George Kostakis, DDS

I am motivated because of painful childhood experiences with a dentist who did not use novocain for fillings. Memories of that pain have driven me to provide comfortable care for my patients. I graduated from the University of North Carolina School of Dentistry in 1986. I began dentistry in Florida in 1987 and have been at my present location since 1993. I am happily married with three children, all boys. I get my thrill from making people’s smiles beautiful. I am committed to new advancements in dentistry that make my patients happier including cosmetic dentistry, digital photography and digital x-rays. My hobbies include accordion music, fishing, tennis, golf and traveling with my family.
