Michael George Whiteis

Michael George Whiteis died on Wednesday, September 16, 2026, at the age of 76, surrounded by family. The public obituary does not state a cause of death. Visitation was arranged for Sunday, September 20, from 5:00 to 7:00pm, with a wake at 7:00pm at Heritage Funeral Home. A Mass of Christian Burial was set for Monday, September 21, at 10:00am at Holy Spirit Catholic Church. He was preceded in death by his parents and two younger brothers, and survived by Marilyn, his children, grandchildren and great-grandchildren.

Michael George Whiteis was born on October 20, 1949, in Mason City, Iowa, the son of Obert and Ellen (Kokenogules) Whiteis. The family later made a home in Austin, Minnesota, where he grew up. Sports shaped his boyhood: he played baseball and ran track, and friends and coaches nicknamed him Wheaties because of how quickly he moved on the field. That early mix of speed and determination became part of how people remembered him for decades afterward.

Whiteis served his country in Vietnam as a Specialist 4 (SP4), Grade E4, assigned to the U.S. Army Security Agency. As a Signal Analyst he performed highly skilled work that demanded discipline and quiet courage. His service was recognized with the National Defense Service Medal and the Rifle M-16 Sharpshooter qualification. The military chapter of his life remained a point of pride for his family and a defining part of his public memorial.

After returning from service, Whiteis worked a succession of civilian jobs. The published obituary does not name a single lifelong career title, but it stresses that he never shied away from the effort needed to take care of the people he loved. Reliability and hard work, rather than public office or celebrity, were the measures by which his community knew him.

Cars were one of his great enthusiasms. Whether talking about them, tinkering with them, or simply admiring a good one, he found pleasure in the machines and in the conversations they sparked. Some of his happiest hours were spent with buddies, trading stories and laughter in the kind of camaraderie that lasts a lifetime.

Outside of work he found his greatest joy in nature. He was an avid hunter and fisherman, happiest with a rod in hand or out in the woods at sunrise. Golf was another passion: he loved the challenge of the course and especially the chance to share rounds with his grandchildren, combining sport with family time.

Whiteis was married to Marilyn for 35 years. Together they raised and remained close to five children: Amy DeVries, Tammy Julius, Scott Ahlemeier, Kevin Ahlemeier and Curt Ahlemeier. By the time of his death the family included 14 grandchildren and seven great-grandchildren, with two more expected. Relatives remembered him as someone who poured steadiness, humor and warmth into ordinary family moments.

In later years Whiteis made his home in Gettysburg, South Dakota. It was there that family gathered around him at the end of his life, and it was from that community that funeral arrangements were organized through Heritage Funeral Home and Cremation Services in Sioux Falls.

Those who wrote his memorial described a life defined by service, loyalty and love of family and the outdoors. The nickname Wheaties from his youth, his Vietnam service, his passion for cars and fishing, and the long marriage to Marilyn together sketch a portrait of a private Midwestern veteran whose public record is the affection of a large extended family.
