Mark C. Willey

Mark C. Willey, age 57, passed away peacefully, surrounded by family, on Sunday, December 21, 2025, at his home in Osceola, WI.
Mark was born to parents Raymond and Karen (Kluss) Willey on November 19, 1968, in St. Croix Falls, WI. He was baptized and confirmed at Zion Lutheran Church in East Farmington. Mark attended Cedar Lake School in his earlier years, and then attended Osceola school, graduating from Osceola High School in 1987. During his school years, he was involved in wrestling and FFA and worked on several local farms.
Upon graduating, Mark joined his father and began working at F&A Dairy Products in Dresser, WI. During this time he continued to work on farms, both at Traiser's and on his own land near his cabin in McKinley, WI. When F&A was sold to Saputo in 2018, Mark stayed with the company as an invaluable employee. In 2021, when Sweet Additions took over operations at the plant, they requested he remain as warehouse supervisor given his intricate knowledge of the plant.
Mark collected antique tractors and placed in multiple tractor pulls. He loved riding his side-by-side, attending country music festivals, and spending time with family and friends. Mark was always there to lend a helping hand; his robust laugh and catchphrases will be missed.
Mark is survived by his son Ryan; mother Karen; sister Robyn (Corrine); sister-in-law Melissa; nephew Brandon (Sabrina); nieces Brittany (Luke) Lindahl and Kate (Matt) Bethke; great nieces Brynn and Wynonna; great nephews Kaden, Theo, and Walker; other extended family and friends.
Mark is preceded in death by his father, Raymond; brother, Eric; grandparents, Fred and Zeatta Kluss and Thomas and Opal Willey; godparents, Irvin Kluss and Iris Harris.
Visitation will be held on Monday, December 29, 2025 at Grandstrand Funeral Home in Osceola, WI from 3:00 PM to 6:00 PM. Funeral services will be at 11:00 AM Tuesday, December 30, 2025 with visitation one hour prior to the service at Zion Lutheran Church in East Farmington, WI.
