My 4-year-old son has been going to Dr. Kim for a while and recently had a few fillings done with Dr. Kim, and he did extremely well with her gentle bedside manner and a TV on the ceiling. He received some toys and a balloon after the treatment, and he can't wait to go back! He did not cry at all. So I assume that he was not in pain when he received treatment. The facility seems brand new and clean with high tech equipment and computers. The staff and the doctor were all very friendly and kind. I would recommend her to anyone out there!
