Dr. Mike Maddox

was born and raised in Gadsden, AL. After finishing college at the University of Alabama in Tuscaloosa, he moved to Birmingham, AL to pursue his dental education at the UAB School of Dentistry. He graduated from the UAB School of Dentistry in 1982 and then moved back home to Gadsden to open his dental practice on South 3rd Street. In the early days, Dr. Maddox and his wife Cindy lived on one side of the office duplex while Dr. Maddox practiced dentistry on the other side. The practice as well as their family soon outgrew that arrangement, but nonetheless, the office on South 3rd Street has always been home! Dr. and Mrs. Maddox raised four daughters in Gadsden including Dr. Mary Lynn Shadix and Dr. Caroline Spruiell.

Dr. Mary Lynn Maddox Shadix

also attended the University of Alabama in Tuscaloosa for her undergraduate degree in Biology and then the UAB School of Dentistry, where she graduated with her DMD in 2017. She and her husband David moved back to Gadsden shortly after to start their family. She is excited to serve the community she grew up in and to continue building the practice her father started.
