I highly recommend Long Island Spine Specialist (LISS) to anyone looking for a honest opinion and treatment for Spine/back issues.

Dr. Mermelstein is thorough in looking at all aspects of my injury, explains everything clearly, and answers all of my questions in a way that respects my life style and level of activity. The office staff is fantastic from the people at the reception desk who are friendly and helpful, to the X-ray technicians who are so personable and also sensitive to my injury and how to get the images they need while at the same time making sure I am as physically comfortable as possible. I have already recommended Dr Mermelstein and his office to a friend who was looking for a spine doctor.
