Dennis was born July 10th, 1963 to Elvira Donnice Mahto in Pierre, South Dakota. He was a part of a large family, his siblings: Sandra, George 'Buff', Jeff, Blaine, Joan, David, Laurette, Georgia, and Denise. He grew up in Wolf Point, Montana, and in Pierre, SD, moving often with his family. He had a love for traveling, and a passion to work with his hands, such as drawing and carpentry. Despite his age at the time, he spent the majority of his youth taking care of his grandparents, Leslie and Alma Mahto in Pierre. He then moved to Winner and married Nancy Antoine on September 2, 1989. He had three children, Noland, Dayle, and Aarin. During these early years, he battled diabetes, which would develop into kidney disease much later in life. Dennis would often travel with his father-in-law, Roger; for work. Doing jobs like construction and working on houses. He also worked as a bus driver for a time at the Lame Deer Head Start Center. His bus code name was 'The Rubber Duck'. He liked to jam out to rock music with the kids. Dennis was a part of bowling leagues during the fall and winter and played softball on his Waynes Auto's team in the summer. Both of which he excelled at. It wasn't long into those years that he discovered he had leukemia and began to lose his sight shortly after. Dennis withdrew from work around 2004 and remained at home with his family and grandchildren. He developed many lifelong friendships and remained active despite everything he endured. Dennis was always noticeable due to his trademark Vikings hat and sunglasses. Every weekend he was always looking forward to the next football game. His favorite activity was to sit out in his backyard with a cold one in the sun; with his radio while his family and grandchildren played nearby. Dennis loved all his family near and far. Toward the fall of this year, Dennis contracted Covid-19, which he managed to beat. After his recovery, he spent the remainder of his days at home with family till his health took a turn. He fought till the very end for all of those that he loved and those who loved him. Now he is finally at rest and at peace. He is preceded in death by his mother Donnice; his siblings Joan Wetsit, Laurette Wetsit, Denise Zimmer, George 'Buff' Wetsit, and David Wetsit; his grandparents Leslie and Alma (Wells) Mahto and Sydney and Alma Bad Moccasin; his father-in-law Dr. Roger Milk; his uncle Leslie Mahto Jr and uncle Norman Wilson; his nieces Sayra Mahto, Daveau and Mariah Azure; his grandaughter Jozlyn Turney, and his nephews Elijah Zimmer; Mason and Nathaniel Wetsit.

We would like to thank his doctor, Dr. Snavely, and those who assisted in his care. Dennis was a very strong man who always confronted a problem head-on and full of confidence. He was very proud of all his long battles and all the hardships he overcame in his life. Dennis had an amazing sense of humor and seemed to always have a joke ready. Dennis always lent a hand to those who needed him and never judged a situation. There was nothing he wouldn't do for his family and friends. He was a determined and passionate man who wouldn't let anything stand in his way. Dennis will always be remembered, sorely missed, and greatly loved forever.
