“This is a very efficient and professional dental office.  The answer the phone, are on time with appointments, and seem happy in their jobs.  Justin cleaned my teeth very thoroughly and clearly explained better preventive care.  Dr. Seo carefully examined my teeth and reviewed my xray, taking care to detail areas that need more attention.  I love my new dental office!”
