Beth Thompson
Asst. Director of Finance
bthompson@ddmga.org

Beth joined the Business Office staff in May of 2015 after serving for a number of years as the Finance Manager at First Baptist Decatur. Beth is nearly a native of Lilburn, where she and her husband Van currently live with their two boys. Beth graduated from GACS and then GA State University with a degree in English Lit, but her jobs throughout college gave her experience in accounting. In fact, she and Van met while she was working as a staff accountant in a firm located in the building right next to DDM’s Central Office. However, she initially studied Theatre Arts in college and has been able to put those skills to use by volunteering as the drama director at her boys’ school, Parkview Christian School in Lilburn. Every spring, she is knee deep in Shakespeare, so don’t be surprised if she lets a bit of the King James English slip from time to time. She and Van love to stay active – he is an avid runner, but she is a self-proclaimed loper. Their family attends Grace Fellowship in Snellville.
