Dr. Greissinger is an excellent dentist, however, I would say that Nina working at the front desk leaves much to be desired. In an attempt to do my due dilligence in selecting a Dentist, I specifically asked if this office accepted CIGNA. I was told there would be no problem. When I got a bill for a charge denied by CIGNA because it was already condidered to be paid for under another procedure, Nina - with such a "friendly disposition" - stated that since they were out of network, I would still owe the differnece and that it is "up to me to know my own benefits". Now THAT'S what I call service. Sorry Michelle, love ya lots, but with Nina's poor attitude and threatening to send me to collections if I don't pay the difference, I can't say I'll be back. Patients BEWARE!
