She is survived by her children and their partners: David (Irma) Luckett, Deana (An­drew) Luckett, Dani­elle (Michael) Robin­son; as well as her four stepchildren: Karen DePaoli, Kathleen (Michele) Marschall, Deborah (John) Ko­rniewicz, and Joanne (Gary) Justiniano.

She was preceded in death by her parents and her husband, John Marschall.

When Denice was just a few years old, her family moved to Kanab, Utah, where she lived until gradu­ating from high school. She then worked as a server at Wahweap, Arizona, before moving to Phoenix, Arizona, to attend beauty school. After earning her cos­metology license, she married Lawrence Luckett and remained in Phoenix, where she devoted herself to be­ing a homemaker and raising their three children.

Following her di­vorce from Lawrence, Denice and her daugh­ters moved to Kanab, where she served as a personal assistant to the Project Director of Global Explorations, a company involved in treasure-hunting expeditions. In one as­signment, she assisted with the environmen­tal study at Victorio Peak, a well-known site within the White Sands Missile Range in New Mexico. She also worked in the front office of the Red Hills Best Western, where she met John Marschall, whom she later married. The couple moved to Kent, Connecticut, for three years, where Denice worked at a bed-and-breakfast. They eventually returned to Kanab, where she worked at Denny’s Wigwam for several years. Later, they re­tired to St. George, Utah, where they en­joyed traveling, spend­ing time with family and loved ones.

Denice was raised around cattle ranch­ing and thoroughbred horse racing. She loved the outdoors and was a tomboy at heart. One of her favorite stories to tell was about being one of the first students in her class to own a car - a brown ragtop 1953 Chevrolet convertible with a manual gear shift and no seatbelts. Because the gas gauge didn’t work, she filled up frequently after cruising Kanab’s Main Street to avoid running out of gas. Fortunately, her father owned a mobile gas station and gave her a small dis­count. He even placed a donation jar on the counter to help fund her fuel expenses.

A member of The Church of Jesus Christ of Latter-day Saints, Denice lived by the Christian values that guided her through­out her life. She was friendly, loving, gener­ous and always helped others in need. Her high school yearbook described her as hav­ing: “A jolly disposition and a carefree mind; a happier girl you will never find.” Those words remained true throughout her life.

She loved her fam­ily and friends deeply and cherished every opportunity to spend time with them, in­cluding traveling to destinations around the world. One of her favorite traditions was reserving rooms at the Best Western in Kanab each summer so family members could gather for a special weekend together. She also enjoyed traveling to Payson, Arizona, to spend time at the Luckett family cabin, where many treasured memories were made. Denice enjoyed walk­ing five miles each morning with her walking group, going to the gym, reading, lunch dates and watch­ing crime series.

During the last few years of her life, Denice was diagnosed with mild dementia. She struggled with the realization of the dis­ease and worked hard to overcome its effects by moving into a retire­ment center, staying active, socializing and keeping busy. As the disease progressed, she eventually moved into a memory care facility. In her final months, she received hospice care focused on her comfort and well-being. She was surrounded by family, friends, and compas­sionate caregivers at the time of her passing.

Funeral services will be held on Friday, July 3, 2026, at 10 a.m., at Mosdell Mortuary. A burial will follow at the Kanab Cemetery.

The family wishes to express their love and appreciation for the kindness shown during this time. In lieu of flowers, donations may be made to the Alzheimer’s Association Utah Chapter to support Alzheimer’s and dementia programs, support groups and research.
