The Dentist, Dr. Singh is a very skilled dentist and her assistance Sindy is also. However, I am considering changing my dentist office due to the fact that eventhough, I am an in network patient, the Billing Department leaves much to be desired. Most of my procedures were pre-authorized by Metlife. So therefore the Billing Department should know exactly what to charge me, however, one time I was owed monies and the next I owe the dentist office. And with pre-paying for any treatment. I feel the Billing Department should know. exactly what to charge.
