James “Jim” Steinberger, 79, of Greenleaf, Wisconsin, passed away peacefully on October 8, 2026. Jim was born on November 14, 1946, to the late Raymond and Lucille (Forst) Steinberger. He graduated from Denmark High School in 1965.

Following graduation, he served in the U.S. Navy aboard the USS Vermillion (AKA-107) from September 6, 1966, until September 6, 1968.

Turner (CG-20). He was a member of American Legion Post 436 in Wrightstown, where he served as sergeant-at-arms, vice-chair, and a member of the color guard. He was also a proud member of the Knights of Columbus.

Jim worked in assembly at the Ariens Company and then went on to work at Greenleaf Landscaping, the job he loved most. He loved being able to work outdoors and felt he worked for some of the most wonderful people anyone could ask for. Unfortunately, due to his age, he had to make the difficult decision to leave. He finished his working career at Modern Plastics, where he made towel dispensers found in bathrooms throughout the world. After retirement, he took a part-time job with Per-Mar Security, which gave him and Jane the opportunity to work at the Packers Stadium during home games for several years.

He married Jane Brantmeier at St. Patrick Church in Askeaton and was a member of St. Clare Parish, serving Askeaton, Greenleaf, and Wrightstown. Jim loved visiting with family and friends.

He and Jane also traveled throughout Europe and particularly enjoyed their trip to South Africa
