Dennis "Mac" Earl McDonald passed away peacefully on August 7, 2025, at age 86. He was born on May 17, 1939, to Emma (Farrar) and James McDonald in Breed, Wisconsin. He was raised to have a hard work ethic that led him to Two Rivers where he worked at Mirro for 22 years, until he started his own business, Mac's Cleaning Service. After running his own business for 45 years, he decided to take a step back and started working at Jagemann Plating Co. for 12 years, finally retiring when he was 80. In his spare time, he enjoyed playing golf and darts; showing his Corvette at local car shows; watching the Packers, Bucks, and Nascar; kayaking and experiencing the outdoors; and of course working on many, various home improvement projects.

Mac is survived by his children Debi McDonald, Darci LaChappelle, and Derrick McDonald; daughter-in-law Laura McDonald; grandchildren James McDonald, Raymond McDonald, Kristen (Gage) Dawiedczyk, Nathan (Jeni) Jergenson, Megan (Travis) Jergenson, Miranda Jergenson, Hailey (Dylan) Hood, Ryan (Eme) LaChappelle, and Nick (Emile) LaChappelle; 17 great-grandchildren Jameson, Braelyn, Mark, McKenzie, Braxton, Abel, Dawson, Noel, Walker, Charleigh, Aiden, Bentley, Damien, Logan, Ella, Aleigha, and Autumn; sister Donna McDonald; and special friend Gloria Soto.

Mac was preceded in death by his parents James and Emma McDonald; son Dennis McDonald Jr.; son-in-law Paul LaChappelle; siblings Joyce (Al) Simonetti, Doug (Donna) McDonald, and Dean (Marilu) McDonald; as well as nieces and nephews.
