Michael “Mike” Bernard Datza passed away at the age of 57, peacefully surrounded by his daughters after a courageous battle with mesothelioma on May 7th, 2022.

Michael was born April 25th, 1965 in Milwaukee, WI. He was an accomplished track and field athlete who went on to work for school districts as the Buildings and Grounds Director. He had a way of fixing the unfixable and a knack for teaching his trades. He was respected by all employees and truly cared for them. Outside of work he loved nature, hunting for antiques, and his land in Mauston. He had a fondness for the champagne of beers, Miller High Life, and traditional Polish cuisine. He had been known to cut up the dance floor, and make just about any situation funny with his sarcastic humor.

Mike retired in August 2021 with dreams of enjoying his land up north and traveling to places he’d never been.

Michael is preceded in death by his parents Walter and Geraldine Datza, and nephew Patrick McLaughlin. Michael is survived by his beloved daughters Sarah(Michael Semrow) and Megan, his four older sisters, Kathy(Pat) McLaughlin, Christine(Fred) Kirch, Connie(George) McNair, Mary(Chuck) Moore and countless nieces, nephews, and lifelong friends. He also leaves behind his cherished canine companions, Sadie, Lulu, and Casey.

A celebration of life will be held at Heritage Funeral Homes in New Berlin on May 19th, 2022 from 4-7pm. In lieu of flowers, donations to Elmbrook Humane society are appreciated.

    Mike was a great friend as we hung out with his 1970 Caddy and great to work for him as a contractor at Greenfield schools. He will be very missed.
    I hope we will consider Mikes passing as we all need to choose to live this life with eternity in mind, living to trust and obey Jesus Christ, our only hope.
    My prayers are with the family.

    I worked 7 years for Mike when he was the building & grounds supervisor at Elkhorn Area School District. We had good working relationship and always had good conversations. He will be missed.

    I met Mike in 1976. We were in CCD class together at Holy Apostles. My Mother was the teacher and I quickly got us both kicked out. A little foreshadowing, I think. Buddies through middle and high school. It was nothing to ride bikes the six miles between our driveways …With cars, the world was our sand crab. Always the attention getter, Mike was the 7th or 8th funniest men I knew. He touched many people, (some with permission). Far too many stories I don’t dare share here.
    Like a flash, 40 years later and blessed with our own beautiful families.
    . Here we are. And you are gone.
    Mike, I love you like a brother. Always will
    Selfishly, my heart is broken.
    To you, God speed.
    Till we meet again.

    May the God of all comfort comfort you during this time of loss.
    I appreciate how Mike supported a part time custodian to attend tracings off site and within the district. He supported me during my adjustment to the new routines and was patient with my rants.
    Thanks Mike.

    Megan, I am so sorry for your great loss of your father…cancer is a terrible disease that takes way too many young people…I know that fact because both my late husband and my son passed away due to cancer at 41 and 38…Although I never met your dad at conferences, I know he must have been a wonderful man since he had such a wonderful daughter, you!!
    Love and hugs
