Meet The Doctors

Derek A. Lewis, D.D.S.

President; General, Cosmetic, Orthodontics & Implant Dentist

Introduction: As a young man, Derek Lewis always enjoyed working with his hands,"tinkering" with gadgets, and seeing the fruits of his labor materialize before his eyes. With a little persuasion from his mom, he investigated various professions within the field of health care to find a career that would allow him to do the things that he enjoyed as well as help others. As a result, a dentist was born.

Dr. Lewis has the professional experience that only comes with being in private practice for over 25 years. In addition, he has gained invaluable experience while working simultaneously as a dentist for various hospitals and health care organizations. He began his private practice as a general dentistry provider and, over time, has honed his skills to include cosmetic, periodontic, orthodontic and implant dentistry to the repertoire of services that Dr. Derek A. Lewis, D.D.S., P.C., and Associates offers to its patients. Dr. Lewis is constantly working to improve and expand his skills in an effort to provide the best care, latest techniques, and advanced technology for his patients.
