“I just wrote another post but, I’ll repeat it in an abbreviated version. The whole staff at Newport Center Dental Group is excellent! For years my son and I have had such a wonderful experience getting dental care from Dr. Naidus and Dr. Lyon. We never dreaded going to the dentist because we knew we are in such capable hands. That included the support staff, too! Now, I’m going to be seeing Dr. Hipolito and, after meeting her only once, I already know that she is so professional and kind! I am looking forward to another great experience!”
