Dr. Kim is a very friendly and caring professional and extremely skilled dentist. I’ve had 2 fillings done by him and I had a great experience both times. At no point did I feel that he was trying to talk me into doing something that I didn’t need. He carefully explains his recommendations and was very transparent with the cost. I would recommend his office without any hesitation.
