marilyn Stack

Marilyn Grace Stack passed away on Saturday, November 13, 2024 after fighting a long-term illness.

Marilyn born July 10, 1956 to John and Joan Hensley in Emporia, Kansas. She joined the United States Air Force in mid-70s and she served in Germany.

Marilyn met Allen Lee Stack in 1998 and they married April 17, 1999. Marilyn helped run Allen’s business as an office manager and continued with many of these important tasks from home when her illness became too much to go into the office.

Marilyn loved gardening and was known by her family and friends as Mrs. Clean. She loved traveling in the motor home, almost as much as she loved her rescue dogs.

Marilyn is survived by her husband Allen Stack, her parents John and Joan Hensley, her sister Joanie (Darryl) Wilson, her son Justin (Ashley) Wade and his two children, Maddy and Lucas. As well as many beloved, extended family members.

In lieu of flowers the family is asking you to make a donation to The American Heart Association or The Dumb Friends League.

Marilyn was laid to rest on Friday, November 22, 2024 at For Logan National Cemetery in Denver, Colorado surrounded by her family and friends.
