I have known Dr. Phan for around a year and a half and think she is a wonderful and competent dentist. I have gone to her for general checkups, cleanings and to have dental fillings, with great results.
I do however do not completely agree with the offices billing practices. I do not have insurance, and found that the fees were expensive. After my initial checkup, I had an x-ray which showed a cavity. The office quoted me a price to have it done, and even though these x-rays showed the depth of my cavity, they said it was "deeper than they first though", and charged me $55.00 more than the quoted price.
Also, this is just my opinion but I would think that if a person did not use Novocain in a procedure, they should not have to pay for it. For me, the filling cost the same weather I use it or not.
But the billing issue aside, Dr Phan is still a excellent Dentist, and she does very high quality work, so this should not prevent anyone from going there. I am sure that if you have insurance you will not run into the same issues I have had.
