Meet Dr. Alex Fetner

Dr. Alex Fetner graduated from dental school in 2011 at the University of Florida. He practiced as a general dentist in Chicago and Jacksonville prior to returning to the University of Florida for his periodontal residency in 2014. He came home to Jacksonville in 2017 to join Fetner & Hartigan and received his board certification in periodontics in 2019.

Dr. Alex has lectured on multiple topics, including the link between periodontal disease and cardiovascular disease, as well as bone grafting for dental implant treatment. His master’s thesis was based on research about a type of periodontal disease that affects adolescents, particularly those of African descent. He prides himself on compassionate and conservative care for his patients with evidence-based treatment. He also likes to give back: Dr. Alex was on the board of the Jacksonville Dental Society for four years. He organized the “Give Kids a Smile” event, where dentists provide free care to children in need. He also served as the President of the Jacksonville Dental Society from 2023-2024.

Dentistry runs in the family, and Dr. Alex is continuing the tradition: he is married to Dr. Jackie Fetner, a Pediatric Dentist in Jacksonville. They now have four children: Emily, Max, William, and Jack. He enjoys food, reading, woodworking, running with his dog, and playing tennis— especially against his brother and fellow periodontist, Michael. He also loves being a periodontist!
