His office has very friendly staff. Dr. Joo will take his time to answer all questions. Unlike many dental office in the Northern VA, his office is not structured like a factory. They do not try to rush you in and out. The level of dentistry is high quality. Dr. Joo's price is about average but the service is a top notch. He did Invisalign for my wife and me. We are very happy with the result and the service.
