Wayne was born on August 18, 1957, to Michael and Katy (Dukart) Olheiser of Amidon. He grew up on the family farm along with seven siblings and learned at an early age how to work hard in the field and tend to livestock. This experience contributed to a strong work ethic throughout his life. After graduating from high school, he began working in the oilfields, a career he would dedicate himself to for the rest of his life with tremendous success.

Wayne married Lynn Schulz and together they had two children, Amy and Josh, before parting ways.

Several years later, Wayne found Simone and her daughter, Megan. Wayne and Simone were married for 25 wonderful years.

Amy’s kindness and strength, Josh’s determination and drive, Megan’s intelligence and love of education in the medical field, were sources of absolute pride for him. Wayne admired the girls’ beauty and grace and their independence as women and Josh’s sense of humor and their relationship as being true best friends. But most of his children’s success was due to the support and examples set by Wayne and his wise words of wisdom for all and the example he had shown them with his own work ethic in life. Wayne’s love for all three children was unwavering and each claimed a special place in his heart.

Wayne and Simone had many adventures but found their greatest joy at their cabin at Skunk Bay where he spent countless hours on his boat with one eye on the depth finder always waiting for that next tug on his fishing pole. He enjoyed many hours just sitting on the deck taking in the beauty of the bay. It was there he lived his best life in a place that brought him the peace and tranquility so many seek.

Wayne also spent countless hours supporting Josh’s racing career at Southwest Speedway. Whether he was in the pits or watching from the stands, it was something he was so proud to be part of.

Later in life came three grandchildren, who all in certain ways stole his heart. He loved being a grandpa!

Wayne also created and cherished many profound friendships along his journey in life, which he held very dear in his heart.

Wayne is survived by his wife, Simone; his daughter, Amy (Randy) Berry of Portland, OR, and his son, Josh (DelRae) Olheiser of Dickinson; his stepdaughter, Megan (Larry) Davis of Powell, WY, and stepson, Tye; their three grandchildren whom he loved dearly, McKenzi and Camden Olheiser and Lyvia Berry; brothers, Eugene (Brenda) of Billings, MT, and Bert (Nancy) of Damascus, OR; and sisters, Doris (Larry) Davison of Gallipolis, OH, Darlene (Jerry) Brinster of Glendive, MT, and Laverne (Ryan) Erickson of Amidon.

He was preceded in death by his parents; stepfather, Rudy Hirsch; and brothers, Richard and Arnold.
