After having surgery and going to a pain mgmt specialist for # 1/2 years this past February 2018, I went to Dr John Cassidy. He saw me within a few days, ordered an MRI (which my other Dr's never thought of) ,he reviewed the MRI within a day. Told me to come in and he thoroughly went over the surgery I needed. Within a few days his office got the insurance pre-authorization and I had the surgery at Doctors Hospital. I couldn't believe how smoothly eveyrthing went! My back feels great now.

Both Dr. Cassidy and Dr. Guerin are the best Neurosurgeons in the area! I wouldn't trust anyone else to be in my spine or brain. Thanks to both of them for fixing me up to where I could walk again!

Dr Cassidy read my X rays and found the cause of my tremendous pain in my left leg was a pinched nerve. IL was living on 5-6 pain pills daily. He is the one who spotted that the cause was a cyst that was growing and eating the vertebrae and pinching the nerve. After he removed the cyst I was pain free and have been for two months now. His patient relationship was very personal and caring.

I have seen Dr Cassidy due to ongoing cervical and lumbar disc pain. He ordered a 3 tesla MRI. I was amazed! After several years of poorer MRIs, he knew right away what the problem is and how to fix it. Not only that, my doctors highly recommend him. I'm only awaiting my own home arrangements for surgery. I can only say thank you to this man.

I saw Dr. Cassidy because I was having sciatica in my left leg with severe back pain in the same area where I have a repaired herniated disc. He sent me for an MRI and read the films himself with me and my husband in the office with him. He found the problem (spinal stenosis) and we discussed my options. We were in agreement that an outpatient surgery would be the most likely best option for me. I had the surgery and within the predicted month, was feeling fine! Pain gone. Happy camper.

I have had numerous dealings with Dr.Cassidy for mainly cervical and lumbar issues. He is always willing to answer any questions you want to know. He is on the quite side, but will open up you just have to ask. Very respectful and professional. I am spoiled and would prefer to have him to perform any further issues that may come up down the road for me within his field of specialty. Caring and dedicated Doctor.

In 2013 Dr Cassidy fused L 4 and 5. My pain was much worse after surgery and dr Cassidy was so had to talk to I finally gave up. My pain got so bad I could not walk across the room. Had surgery at Vanderbilt Nashville Tenn October 2015. It was an 8 hour surgery as I had a lot more problems then Cassie diagnosed. I am now pain free. Cassidy did not take the time to give me the proper care I needed.

I had a severe back pain. It had caused such pain I did not think I would ever recuperate. I learned of Dr. John Cassidy through a friend and thought I would make an appointment. I had the spinal surgery and I was 100% free from pain. My neighbor down the street also has needed surgery on the spine. I shared my experience with this neighbor who was in back pain and he had Dr. Cassidy perform back surgery on him too. No More Back Pain...no more walker...no more cane. Walks the dog again. D.Swat
