Keith George Kienitz

A devoted husband, father, grandfather, great-grandfather, and friend, Keith lived a life marked by service, unwavering work ethic, and quiet generosity. A proud graduate of Michigan Technological University with a degree in Civil Engineering, he turned his expertise into a lifelong commitment to building-both homes and relationships.
As a contractor, he built at least eleven homes, each a testament to his skill and dedication. But more than his work, it was his willingness to lend a helping hand that made him "the guy to call." Whether pouring concrete for neighbors' driveways or donating over 40 gallons of blood, his legacy is one of tireless giving.
He was a proud member of the Knights of Columbus and found joy in fishing, hunting, and working in his garden. His connection to nature reflected the grounded and genuine spirit with which he approached life.
Keith leaves behind so many loved ones. He is survived by his beloved wife Nancy, and two children Julie and Mike along with their spouses (Mike, Tracy). Keith was the proud grandfather of four: Ryan, Lyndsay (spouse Saeed), Carly and Payton and great grandfather to Lyndsay's two children, Giselle and Clayton, all of whom brought him great joy. Keith is also survived by a brother Lyle (Alice), and two sisters Velva Dell and Leola. Nancy also has brothers Joe (Carol), Don (Jackie), Bob, Dave (Nancy), and her sister Kathy (John) and many nieces and nephews.
