With heavy hearts, we announce the passing of Mary Jo Diers, 85, of Athens, who died on June 24, 2025, at Copperleaf Assisted Living in Marathon, surrounded by her loving family. She was born on June 4, 1940, in Iowa to the late Carl and Leona (Schneider) Johnson.

After graduating from St. John’s Catholic High School in Bancroft, Iowa, Mary Jo worked for Doc Eagan, Northwest Airlines and Dr. Miller Dermatology. On April 26, 1969, she was united in marriage to Ronald “Butch” Diers, and together they raised three children. Being a mom, homemaker, grandma and greatgrandma were roles she was most proud of and excelled at.

In 1980, Mary Jo and Ron began farming together and worked side by side on their Athens farm. They enjoyed attending Brewer games, traveling to visit family in Iowa and Missouri, playing cards, fishing, trips to the cabin, Friday night fish fries, couples bowling league, their annual bowling group and park party outings.

A member of St. Anthony’s Catholic Church, Mary Jo served on the PCCW Board, volunteered at the church food stand during the Athens Fair and helped with church fish fries during Lent. She also enjoyed her time as a reading buddy for St. Anthony’s School.

She is survived by her children: Patti Diers of Athens, Vicki (Mike) Tessmer of Oshkosh and Jim (Ann Marie) Diers of Athens; grandchildren: Lucas (Kara) Diers, Alyssa (Matt) Weise, Hannah (Steve) Dahl, Jared (Haley) Diers, Stella (Nash) Cole-Ellenbecker, Emma Tessmer and Ethan Tessmer; and great-grandchildren: Henry, Leona, Vera, Dawson, Theo, Felix and two more on the way. Mary Jo is also survived by her siblings: Betty Rowlet, Karla (Karl) Schaa, Helen Ricke, Jerry (Sue) Johnson and Mick Wolf; sisters-in-law: Elmira Masanz and Joan (Gary) Smidt; and dear family members Sandy (Curtiss) Erickson, along with many nieces, nephews, extended family and friends.
