Everyone I came I to contact with was nice and very helpful. I could see how the office staff worked together to help each other out. If one was stepped away just even for a minute there was always someone there double checking to make sure if I needed anything. I was very impressed with the staff and the doctor as he showed compassion and concern to my case. I was very impressed how I was asked more questions than by how many questions I had to ask meaning everyone was so thorough that it leaves you knowing you are taken care of for sure.

My experience with Dr. Sam and everyone who works at Nac Neurosurgery has been an unexpectedly positive and supportive experience since my first visit. Dr. Sam is an incredibly dedicated physician who is very friendly and quick to listen, answer questions and discuss issues with me in an expedient manner. He doesn't rush to get me out of the office and I feel like the thoracic surgery went very well as did the epidural injection following the surgery.
04/18/2026
I have never had to sit and wait for longer than a few minutes to get taken to the exam room or for the nurse/Dr. Sam to be in the exam room. They have even scheduled me as the last visit before closing for lunchtime so they are able to give me a little more time for my surgery questions/consultation. I can't say enough about how well I have been treated by everyone in the office.
04/18/2026
The best nurses and other staff in this area!! So professional and caring people who truly care about their patients wellbeing and have done everything they could to ensure my experience is as positive as possible!!
04/18/2026
Dr. Sam is AMAZING and has been the driving force behind helping to improve not only my very complex and complicated spinal system but has also helped to improve my quality of life. He truly cares about doing the best he can to help me get better.
04/14/2026
Friendly , caring
04/13/2026
Dr Sam is very personable. I wish I had gone ahead with the surgery but he waited because I was improving and hoping to to better.
04/13/2026

Love Dr. Sam, he is very thorough. Instead of just jumping in and doing a surgery he is researching my scans deeply in order to make the correct diagnosis. I really appreciate his candidness and concern to get the correct diagnosis

Dr. Sam and his staff were very professional and courteous. They explained everything to me and Dr. Sam showed me the films from the MRI results to point out the areas that were concerning and why, as well as what he thinks is the best approach for treatment. Very knowledgeable and very helpful.
