Mary was born on July 16, 1942, to Lester E. Schepker and Marjorie Sullivan Schepker in Davenport, Iowa. Mary’s life was one marked by dedication, compassion, and a zest for life. In Davenport, Mary attended Sacred Heart Cathedral School, Immaculate Conception Academy, and graduated from Assumption High School in 1960.

Mary had a distinguished career that included work in New York City, Armour-Dial Inc. in Arizona, Nehlsen Communications in the Quad Cities, as well as several years in banking.

In 1991, Mary married William “Bill” Kellenberger in Long Grove, Iowa. After Bill’s passing, Mary formed many dear friendships at the Suites of Bettendorf. In her final months, she was blessed to be in the presence and care of her son Richard Wolfe Jr.

Mary was an avid sports enthusiast and found joy in playing and watching golf. She passionately followed Notre Dame, March Madness, Assumption High School athletics, and professional tennis. Her quick wit and humor enlivened countless evenings spent playing board and card games with family and friends. She was also proud to have appeared on the television shows Jeopardy! and Tic-Tac-Dough.

Mary served on several boards and commissions, including the Board of Directors for Vera French and the Quad City Marathon, the Scott County Regional Authority Board, and the Judicial Magistrate Appointment Commission from 2014 to 2020.
