I haven't seen Dr Yung since my first procedure two years ago instead been handed off to his flunkies, always a new one. Several crowns since have needed redoing and the appointment procedure is horribly disorganized. They are generally very good with insurance until my group's insurer (Guardian) decided to drop our group a month earlier than our coverage indicated. Instead of sending any kind of invoice, I got a call telling me I had to pay over $800 immediately. Office is cramped and dark.
