I visited this practice few times and i liked the service that they provide and you can walk-in. However, for my last visit i was never informed that the 30 second nitrogen spray procedure was not going to be covered by my insurance. I don't ever get bills from insurance but after paying my $30 co-pay, i am seeing another big bill for 30 second procedure that never fixed my issue. If i had known that i would have to pay for this procedure then i wouldn't have done it which doesn't fix anything. I hate writing review but this wasn't acceptable.

My son, husband and me all have uniquely different and persistent dermatological issues that NO other Dr. has been able to address until we found Dr. Militello. He is simply awesome.

Dr. Giuseppe Militello, MD is one of the best dermatologist I ever seen. His empathy and concern towards his patients is excellent. He even answered a phone call himself when the office was closed.
