Obituary for Sharon Ruth Clark (Thill)

Sharon R. (Thill) Clark, age 79, passed away on January 30, 2024, surrounded by her family, at Aurora Medical Center, in Oshkosh. She was born to parents, Carroll “Buster” and Catherine (Gonyo) Thill on June 11, 1944, in Oshkosh, Wisconsin.

After high school, Sharon met the love of her life, James “Jim” Clark. They married on September 16, 1961, at St. John’s Church in Oshkosh. The two shared many passions including bowling, family trips with their children, occasional trips to a casino or two, and spending winters in Bullhead City, Arizona. Very often these activities were shared with their very special friends, Gary and Sherri Wuest. The four of them spent many years traveling the country and bowling in a couples league for more than 25 years. Sharon also made many close friends during her more than 31 years working at Winnebago Mental Health Institute, where she retired as a Food Service Supervisor. 

Sharon always loved spending time with her family. She particularly enjoyed watching her children, grandchildren, and great-grandchildren participate in sporting events and various school activities. E.J. Schneider Field became a special place for watching countless innings of baseball over 35 years. 

Sharon had a passion for crafts. She spent countless hours crocheting, knitting, sewing, and creating gifts for others. Her favorite creations were those that she made for her many grandchildren and great-grandchildren. She always made sure that everyone had a stocking with their name on it to hang for Christmas and hand-created snowflakes and angels to place on the Christmas tree. These special gifts have become heirlooms that will be passed down for many generations and are reminders of her desire to always put others first. Sharon will be remembered for being generous, loving, and kind-hearted.

She is survived by her husband, James Clark; children, John (Pam) Clark, Eric (Kristi) Clark, Dana (Randy) Losse; son-in-law, Gary Powers; grandchildren, Bryan (Samantha) Clark, Jackson (Alicia R) Clark, Shaina (Lukas P) Holtz, Mykala (Nate) Schwarz, Aadyn (Diana P) Holtz, Michael (Emily) Brueske, Christina (Troy) Powers, Patrick (Kirsten) Brueske, Jesse Powers, Andrew (Kerry) Clark, William Clark, Evan Clark, Erica Roberts, Emily (Ben M) Roberts, Stephanie (Matt A) Losse, Jesse (Clara) Losse; great-grandchildren, Gabriel, Eleanor, George, Philip Clark, Oliver Schwarz, Jackson Brueske, Meilani Rigo, Ivanka, Eve, Ivan, Victor, Ulrik Brueske, Hazel, Ruby Clark, Xander Tomko, and Finnley Losse.

She is further survived by her siblings, Michael (Mary) Thill, Patricia Bonneau, Joyce Saunders, Steven (Lorrie) Thill, Richard (Christy B) Thill; brothers/sisters-in-law, Sharon Clark, Bruce (Glenann) Clark, Thomas (David H), Charles (Dawn) Clark; and many nieces, nephews, and good friends.

She is preceded in death by her parents; daughter, Catherine Powers; brother-in-law Richard Clark and sister-in-law Carol (Mickey) Bloom.

Per her wishes, a private family service will be held. In lieu of other expressions of sympathy, the family asks that donations go to Scleroderma Research in Sharon’s name at  

The family would like to extend a very special thank you to the doctors and staff at the Aurora Hospital, Oshkosh, for their care and comfort during her transition.
