Leisa “Renee” Monday

July 13, 1960 – September 6, 2025

Leisa “Renee” Monday passed away on September 6, 2025, after a courageous two-year battle with pancreatic cancer. She faced her illness the way she lived her life — with strength, grace, and an unshakable faith in God.

Renee was born in Clovis, New Mexico, on July 13, 1960. At age eight, her family moved to Tucumcari, New Mexico, where she grew up and graduated from high school. She went on to attend Abilene Christian University and New Mexico State University, earning a B.S. in Medical Technology in 1982.

She worked in the medical field for several years before meeting the love of her life, Michael Monday, a medical doctor. They married on May 20, 1989, and began their life together with a honeymoon in Flagstaff, Arizona. They then moved to Wichita, Kansas, where Mike completed his residency and where their first child, Kaitlin, was born. In 1992, the family moved to Montana, where they later welcomed two more children, Karly and Kaleb. Billings became their long-term home and the heart of their family life.

Renee’s greatest joy was raising her children in a loving, Christ-centered home. She was devoted to her family and poured herself into being present and involved in their lives. Whether cheering them on, guiding them in faith, or simply being there with a listening ear and warm hug, she was a steady, loving presence.

She was also deeply involved in her church family, teaching children's Bible classes, participating in women’s Bible studies, and serving wherever she was needed. She had a special love for Yellowstone Bible Camp, where she spent many summers growing in faith and fellowship with others.

Renee was a quiet encourager — faithful, dependable, and sincere. She had a strong sense of purpose and lived out her faith in both word and action. Many younger women admired her for her wisdom, humility, and example of a life fully devoted to Christ. Her impact reached far beyond her own family.

Renee is preceded in death by her parents, Robert E. and Gerry L. Johnson. She is survived by her husband of 36 years, Mike; her brothers, Robert (Paula) Johnson and Steve Johnson; her children, Kaitlin (Cameron) Olson, Karly (Trey) Dillon, and Kaleb (Lacee) Monday; and her four grandchildren: Maverick Dillon, Magnolia Dillon, Montgomery Dillon, and Rhett Olson — each of whom brought her great joy and pride.

Renee’s life was rooted in love, service, and faith. She will be deeply missed by her family, friends, and all who were blessed to know her.
