Michael D. Wahl, age 69 of rural Monticello, WI passed away Monday, September 6, 2021 at his home surrounded by his family. He was born June 17, 1952 at Great Lakes Naval Hospital in Chicago, IL the son of Myron and Donna Jean (Johnson) Wahl. Mike grew up in the Monticello area where he graduated from Monticello High School in 1970. On September 2, 1972, Mike married the love of his life, Diane Boisen at St. Victor’s Catholic Church in Monroe, WI. In 1975, he started Concrete Systems, then in 2000, Mike and Diane started Architectural Precast Company. As dedicated as Mike was to the business he spent his life building, his love for his family always came first. Mike was proud of his family. 

Mike is survived by his wife Diane at home; his children: Nicole (Jason) Jagodzinski of Fox Lake, IL, Jessica (Casey) Wood of Hermitage, TN, Bronson (Jesse) Wahl of Monticello, Kimberly Ann Hanson of Minneapolis, MN, and Megan Kessler of Plover, WI; 9 grandchildren; three brothers: Marcus (Jane) Wahl of Monticello, Thomas (Janice) Wahl of Monticello, and Gerald (Janet) Wahl of Monroe; three sisters: Melody Flesher of Monticello, Robin Feller of New Glarus and Patricia (Tim) Nicholson of Pembroke Pines, FL.

He was preceded in death by his parents; two brothers: Robert Wahl in 1974 and David Wahl in 1984; and one sister: Debra Wahl in 1957.

Mike was a member of St. Clare of Assisi Parish in Monroe, WI. When Mike wasn’t hard at work, he cherished the time he spent with his family and friends – especially his grandchildren and the memories they made together. Mike enjoyed sunny afternoons mowing the lawn, watching the Green Bay Packers, and every moment spent relaxing on the deck next to his wife of 49 happy years, Diane. Mike was always the guy who could have a conversation about anything, and had a humorous joke for every occasion. He was never afraid to speak his mind. He will be sadly missed and fondly remembered by his family and friends.

A memorial mass will be held Friday, September 10, 2021 at 11:00 A.M. at St. Clare of Assisi’s Parish at St. Victor Catholic Church (1760 16th St., Monroe) with Fr. Tafadzwa Kushamba officiating.

Mike thanks the team of nurses that he’s had over the years. He appreciated their dedication, company, and tolerance for his sense of humor. What could have been dreaded visits for treatments, were instead, treasured moments because of these new, unexpected relationships.
