Takes time to talk to you as a friend

Great experience with Dr. Frauwirth. Takes time to explain exactly what’s going on. Very friendly and attentive to your issues. Takes time to talk to you as a friend, just not another patient. Highly recommend him for any orthopedic and pain needs!


I am very pleased with the excellent care

Dr. Dowling is a phenomenal doctor. He always takes the time to answer all of my questions and he is a very skilled surgeon. I am very pleased with the excellent care that I receive here from Dr Dowling. I highly recommend him, he is very trustworthy. There isn't a better surgeon around. All of the Physicians and Staff here are all so wonderful they are all so helpful, knowledgeable, polite, smart and always so kind.


They treat you with respect

From staff to the doctors Long Island Spine Specialists are as professional as you can get. They treat you with respect! Others in the practice should emulate them. I had the pleasure of meeting Dr. DeWal and he is a true MVP doctor and a great human being. I’m so grateful. Thank you!


The level of care given by the staff was fantastic

I took my grandfather to Long Island Spine Specialists to treat nerve pain originating from his back. The level of care given by the staff was fantastic. Dr. Sanelli provided the best bedside manner to my grandfather that I have ever seen from any of his physicians. Highly recommended!


A good experience with no problems

Dr. Basra operated on my spine. I had a couple of bad bulging discs, he always was great at answering questions and always had a smile. This is great patient care and with an operation on my spine where a mistake can be terrible this has been a good experience with no problems!


Office staff is so nice

Dr. Mermelstein is a great surgeon and has great bedside manners! Office staff is so nice and very helpful on the phone. Would recommend to anyone.


The staff is very friendly

Dr. DeWal did my lumbar fusion and I am feeling a lot better. He was very professional and very knowledgeable, he took the time to answer all of my questions and made sure I understood everything. The staff is very friendly and I highly recommend him for anyone having spine surgery.


Top notch in all they do

I couldn't ask for better doctors and staff to not only work with but to also treat me for a back condition related to an accident. I am so blessed to have found Long Island Spine. They really are top notch in all they do.


So pleased with my visits and care

The practice is excellent and Dr. Sanelli is great! It has been a long time and I have always been so pleased with my visits and care.


Great office staff and doctors

Excellent experience, great office staff and doctors. Highly recommend!


The staff at LISS were all fantastic

Dr. Frendo and the staff at Long Island Spine were all fantastic. Dr. Frendo did a great job of explaining my procedure and he made all my fears of surgery go away. Post-surgery and my pain is gone. Thanks Dr. Frendo!

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

Long Island Spine Specialists, P.C. is proud to be the first spine practice on Long Island to utilize the Airo® Mobile Intraoperative CT, designed for diagnostic imaging and intraoperative use, at St. Catherine of Siena Medical Center.

"With the new imaging equipment, we are able to react intraoperatively to the surgical situation by verifying what has been done after each step, potentially correcting any imperfections during the procedure." - Dr. Dewal

The Airo is designed for use in the Operating Room (OR), and provides diagnostic quality images, giving surgeons more precise and up-to-date anatomical information during surgery for timely and informed decision-making. Utilizing the latest in imaging technology, Airo, the portable 32-slice CT scanner, has the potential to change daily life in the surgical space, offering mobility, flexibility, and access to real-time patient images, aiding decision-making in the operating room.
