Dangerous dr
He was ready to discharge me from the hospital after a week with no plan except pain medication and physical therapy. My next Dr performed surgery 4 days later due to a fractured vertebra and metal hardware already in place that was found to be broken.

Dr. Mermelstein is an excellent surgeon that takes the time to explain the procedure he will be doing and answer any questions you have. He performed lumbar laminectomy and fusion on me in 2010 and a ACDF in 2021. I am very happy with the results of both surgeries. The staff at Long Island Spine Specialists are very friendly and accommodating.

Dr. Mermelstein is a gifted surgeon, his brilliance is not just demonstrated by his skill but also by his wonderful beside manner. You can just tell after being around him that he is a not just a good surgeon he is also a good person. After being in pain for many years and seeing many surgeons Dr. Mermelstein was the first one to explain and provide a plan that was all encompassing to take away my pain. It is still so weird to go through day and especially the night without back and leg pain.

Dr. Mermelstein's office failed to call me after an aortic aneurysm was discovered in a routine MRI on my back. Mermelstein wrote a note on the report that I need to contact my physician immediately. The office didn't do that -- it was only inadvertently found when I saw another doctor. Left untreated this aneurysm could have killed me, but the office and Mermelstein, himself, remained completely unapologetic. Disgraceful, unprofessional, and certainly uncaring. I will never go to him again.

I have seen Dr Mermelstein for a consultation and I was so impressed with him and the way that he didn't push surgery upon and how we explored every other option and non operative care was the best route for me and I am feeling so much better. I appreciate his honesty and guiding me with a tailored treatment. I highly recommend him and his qualified staff.

I had a kyphoplasty with Dr Mermelstein and he repaired my fractured spine and I am so happy with the results. It came out wonderfully. His bed side manner is like no other. He always takes the time to answer all of my questions and makes me feel so comfortable. The staff here is amazing and I highly recommend him.

I felt the need to leave a review because I had seen multiple doctors for a lumbar herniated disc with onset of dropfoot. First off id like to Thank doctor Mermelstein for the successful surgery he performed on me. It was a nerve racking decision on having the surgery let alone who you were going to let cut your spine open. Amazing bedside manner, knowledgable, and well known in Huntington hospital. Im 9 weeks post op and feel great. Im getting better and better each day. 5 stars for this doctor
