Jeffrey (Lloyd) Glen Landeau, 69, passed away peacefully on June 20, 2026.

Jeff was born on August 25, 1956, in Cudahy, Wisconsin, to Lloyd and Glenda (Mauer) Landeau. He built a life centered on hard work, family, friendship, and helping others. Jeff worked for Keller Structures and Appleton Papers before pursuing his entrepreneurial spirit and founding Landeau Concrete & Construction, where he took pride in building and creating for others.

Jeff had a lifelong love of hunting and treasured spending time at the family cabin in the North Woods. As a young boy, many of his fondest memories were made at Grandpa Mauer's "Camp Winchester," where he enjoyed hunting, fishing, and heading out on his grandfather's charter boat. He found great satisfaction putzing in his shop, fixing things, building projects, and lending a helping hand to anyone in need.

One of Jeff's favorite daily traditions was happy hour in his shop, surrounded by friends and family, with his loyal companion, Ozzie, faithfully at his side. He will be remembered for his generous heart, willingness to help others, and the countless memories shared with those he loved.

Jeff was preceded in death by his parents, Lloyd and Glenda (Mauer) Landeau; his grandparents, Lloyd and Marcella (Moeller) Landeau and Glen and Bernice (Jerebek) Mauer; his uncle, Douglas Landeau; his brother-in-law, Kevin Propson; his nephew, Dillon Landeau; and his niece, Rebecca Verbeten.

He is survived by his fiancée, Diane Zolkoske; his brothers, Rick (Mary) Landeau and Michael (Kelli) Landeau; his sisters, Michelle (Bruce) Koehler, Lisa (Terry) Verbeten, Tracey (Joseph) Krol, and Lynn Propson; his Aunt Beverly Landeau; and many nieces, nephews, extended family members, and dear friends. He is also survived by Diane's family, who lovingly welcomed Jeff as one of their own: Charles (Connie) Zolkoske, Paul Zolkoske, Joseph (Judy) Zolkoske, Patty Ray, Dennis (Ann) Zolkoske, and Michelle Zolkoske.

A Celebration of Life will be held on Saturday, July 25, 2026, beginning at 11:00 a.m. at the Ellington Community Center, W3802 State Road 76, Hortonville, Wisconsin 54944.

Jeff's legacy lives on in the things he built, the traditions he cherished, and the many lives he touched through his kindness, friendship, and unwavering willingness to help others.
