Dr. Rosenberg is an excellent oral surgeon. But his office and billing practices are a nightmare. They charge you more than the in-network allowances for the procedures and then refuse to refund you the extra money, which is probably why they require you to pay when you receive treatment. They spent SIX months saying they had submitted info to the insurance company, and never did, and just blamed the company (Metlife; never had a problem before with their receiving bills from dentists.) Could not get the pre-treatment estimate right. And when they finally got a check from the insurance company, because they stated on the form that the DENTIST should receive the payment, they told me for two further months that they had not received it. Metlife traced the check; the office HAD received it, deposited it, and then they told me they had credited it to someone else's account! This, mind you, was for procedures (expensive) that I had already paid for, on the spot, which, as I pointed out in the first part of my review, they overcharged for me for and refused to refund my money, even though Metlife said that they were not allowed to do this. Very disappointing. I spent hours on this. Stay away!
