The evening of my filling I received a call personally from Dr. Yu just to check that everything was ok.  Now THAT is customer service!  Everyone at Dr. Yu's office is fantastic.  I've had several dentists in the past and Dr. Yu is the best by far.  Dentistry really is an art... you can settle for some 'other guy' because he's close to your office or really cheap but you're only doing yourself a disservice.  Stop wasting time reading reviews and just book your appointment with Dr. Yu; you'll be glad you did.
