Michael Lawrence Theisen, age 62, of Pearce, Arizona, passed away peacefully, surrounded by family, at Peppi’s Place/Tucson Medical Center Hospice on January 6, 2024, after a courageous five-year battle with metastatic leiomyosarcoma cancer.

Michael was born on August 27, 1961, in Friendship, Wisconsin to Romie and Shirley Theisen. He grew up in Springville Township, Adams County, Wisconsin and graduated from Adams-Friendship High School in 1979. Michael was a standout in AFHS athletics, especially football and basketball. He lettered in four sports. He went on to play football at Rochester Community College and then Arizona State University, where he was on the ASU team that won the Fiesta Bowl in 1983. Michael loved living in Arizona and remained there for the rest of his life. He ran a floor covering installation business in the Phoenix area for decades. He was also passionate about rebuilding old trucks and raising exotic birds, including macaws and toucans. Michael loved all animals immensely and was a gentle giant around cats, dogs, birds and even wildlife.
