Betty was born on August 5, 1936, in Harrison, SD to Leendert and Jennie Vanden Berge. She was baptized in the First Reformed Church of Harrison and attended school in Douglas County.

In 1968, they moved to Burke, SD where Betty ran an in-home daycare and was a 4-H leader for several years. She was a member of the United Methodist Church in Burke.
