1 /5 Client: I recently had a first visit in the practice of this dentist (SJ Oh, DDS). After my cleaning, I had to wait for about 30 minutes to see him. He finally showed up with an attitude of arrogance barely acknowledging me, let alone the long wait I had. Then, he literally left the room within a minute or two without any basic professional courtesy. How rude and unprofessional was he. One would expect better, much better, from a dentist in a small family-oriented practice in a small and welcoming city like Charleston. Giving him one star is even a favor he doesnt deserve.
