Dr Mermelstein is an excellent doctor. I was very fortunate that my primary doctor referred me to him. He is very attentive and addresses all my questions and concerns.

My visit to Long Island Spine Specialists with Dr Mermelstein and staff couldn't have been more pleasant and extremely informative. Dr Mermelstein and his entire staff from the receptionists up front to administrative assistants, and his PA were absolutely wonderful and very personable. Dr Mermelstein was very thorough and informative in his review of my cervical condition and explained all the necessary steps in order to relieve and improve my condition. I fully recommend this organization to anyone who needs to resolve spinal issues. Less

Always a pleasure to meet with Dr Mermelstein! Hes such a nice guy. He takes his time with you , answers all your questions, and never makes u feel your being rushed. He impressed me by not rushing to do surgery right away, he advised me to try this brace shaped for just my body to see how much he could straighten me out 1st. As a last resort he recommended I have a fusion from T-3 to the Sacrum with 2 rods . He’s a great surgeon , I’m 66 and he fixed my scoliosis and kyphosis and everybody’s is pleased with my remarkable recovery! I can’t say enough positive things about this man , he is absolutely the best., I am very grateful for his patience , his knowledge ,his kindness and his compassion. Maria Nappi Less

Dr. Mermelstein was very thorough as he looked at my MRI. He noticed something no one else saw before during my 2 year neck issue problem. He was very professional, kind and didn’t rush me as a patient. Less

Dr. Mermelstein has been my orthopedist for 20 years. He is by far an example of what a medical professional should be: prompt, caring, thorough, willing to explain your situation, and answer any and all your questions. I have surgery scheduled with him in 2 months. I have complete confidence in his skills and would never consider putting myself in any other spine surgeon's hands. Less

Another fantastic informative visit. Dr. Mermelstein is the complete package - extremely competent, kind and patient! I have total confidence in his abilities as a surgeon. The office is so efficient. Less

Dr Mermelstein and his staff are so attentive and courteous. They speak to my children on their level and make everything relatable to what their are going through. The office staff is prompt calling me back and answering Any concerns I may have. Very professional. Less

Dr. Mermelstein has been taking care of me for over 25 years. He is the surgeon that other doctors trust with their family members and their own health. He is so intelligent but so down to earth in the way he treats his patients and staff. I trust him 100% and he has never steered me wrong or let me down. He treated my back and neck pain conservatively for over 20 years because that is what I wanted. When I was finally ready to have surgery, he took the best care of me. His staff is a reflection of him: Intelligent, compassionate, highly skilled and leaders in their field. Thank you Long Island Spine Specialists for taking the best care of me every single time for all these years! I know I can count on all if you to work hard to be as cutting edge as any practice in NYC. Less

Dr Mermelstein was referred by my chiropractor, three years ago I had back surgery because I had chronic back pain. The surgery didn’t seem to accomplish the goal which was to feel relief from the pain it just continued to get worse since the surgery. I saw Dr Reed first and then Dr Mermelstein came in and discussed his thoughts based upon my comments as to how I was feeling. They gave me the most thorough examination I’ve ever received it was remarkable, they listened to everything I had to say and were so understanding and so very kind even when some of my questions seemed silly. They were both so patient through the entire exam I didn’t feel rushed even for one second. They scheduled me for and mri as well as a ct scan as the records I have are two years old and probably don’t give an accurate depiction of what’s really going on in my back. I’ve only had one visit so far but I’m looking forward to following thru with the plan that’s been laid out for me. The doctors were super professional yet broke everything down to terms a regular person could understand. My visit was a pleasure and I feel confident that they’ll get to the bottom of what’s been ailing me. John O’B Less

Dr. Mermelstein literally saved my life; I was in severe pain and agony from a large herniated disc in my lower back that was crushing my sciatic nerve. My entire left leg had stabbing pain down to my ankle; my left foot was totally numb and tingly. I was lucky enough to get an appointment with Dr. Mermelstein; he was honest, candid, professional and compassionate to my situation. He suggested surgery which was the last thing I wanted to do; I’m happy I took his advice. I went into surgery with level 10/10 pain; I came out with NO nerve pain whatsoever. I would recommend Dr. Mermelstein to anyone with a spinal problem. Less

Dr. Mermelstein did my daughter's scoliosis surgery and it was a huge success. I have been bragging to everyone her before and after pictures of the amazing job that he has done.
