First-class treatment. This was a routine cleaning except that it was after I had a cochlear implant. Irina, the hygenist, called the office of the surgeon who had done the implant to find out if precautions were necessary for the cleaning or x-rays (if needed). Given the go-ahead, she proceeded to do a very thorough cleaning. Dr Chang was his usual friendly self. I was very impressed by the professionalism and warmth of the care provided.
