Mattes

Daniel G. Mattes passed away peacefully, surrounded by his loving family, on November 5, 2026, at the age of 93.

Dan was the beloved husband of Sylvia, with whom he shared 32 wonderful years. He was a devoted and loving father to Dennis (Julie) Mattes and Deanna (Patrick) Schmidt; a loving stepfather to Peter Bandoske and Keith Bandoske; and a proud grandfather of ten grandchildren and 8 step grandchildren. 

He was preceded in death by his first wife, Donna Mattes; his dearly loved children, Denise Brown and Daniel “Danny”Mattes, Jr.; and by his stepson Ned (Carol) Bandoske, whose memories remained a lasting source of love and strength throughout his life. He is further survived by many cherished relatives and dear friends.

Dan proudly served in the United States Army. He began his career with Mitchell Novelty Co., a family-owned business that provided Juke Boxes, Amusement Games, Pool Tables, and Dart Machines throughout the greater Milwaukee area. Through hard work, determination, and an entrepreneurial spirit, he went on to own and operate several successful automotive dealerships throughout southeastern Wisconsin.

Above all else, Dan was the rock of his family. Family meant everything to him, and he took great pride in the love, support, and guidance he provided throughout his life. His strength, generosity, and unwavering devotion to those he loved will forever be remembered and treasured.
