Dr. Ingber's and Provazhnik's as a doctor is fine but the customer service and accounting procedures are a huge waste of time. Even for procedures that were covered by my insurance, they charged me first when they should have collected the amount from my insurance company (Delta Dental) directly. In another instance, they charged me much more for wisdom tooth extraction than what Delta pays them and never told me that they owe me $200. After I raised the issue, they said that they'll send a refund check but then went ahead and used $160 for regular cleaning and told me that I should expect a check directly from the insurance company. The procedure was done on March 14th and I still have not received the check from Delta in spite of calling Dr. Ingber and Provazhnik's office 3-4 times in the last 3 months.
