On October 31, 2003, Roberta retired after 34 years.

Roberta was a faithful member of Presbyterian Faith. She was baptized and confirmed at the First Presbyterian Church in Holdrege, and was the church organist from 1959 to 1966. She was then a devoted member of the Axtell Presbyterian Church, where she served as Elder and Deacon, a Circle Leader, Presbyterian Women officer, and the church organist from 1967 to 2009.
