TERRENCE âTERRYâ JOHN THEISEN
After a long battle with Parkinsonâs Disease, COPD, and a short battle with Covid-19, Terrence âTerryâ John Theisen died on Dec. 23, 2020, at his home at Open Arms in Belgrade, Mont.
Terry was born in Missoula, Mont., on Jan. 28, 1944, to Wilford C. and Kathryn Theresa Deegan Mellen. He and his mother moved to Virginia City, Mont., after his fatherâs sudden death. His mother then married John âCliffâ Clifford Theisen and moved to the family ranch near Belgrade in 1950. After Cliff Theisen adopted Terry, they had two more sons, Michael and Daniel Theisen. Terry enjoyed living on the ranch with his brothers and always said Cliff was the best thing that ever happened to him. He gained knowledge of ranching and farming as well as being exposed to core values.
