Michael J. “Mike” Arthofer

Michael J. “Mike” Arthofer, age 81, of Peosta, IA, completed his earthly journey on Thanksgiving Day, Nov. 25, 2021, at home while surrounded by his loving family. To honor Mike’s life, a graveside service will be held on Wednesday, Dec. 1, 2021, at 10:30 a.m., at the St. Catherine’s Cemetery with Rev. Dianne Grace officiating.  Full military honors will be accorded by the Dubuque Marine Corps League.  The Tri-State Cremation Center is humbly serving Mike’s family.


Mike was born on October 20, 1940, in Dubuque, IA, 1 of 7 children to Peter and Charlotte (Finzel) Arthofer.  Mike always knew that his personal drive and determination would lead him to find success in every venture and dream that he chased.  He began by honorably serving his country with the U.S. Navy.  Mike was united in marriage to his beautiful bride, Mary “Mazie” Steffen, on October 27, 1962, and the two of them have spent their lives together united in one common front; nurturing a loving family.  Mike provided for his family by investing over 37 years with the Interstate Power Company before retiring.  His years there brought him great pride as he had started at an entry-level position and climbed to the top before completing his mission there.  He spent 17 years on the Interstate Power Credit Union Board of Directors and was a Quarter Century Club inductee.  Mike and Mazie enjoyed traveling after his retirement. When home, he enjoyed operating his own business, Arthofer Lawn Repair, and found the time to spend 20 years working with his friends at the H&J Auction Company.  Mike was a good and decent man who always put his family and friends first.  He took the things that truly mattered in this life seriously and always knew how to keep his heart at home.  We will miss Mike’s joyful spirit, bountiful laugh, and passion for all that was good.  Thank you, Mike, for leaving behind such a positive legacy for your generations left behind to follow and we pray that your reunion with your family, especially Michelle, brings you more joy than you could have imagined after your last 15 years battling Parkinson’s.  May God bless you and keep you safely in His loving arms.

    So sorry to hear Mike has passed. He was one hell of a cousin. Mazie and family, my heart ache for you. You made the Arthofer name proud. Auctions will not be the same without him. Cousin Debbie

    Mazie and family so sorry for your loss. Mike was a wonderful man and will be missed. I am sure Dad (Gary Cremer) will meet him in heaven and they will have a great time. Again so very sorry for your loss.

    To the Arthofer family; I knew Mike many years ago from his time at Interstate Power Co Powerplant upstairs office. My brother Joe(deceased 1985)and I often times engaged with Mike when he needed us to come over to the power plant, or when he came to our facility just a block away at 400 E. 7th St. for any steel need. I vividly remember Mike’s perpetual smile and his ready laughter. Despite these many years since then, I hold his memory fondly in my heart. I’m sorry for your loss but as you are – I’m sure Mike no longer has the shakes from Parkinson’s. I will keep Mike in my daily prayer petitions and thank him for allowing me to have shared in his life.
    With my condolences, Kevin Kisting of the Voggenthaler Co.
