Dennis Hatch Rosier passed away peacefully at his home surrounded by family on Wednesday, February 9, 2022. Dennis was born in Woods Cross, Utah, on October 30, 1937, to William Wallace Rosier and Lillian Hatch Rosier. He was their fourth child but was their oldest living son due to the childhood deaths of his two older brothers.

He was blessed with the loyal friendship of four brothers and three sisters throughout his life. The family was close and enjoyed working and playing together. Dennis was known for his stories of life at Holbrook and Smoot Dairies in Davis County, Meadow View Ranch in Chester (Sanpete County) and other locations where the family lived and farmed. Dennis especially enjoyed working on the farms with his father and brothers. The experiences that they shared were often challenging but special to them because of the love they felt for each other.

In high school, he discovered a love for woodworking, and later at Snow College he found his gift for all things mechanical. Dennis finished his education at Utah State University where he earned a degree in automotive technology. He went on to enjoy a distinguished and satisfying career teaching high school automotive mechanics.

Dennis served as a missionary for the Church of Jesus Christ of Latter-day Saints in the Southern Australia Mission, laboring in the cities of Melbourne, Ballarat and Adelaide. He enjoyed serving the Australian people in teaching the gospel and by blessing lives on occasion through his mechanical abilities. These experiences also strengthened his own conversion to the gospel and deepened his commitment as a disciple of Jesus Christ.

Dennis married Iris Belliston in the Logan Temple on December 27, 1962. To them were born ten children, Richard (Kathleen), Robert (Karen), Julie (Dave) Thacker, Ronald (Shelly), Ryan (Jill), Stephanie (Bart) Mortensen, Stephen (Ann), Kathryn (Matthew) Robbins, Mary Ellen, and Karen (Jeff) Peterson.

Providing for his growing family was a constant concern for Dennis. One of the most pressing issues during the early years was enlarging the size of the house. To that end he embarked on a remodeling project to more than double their living space. With help from family, friends, and children he managed to finish rooms as they were needed over the ensuing years. In the process, the older children had opportunities to work closely with their dad, much as he had done with his father on the farm. Much thanks to a faithful home teacher, Norman Connelly, who during the early phase of this project selflessly helped Dennis night after night to finish the roof before snow came. They finished shingling around midnight one Saturday in late November and there was snow on the roof in the morning!

Dennis and Iris were devoted parents. Chores were a given and work was expected. Love and attention were also part of family life. During family home evenings every child was invited to perform or participate in their own way prior to a gospel-oriented lesson presented by Dennis or Iris, followed by a special treat afterwards. Though execution of these evenings was often less than hoped for, they persisted, laying a foundation of love between all family members and joy in being together. Fruits of their vigilant labors in raising their children have been abundant as Dennis and Iris have enjoyed their posterity of 43 grandchildren and currently 6 great- grandchildren. When the grandchildren were young, Dennis felt blessed to have what he referred to as his own Primary!

For 35 years Mr. Rosier taught auto mechanics at Davis High School in Kaysville, during which time his influence helped many young people to discover interests in and learn foundational skills required for automobile repair many years, Chrysler corporation, and later Ford, sponsored a contest for high school student technicians, working as two-man teams, to diagnose and repair a current model vehicle of that year. Dennis’ teams regularly won that contest at the state level, and some went on to place high in the national finals as well. Several of his students became professional auto technicians or made their careers in related fields, and credit Mr. Rosier as a significant influence in choosing their professions.

Dennis loved teaching and found much satisfaction in seeing his students advance in skill and ability. He likely would have taught forever had not heart difficulties gotten in the way. A heart attack in his early sixties caused early retirement, and his personal challenge thereafter was battling heart disease. Eventually, he received a left ventricular assist device (LVAD), essentially an electric pump implanted below the heart to send blood to the body, which added nearly a decade to this life. He enjoyed interfacing with the professionals in the LVAD program at the IMC hospital in Murray and was grateful for their services. He also found satisfaction in helping others learn about LVADs, and especially in encouraging his “LVAD Brothers” as they learned how to live with their new devices. The family extends special thanks to the Intermountain Medical Center LVAD professionals and to all who have helped Dennis through his struggle with heart disease over the years. We are also very appreciative to the hospice team who cared for him.

Dennis was preceded in death by his parents, older brothers Dale and William, younger brother Bill, and daughter Mary Ellen. He is survived by his wife and family and siblings Jean, Gary (Dixie), John (Sue), Linda, David and Lauri (Steven) Clark and sister-in-law Diane.

Funeral services will be held on Saturday, February 19, 2022 at 12:00 p.m. at the Rock Chapel on Center St. and 200 East in Kaysville, Utah Friends may visit with family Friday from 6 to 8 p.m. at Lindquist’s Kaysville Mortuary, 400 N.

Rest In Peace Mr. Rosier. I was fortunate to be nominated by Mr. Rosier to compete in the Plymouth AAA troubleshooting contest 1989. His teaching and guidance inspired me with confidence to remove barriers and accomplish great things. God bless you and your family.
