Jason A. Maki

Jason A. Maki, age 51, of Weston, passed away on Tuesday, April 28, 2026, at the Aspirus Wausau Hospital. He was born on September 15, 1974, in Crystal Falls, MI. He was the son of The Late JoAnn and Ken Kosky. Jason attended and graduated from DC Everest High School, and later Northcentral Technical College in Wausau, WI. He married Raechel Miller on July 29, 2006. They later divorced but remained close. She survives.

Jason became the owner of K&S Fuel Injection after the passing of his father. He took great pride in the business and enjoyed running it with the help of his family, especially his brother, Mike, for the past 20 years. 

He was incredibly proud of his son, Carter, who was his true pride and joy. They loved a good movie together and laughs while playing a game of Pinball. He had a love for animals, both big and small, and the family had many cats and dogs over the years. Jason was always willing to help friends and family with fundraising, charitable causes and supporting his community. His generous spirit was evident wherever he went. You always knew when Jason entered the room from his distinct voice and infectious laugh. 

Jason looked forward to cheering on the Green Bay Packers, Milwaukee Brewers and Wisconsin Badgers with his friends and family. He enjoyed his visits to the U.P. and never passed by a pastry shop without stopping. He loved all the aspects of diesel performance and spent his entire career working in the industry he enjoyed so much. Jason will be missed dearly and remembered fondly.

Jason leaves behind his beloved son: Carter Maki of Madison, his former spouse and mother of his child: Raechel Miller of Rothschild, sisters: Terri Kosky (Tom Brandt) of Shawano and Shannon (“Bear”) Bowe of Marathon, brother: Michael (Nici) Kosky of Weston, and many nieces & nephews whom all loved their Uncle Jason. He will be deeply missed by many close friends, who were a second family to Jason over many years. His absence in the lives of his family and those closest to him will be enormous.
