On July 3rd, 1997, Jeff married his childhood friend, Katherine "Kathy" Filtz. As children, they were known as the "sandbox twins" and spent much of their time fishing on Lake du Bay near Dancy, Wisconsin. Together, they raised three amazing dogs: Buddy, Shadow, and Bentley. Professionally, Jeff was self-employed in the roofing and siding business. He was known for his willingness to help others and his ability to repair anything that was broken. Jeff loved to travel to Mercer to spend weekends four-wheeling with his wife, Kathy. Always was helping his wife and niece Alyiah with their side gig.

Jeff was avid walleye fisherman and loved the outdoors.
