A memorial celebration will be held Sunday, May 29, 2022, 1:00 p.m., at the family residence. If you would like to share memories and photos of Roger, please email them to rogernackmemories@gmail.com, as Roger's daughters will be compiling memories for his memorial. Roger was born on June 4, 1943, in Miltona, Minnesota, to Hertha and Roy Nack. His family moved to Denver, CO when he was a young boy. After graduating from Colorado Lutheran High School in 1961, he enlisted in the Army and served at Fort Fitzsimons Army Hospital in Aurora, CO. He was discharged from the Army in 1967 and then went on to attend the University of Denver. Roger met and fell in love with Cleo Young while both worked at Fitzsimons. They were married in 1969, and moved to Livingston, MT, in 1978 with their two daughters. He built the family log home with his two sons while working for the local bank that eventually became American Bank in Livingston. He was their computer programmer and systems analyst throughout his career until he retired in 2008. Roger was an active member of the Rotary Club, The Livingston Sister City Program, The Livingston Seventh Day Adventist Church and the Park County Senior Center, and served as a board member for Arrowhead School, and the Paradise Canal Water Users, among many other programs. In addition to his active community involvement, Roger enjoyed spending time with all his grandchildren, cruisin' with the top down through Yellowstone Park, riding around on the John Deere tractor, and spending time on the family land. He also taught robotics for two years on the island of Guam. Roger was loved by everyone in part because of his eternal optimism and cheerful "Good Morning!" greeting, regardless of the time of day. He loved music and shared his talents singing throughout high school, university, and in the community, playing guitar and singing at his church. He was a kind, loving and patient human who would put anyone before himself. He never wavered from his commitments and follow-through and could always be counted on. Roger will be deeply missed but never forgotten. Roger is preceded in death by his loving wife, Cleo, and his two sons, David, and Daniel Lambert. He is survived by his two daughters, Heather (Bob), and Amy (Andrew); his sister, Gloria (Bob); daughter in-law, Cindy; grandchildren Chad, Jeff, David, Sam and Althea; as well as great-grandchildren, cousins, loving family and friends.
