Another First for Long Island Spine Specialists, P.C.

Long Island Spine Specialists, P.C. continues to be on the forefront offering our patients the most technologically advanced spinal procedures. We are proud to announce that LISS is the first on Long Island to perform a minimally invasive interbody fusion with intraoperative navigation.

Very few surgeons across the nation perform this procedure which takes additional training and expertise, which sets us apart. This procedure leads to less blood loss, decreases hospital stay, lowers complications, and increases the accuracy and precision of screw placement, as well as a reduction in radiation exposure to both the patient and OR staff.

We are committed to excellence and will always offer our patients the best options available.

Our Mission

At Long Island Spine Specialists, P.C., we know how debilitating back and neck disorders can be for our patients. We also know that when it comes to treating these conditions, finding the treatment option that best meets each patient's individual needs is perhaps the most important aspect to successfully alleviating or managing back and neck pain.


"Dr. Mermelstein was selected to perform a 4 level fusion and Laminectomies on my back in July 2007. I chose Dr. Mermelstein after visiting with many highly recommended surgeons (primarily in Manhattan). Dr. Mermelstein’s plans for me as well as his assurance all came to fruition. Post –surgery medications, braces and physical therapy eventually improved the quality of my life immensely. From age 19 to 62, I suffered continuously. I used Naprosyn for 25 of those years (1,000 mgs per day). Now I do my exercises daily and I play a lot of golf!! I can walk long distances and at age 69, I just returned from a successful climb of Machu Picchu in Peru."

Sincerely, Melvin N.

"Dear Dr. Dowling, As I go through each day newly pain-free, I think how fortunate I am to have come under your care. I truly believe that you've given me my life back and I'm deeply grateful!"

Sincerely, Marianne K.
