I was in pain for months and thank goodness I was referred to Dr. Onesti. The office was professional and Christine was amazing! My treatment plan was discussed in depth and I left with a course of action. Not rushed and overwhelmed like other practices. Excellent experience!

My first visit with Dr. Holtzman was amazing! He took the time to explain my condition in great detail. He also provided me time to ask any questions. He is compassionate, knowledgeable, and friendly.

Amazing office staff, always helpful and kind. Dr. Snyder always takes time to really listen and not only offers his patients options, but takes the time to explain the outcomes of each choice. I have always found Dr Snyder genuinely cares about his patients. I have had multiple surgeries with him and feel comfortable and confident in his surgical skills. His secretary Michelle is always quick to respond to any questions always cheerful and helpful.

Dr. Gaudin is truly a professional and experienced doctor in his practice. I must admit that I was very nervous to undergo my procedure, but with his support and guidance, all went well and I am currently on the road to getting back into life. The entire process was hassle free and I would recommend his expertise to anyone who is seeking to undergo any procedure under his guidance.

My name is Patricia K Mack & I've been a patient of Dr. Stephen Onesti since 2005. He is a fantastic surgeon, a very caring & compassionate doctor. He goes out of his way to make you feel comfortable as a patient. I'm very pleased that he's my neurosurgeon and trust him implicitly with any surgery he's doing on my back. The spinal cord stimulator he put in my back has worked like a charm since 2006.

Now I need a upgrade to the battery in my stimulator & Dr. Onesti is the only neurosurgeon that I'd want to do my surgery. All of his staff are also top notch & go out of their way to make sure everything is done completely & professionally.

Dr. Michael Brisman was very caring and attentive as always. He answered my questions and made me feel very confident. Julie returned phone calls immediately, and made sure that all my paperwork and approvals were ready when I came for my appointment. Dr. Brisman and Julie are a very professional team and they made it a stress-free experience.

I first came to NSPC and Dr Vaynman for a second opinion. I quickly decided that his thoroughness and care were the what my spine deserved! From Liz greeting me like family, in person and on the phone, to the care and reassurance at every step of Dr Vaynman, I knew I was in the right hands. My care has been fantastic and I knew every day that I was in the hospital, I would see Dr Vaynman. He assembled the perfect team of other physicians to ensure my surgery went as smoothly as humanly possible. I have already referred 4 other people to this office.
