Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

No empathy
I found Dr Onesti to be very unsympathetic and stiff. I have disc issues l4 s1 and unbearable pain when sitting. The phrase I heard over and over each visit was- Well I've seen worse Mris than yours. Don't know why you have that pain. - When I asked for his support, which consisted of filling out a three page form for disability, He had one foot out the door and talked about all the scams that occur with disability, making me feel like a criminal. He didn't think surgery was a viable option for me, and I agreed, so I don't know if he's a good surgeon.

Knowledgeable and Caring
Dr. Onesti and his team performed my ACDF surgery and the entire process was very easy. This was the first time I had to have surgery and they were all very supportive and they made me feel comfortable. I knew what to expect every step of the way and while I would have opted to not need the surgery at all I’m thankful to have found Dr. onesti and have him perform my surgery. He is very transparent and responsive. He checks in and follows up with you regularly so you never feel anxious or unsupported. I highly recommend Dr. Onesti if you are looking for a spine surgeon or doctor.

Outstanding
Dr. Onesti has been my neurosurgeon since 2005, because of him implanting the spinal cord stimulator in my back I am able to function. He is without a doubt the best at what he does & I would not let any other doctor operate on my spine. I have full confidence & trust in & with Dr. Onesti.

Fantastic Help for my brother. Now I’m turning to.
Dr Onesti is so caring and thoughtful. He discussed options for me before I may have to resort to surgery. He went out of his way to have professionals in a new procedure reach out to me. He is a wonderful doctor and a wonderful person. Thank you Dr. Onesti

Saved my dad’s life yesterday!
I highly recommend this doctor. He is very knowledgeable skilled with excellent patient care and bedside manner. He saved my dad who I brought to the ER for concerns of dementia and upon CAT scan needed immediate surgery. I was unsure if we should transfer from South Nassau to have this surgery done elsewhere, however after speaking to the doctor on the phone convinced me that he was the man and I can feel fully confident in him and South Nassau. The doctor kept In contact with me throughout his drive to the hospital directly after surgery and follow ups. I am forever grateful to have found him.

Kind and Compassionate
Dr. Onesti's receptionist is caring and efficient. The office is pleasant and my waiting time was short. Although my condition is not serious, it does have troublesome symptoms. Dr. Onesti listened and showed understanding of my complaints. He wrote an extensive report with recommendations for my other health providers. He also encouraged me to return if ever I needed to further discuss my problems.

Thank you Dr. Onesti
I had my first visit with Dr. Onesti who came highly recommended as a great diagnostician. My symptoms were vague but my pain was great. Dr. Onesti is an excellent listener and was able to interpret my symptoms and direct care. He reassured me and made me comfortable. Until meeting with him I did not feel that the other practitioners took the time to get to the cause of my symptoms. Excellent !!!

New patient
We met Dr Onesti yesterday and were so pleased. His calm demeanor made all the difference. Mom ,age 92 approaching 93 shortly, was able to understand what is going on and Dr Onesti didn’t mind repeating and rephrasing his diagnosis for her. Dr Onesti’s assistant was also very helpful and kind. I think we have arrived at the correct road moving forward

disc herniation
I have had multiple times of disc herniation that causes sciatica over the years. Dr Onesti performed the 3rd time laminectomy to take care of my disc herniation. I have been trusting him forever since every time he takes care of my issue as well as my any need so perfectly well. I mean he not only performs excellent surgery but also so knowledgeable and patient to very kindly take care of every and any of my concern.

Making an appointment was easy. A staff member called me back when she said she would. The office was clean and tidy. I was taken in on time. Dr. Onesti was nice. He listened and answered questions. This practice is pretty low tech. Rather than filling out an online form I was mailed pages of intake forms to bring in with me. My films on disc were viewed in another room so there was no opportunity to review them together. The doctor brought in a old model of the spine and pointed. Unimpressive and it makes me wonder if their medical protocols are out of date too.

Dr. Onesti operated on my mom and did an extremely good job for her. She had complications of severe arthritis involving her spine that were causing her terrible pain and making her stand and walk hunched over - and Dr. Onesti seriously improved both problems, and really improved her life by a lot. And, he treated her extremely well in addition, both before and after the procedure. He is an outstanding physician.
