I am a temporary DC resident from California and Oregon, and I visited 2 other dentists in Washington, DC before trying Dr. Kwon. Being used to quality dental facilities and work in CA and OR, I was horrified with the antique equipment, lack of dental technicans, know-nothing receptionists, and "good enuff" dental work attitudes at the prior two dental ofices. Dr. Kwon's office, staff, and quality of work were worlds apart from that of the prior two DC area dentists I tried. Dr. Kwon's office has state-of-the-art equipment, proficient staff members, and takes time to do the job right and to the highest standards.
