Nancy Irene Sittner, beloved mother, grandmother, wife, sister, aunt, and friend, passed away quietly on December 27, 2025, at Intermountain Health in Billings, Montana. She was surrounded by her loving family and friends, held in care, faith, and deep love.
Nancy was born in Worland, Wyoming, and attended Worland High School from 1964–1966. After her family moved to Salmon Arm, British Columbia, she completed her education at Salmon Arm Senior Secondary School, graduating with the Class of 1968.
Guided by a lifelong calling to care for others, Nancy earned her Licensed Practical Nurse (LPN) license in 1971 from Weber State University in Ogden, Utah. Before graduating, she met John Miller, and they were married in July of 1971 in Worland, Wyoming. Together they made their home in Billings, Montana, where they raised three daughters: Brandi (born 1977), Jennifer (born 1979), and Brooke (born 1981).
Nancy devoted most of her working life to nursing, stepping away during her children’s earliest years to be fully present at home. During that time, she ran an in-home daycare, caring for many children with the same warmth and attentiveness she gave her own family. She later returned to nursing and also volunteered for many years brailling documents for people who are blind—quiet, meaningful service that reflected her generous heart.
For the last 28 years, Nancy was married to John Sittner, with whom she shared a home in Billings, Montana. In her final days, their shared focus was on love, care, and offering one another comfort and farewell.
Nancy deeply valued time with family and made it a priority throughout her life. She was intentional about staying close to her children and especially delighted in her grandchildren—Ethan and Mason Satko, and Jovanna Carpenter—taking great joy in being part of their lives. Nancy and Brooke made many trips to the Spokane, WA area each year to visit Brandi and Jenni’s families, play many games, bowl, watch a jaw-droppingly bad scary movie, and attend as many grandchildren’s performances and games as possible.
Nancy maintained a warm and respectful relationship with her former husband, John Miller, and his wife, Connie, and deeply valued the time spent together with their extended family, including shared holidays and gatherings.
She also prioritized visits with her siblings and their families, traveling often to maintain those close bonds. Nancy cherished time at the family farm in Saskatchewan, Canada, visiting her sister Carol Lutherand her husband Bill Luther. One of her favorite memories was riding in the tractor with Bill—simple moments that brought her great happiness. She made many meaningful trips to Arizona to visit her brother David George and his wife Beth George, and to Idaho to spend time with her sister Marie Melton and her husband Kenny Melton, always treasuring the opportunity to be together.
Nancy and John also made regular visits to her stepdaughter, Kristi Raschke, and Kristi’s husband, Matthew Raschke, valuing the time spent together and the relationships they shared.
Games were one of Nancy’s great joys. Whether it was Phase 10, Rummikub, Yahtzee, or Uno, she played with determination, humor, and plenty of laughter. Time together always mattered more than the score—especially since she had a remarkable habit of winning.
Nancy was an active and devoted member of First Christian Church in Billings, where she volunteered many hours and found deep community. She loved music and participated as fully as possible in the church choir, finding great joy in singing with others. The annual choir camps were a particular source of happiness and connection for her. Her faith was steady and lived—shown through kindness, service, generosity, and love for others. Through the church, she was also involved with Family Promise, supporting families in need.
Nancy will be remembered for her kindness and good heart, her love of God, her tenacity at the game table, her quick sense of humor, her deep devotion to family, and for being the very best mom and grandma. She was endlessly loved and will be profoundly missed.
Nancy is survived by her loving husband, John Sittner; her daughters Brandi Carpenter (Melissa Carpenter), Jennifer Dehart (Todd Dehart), and Brooke Miller (Shawn Munter); her cherished grandchildren Ethan and Mason Satko, and Jovanna Carpenter; her stepdaughter Kristi Raschke (Matthew Raschke); her siblings David George (Beth George), Marie Melton (Kenny Melton), and Carol Luther (Bill Luther); and many beloved nieces and nephews.
Nancy often said she didn’t care for flowers—because flowers don’t last. In her honor, memorial donations may be made to Family Promise, an organization close to her heart that supports families experiencing homelessness. Donations can be made online at https://www.familypromiseyv.org/.
A gathering of family and friends to celebrate Nancy’s life will be held in the summer of 2026 at First Christian Church in Billings, Montana.
