I went to Dr. Yi and wasn't too impressed, though I do believe he is a good dentist. He wasn't too friendly and didn't put me at ease, especially since I needed a lot of work. I ended up only having my cavities filled with him, which turned out fine. He did take x-rays and photographs of my mouth to initiate the treatment process. The way he described things suggested he was knowledgeable and perfectly capable. However, because of the extent of the dental work I needed (tooth extraction, implants, straightening), I decided to seek a different dentist. The staff was pleasant enough. He is perfectly fine and not too expensive, but if you want a dentist who is more pleasant and personable who will make you feel at ease, I would go elsewhere.
