After retiring from Athens City Schools as educators, Faye Tribble and Deborah Johnston joined forces to launch a mobile drug testing service in 2016. The business soon opened an office at 121 Cloverfleaf Dr in Athens, AL, to serve those individuals that needed drug and alcohol screening for a variety of reasons. We offer a variety of options to employers, courts, lawyers, DOT workers, and schools for successful delivery of a drug free policy or contract. North Alabama Drug Testing, LLC (NADT) is available 24/7, 365 days for testing services. Appointments are necessary for office collections. NADT is a Women's Business Enterprise National Council and Women Owned Small Business certified company.
