I would highly recomend this dentist, Dr. Yi is very good with a needle and is friendly and it seems that he really cares about his patients.I have had cleanings , a filling and I am on my second crown right now. The prices are very reasonable and the office is clean and hi-tech like you would expect in fairfax. va. The waiting room is nice with free snacks and drinks ect. the staff is friendly and knowledgable it seem as they all enjoy there job. The take Met Life dental as well as I am sure many other dental plans. They are honest also , I was in for a build up for a crown and they discoverd that some of the work had be doen years ago and I had no idea, this reduced my bill by $.110
