Astoria, NY |
The most disrespectful, unhelpful staff I've ever experienced. Rude on the phone when I could actually get someone to return my calls. 5 weeks post procedure and I still didn't get the doctor or staff to contact my insurance company to get. Lear ace on a prescription. I have yet to get a call from the doctor himself. Don't go to this doctor.
