She was born July 20, 1922, in New London, WI, to Justin Peter and Blanche Lydia (Rand) Tonk. Berdella grew up in Milan, OH, and graduated valedictorian from Milan High School in 1940. Berdella graduated from Olivet Nazarene College in 1949 with a B.A. in business education and went on to earn a M.A. in education from The Ohio State University in 1952. She taught business education in Milan and Fremont, OH, for several years. While at The Ohio State University, she met her husband, Bruce Wendell Wilkinson, and they were married Oct. 17, 1953. Berdella was a committed Christian, and very active in the Church of the Nazarene and in raising her family. She was an avid reader, crafter, baker and secretary. As her children grew older, she worked as a departmental secretary at Michigan State University, where she studied for and passed the Certified Professional Secretary exam, the first to achieve this at Michigan State University. In later years, she worked in the registrar's office at Spring Arbor College until retirement.
