Cullumber Inc. is a book distributor that had been operating in its original facility since 1990. The increase in certification programs and continuing education requirements in several professions has contributed to an annual growth rate of 15% for Cullumber since 2015. Cullumber' original facility became obsolete by early 2020 because of the increased sales volume and the fact that Cullumber now carries CDs in addition to books. On June 1, 2020, Cullumber contracted with Black Construction to have a new building constructed for $ 5,200,000on land owned by Cullumber.
