Mary Jo Treml

November 24, 1962
February 5, 2022

It is with a heavy heart that we share the passing of Mary Jo “Jo Jo” Treml, a loving wife, mom, sister and friend, on February 5, 2022. Mary Jo passed away with peace and dignity in the loving arms of her husband, Dave, with her sons, Josh and Zach, by her side.   

 Mary Jo was born on November 24, 1962, to the late Leo and Marian (Salentine) Salmon. She was the youngest of seven children and was always the favorite of all her siblings. She grew up in the Village of Luxemburg and was affectionally known to everyone as “Jo Jo”. Growing up in a small town, Mary Jo made lifelong friends that are still very close today. She attended St. Mary’s Catholic School and graduated from Luxemburg-Casco High School. After high school, she received her accounting degree from NWTC. 

 Mary Jo married David Treml, her best friend, on October 3, 1986, at St. Mary’s Catholic Church in Luxemburg. They recently celebrated their 35th wedding anniversary and were blessed with two amazing sons, Josh and Zach. Jo Jo and Dave were truly an incredible couple. They were always ready for a great time and would happily open their doors for guests. They lived in the same home for over 35 years and, as a result, were able to raise their boys with a very tight knit group of neighbors who became great friends and often felt like family. 

 Mary Jo had a long and rewarding career of almost 40 years at Wisconsin Public Service. During her time at Wisconsin Public Service, she worked with many associates that became dear friends, especially her “Fab Five”. Outside of work, the “Fab Five” spent time together volunteering, traveling and vacationing at the Awassa Lodge. Mary Jo always enjoyed those outings, which were filled with laughter and brought so much joy to others. 

 Mary Jo had always looked forward to celebrating the “milestones” of life, like watching her boys grow up, get married, and start families of their own. She was especially looking forward to watching her son, Zach, and his fiancé, Vanessa, get married this fall and start their new life together. 

 Mary Jo is survived by her husband, Dave, and their sons, Josh and Zach (Vanessa Wentworth); Siblings: Judy (Carl) Mathu; Gary (Nancy) Salmon; Sue (Mark) Porath, all of Green Bay; Glenn (Lori) Salmon, Luxemburg, Debbie (Russ) Schuettpelz, Sobieski; Karen (Joe) Linskens, De Pere; Brothers and Sister’s in-law: Mary (Ed) Kimmeth; Diane Treml; Dan (Sharon) Treml, De Pere; Ken (Barb) Treml; Tom (Pat) Treml and Mike (Judy) Treml, all of Green Bay; many nieces, nephews and cousins.

 Mary Jo was preceded in death by In-laws, Felix and Laverne Treml, and the family pup, Lexi.

 Mary Jo fought a 19-month battle with pancreatic cancer. She never gave up on new treatments, surgeries, tests or procedures. She faced each day with courage, optimism and dignity with her guardian angel, Dave, at her side. There was not an answer for her here on earth and God wanted her at peace with him in heaven. We are so grateful for our time with her and will cherish our many memories. We want to thank all the doctors and staff at the Mayo Clinic in Rochester, MN, the Vince Lombardi Cancer Center at Aurora Hospital, and especially Dr. Gautam and Dr. Bosco.  We also thank the caring staff of Aurora Hospice at Home Care, and the compassion and friendship of Deacon Jeff Prickette.
