Doug was born on November 25, 1962 in Dubuque, Iowa to parents Bruce and Joan (Lary) Trentz of Dubuque, Iowa. He graduated from Hempstead High School in 1981, and then went on to college at Iowa State University. Doug was the Quality Assurance Manager at Loparex in Iowa City and worked with the company for 28 years.

Doug loved to bike (and had many bikes including road bikes and a fat tire bike), he completed RAGBRAI countless times and enjoyed riding the Pedaler’s Jamboree with his kids Ashley and Alex. This last Ped Jam he was also joined by Sophie and Jake. It didn’t matter if it was summer or winter, riding alone or with the many, many biking friends he had made throughout the years, Doug always enjoyed the ride. He was known to get the dance floor started, and almost always had his music turned up loud at home. Doug was a huge Iowa State Cyclone fan and had football season tickets with Alex.  He was a talented runner and hurdler in his younger years, and proved he still had it while running hurdles with Ashley once while she was in high school. He was introduced to camping and mushroom hunting by his dad, and then continued to enjoy these hobbies with his children in later years. He enjoyed growing a garden each year and was a phenomenal cook.

Doug is survived by his two children, Ashley (Jake) Trentz of Mineral Point, Alex (Sophie) Trentz of Milwaukee, his brothers Tom (Cindy) Trentz of Maquoketa, Mike Trentz of Maquoketa, Tim (Angie) Trentz of Dubuque, and Todd (Kara) Trentz of Dubuque, 9 nieces and nephews, 2 great nieces and nephews, 5 aunts, 1 uncle, as well as countless lifelong friends

He was preceded in death by his parents Bruce and Joan Trentz, uncles John Lary, Gene Lary, Bill Trentz, Bob Trentz, Mark Steingreaber, and aunt Beverly Trentz.
