  • "Very accommodating staff. The concierge are very friendly. Dr Diaz and her assistant work gently. Dr Diaz had very light hand I didn't even feel any pain. She spoke very specific about the insurance coverage what is covered and not. She explained very thoroughly about the procedure and condition of your teeth and gums. I absolutely recommend her clinic to my friends and family. Thank you Dr Diaz and your staff for making my smile bright again."
