    I would not recommend based on my office experience. I was referred to Long Island Endodontics by…read moremy dentist, with whom I have been a patient for years. Long Island Endodontics charges $275 for a consultation without x-rays. If you choose to have the procedure performed at that office, the consultation fee is applied towards your bill. I did not receive a receipt for the $275. It was a mistake on my part not to ask for one. The invoice for this visit was sent to my place of employment, which I find to be very unprofessional. I was billed $627.00 for x-rays. Patients should be informed that their x-rays are on the high end. My dental insurance only covered $87.00 and I can understand why. The individual responsible for billing is unprofessional in communication, both verbally and through email. My visit to this office is costing $550 with no dental work being performed. The kicker! They have pursued legal action against me for the $275. I did inform my dentist about my unfortunate experience with this office. I was provided me a new referral and had a much better experience. The total cost for my root canal (two visits), crown and x-rays, was less than $250.00.

Dr. Berry was so gentle that I actually fell asleep during the procedure I was so exhausted. If you're ever in I need of an endodontist definitely contact Dr. Gordon Berry... an excellent Doctor and a very kind human being.
