Donn was a true “jack of all trades,” known for his resourcefulness and knack for fixing just about anything. He enjoyed following the Brewers, Packers, Badgers, NASCAR and dirt track racing. He especially loved following his grandsons in their sporting and school activities.

Donn is survived by his three children: Jeff (Haley) Speth, Jodi (Andrew) Hougan, and Kevin (Mallory) Speth; five beloved grandsons: Ayson, Axton, and Ayrow Speth, and Benjiman and Wesley Hougan; his mother, Joyce Speth; siblings: Debra Mitchell, Cynthia (David) Whitford, Jack (Gloria) Speth, and Lisa (Alan Walters) Speth; as well as many nieces and nephews. He was preceded in death by father, Donald Sr.
