Dr. Han thoroughly explained my situation. He then told me my options and the probability of his plan working. He even complimented my teeth. Dr. Han is kind, professional and has excellent bedside manners.

There was very little explanation of what was going to be done, just braces. He did not discuss any other options.

Dr. Han always does a great job of explaining everything and his assistant this time, kaylie, was very nice and explained everything perfectly.

I would recommend that the Dentist perhaps tell the patient what theyre going to be doing in your mouth prior to having you lay back--especially for orthodontic work, this lack of communication can be upsetting
