Jeffrey "Jeff" Allen Sadoski, age 69 of Fox Lake, was called home to Jesus on Thursday, December 18, 2025, at Randolph Health Services.

Jeff was born in Beaver Dam on September 16, 1956, the son of Gervis and Beverly (Born) Sadoski. In Jeff's younger years, he climbed poles to install cable alongside his brother Greg. He spent many years enjoying hunting with all his brothers, sisters and cousins. He loved to drive motorcycles and jacked-up cars with no lights - always way too fast for his mother's heart to take. He enjoyed shaking dice, and tipping a few with family and friends. He later found that working on cars was easier than climbing poles for a living. He cherished celebrating Penny's and his birthdays at the cottage in Ladysmith. Jeff loved his family deeply; he was the "fun uncle" and cared dearly for his sons, daughter and grandchildren.

Jeff is survived by his better half and the love of his life Penny Schumann; sons, Nolan Boomsma, Josh Lessor, and David (Ashley Bladl) Lessor; daughter, Ashley Lessor; numerous grandchildren; and one great-grandchild. He is further survived by his siblings, Pat Rahm, James Scott (Tracy), Giles, and Denise Warner (Paul), as well as many nieces, nephews, other relatives, and friends.

Jeff was reunited in death with his loving parents; his brothers, Steve and twin brother, Greg; his nephews, Travis Sadoski, Chris Sadoski, and Brandon Witthun; Richard Holch, the longtime partner of his sister, Patsy; and many relatives close to his heart.

In honoring Jeff's wishes, a celebration of his life will be held at a later date. Details will be announced by the family once finalized.

Cornerstone Funeral & Cremation Services is honored to be serving the family.
