This man has got to be the best dentist in Seattle - Dr. Chang is a pleasant and courteous man, a highly competent and a very skilled professional who knows how to treat people - Dr. Chang did an extraction for me that had the potential to be very painful. Not only was it fast, it was also pain free. I have seen many dentists and I think Dr. nejamin Chnag may be one of the best yet. I highly recommend Dr. bejamin Chang.
