After high school Bonnie attended DMLC and graduated in 1967. She taught elementary school at Good Shepherd in Phoenix, AZ and at St. Peter in Milwaukee. She married Robert Koepke, also a DMLC graduate in 1968. In 1972, Bob accepted a called to teach at Grace in Oshkosh, WI. He taught there for 35 years before he retired in 2007. For almost 35 years, Bonnie struggled with medical and emotional problems. Bob was her faithful loving husband and caregiver. The Lord blessed their marriage with the gift of 2 children, James and Jennifer. She and Bob were blessed with 6 grandchildren. 

Bob’s health is also poor. He was hospitalized at the time Bonnie died. She fell at home while alone, broke her ankle and was in a nursing home for rehab when she died peacefully in her sleep, June 20, 2008.At her funeral June 25, which I attended, Pastor Schoeneck said

Bonnie was one of a handful “female Jobs” he has known in his ministry. In spite of her medical and emotional ups and downs, her spiritual health was good. 

My memory of Bonnie in high school is a happy, positive, intelligent, and fun friend. She had a beautiful singing voice. When she walked, she was so fast that she seemed to scamper away like a bunny. That is how she got the nickname, “The Hopper.”
