Tonna and Mack raised their four daughters in her hometown. She never missed morning coffee with her dear friends Connie Flakus and Kathy Weiler and many other ladies that joined them at the kitchen table. She worked as the city secretary and managed Cox Drywall. Tonna was a member of the Colome School Board, enjoyed working for US Census and was a longtime election volunteer.
Her grandchildren were her greatest treasures. For many years, all the kids enjoyed summer vacations in the Black Hills with Nana and Papa. A love of travel took her all over the world. Over the years, she enjoyed spending time at Katonka Cabin in Hill City and vacations to Rome and Paris with her very special sister-in-law Julie. Tonna and Mack also made time for shorter trips to auctions and other cultural activities.
Tonna’s ability to make others laugh was her most admired trait. She taught her daughters and close friends how to see the humor in any situation.
