Dr. Mermelstein is not perfect like he claims to be!! He took away my ability to ever return to work and took away my quality of life!! I hope you reconsider who you put your trust in to perform your surgery!

Dr. Mermelstein's office failed to call me after an aortic aneurysm was discovered in a routine MRI on my back. Mermelstein wrote a note on the report that I need to contact my physician immediately. The office didn't do that -- it was only inadvertently found when I saw another doctor. Left untreated this aneurysm could have killed me, but the office and Mermelstein, himself, remained completely unapologetic. Disgraceful, unprofessional, and certainly uncaring. I will never go to him again.

I have seen Dr Mermelstein for a consultation and I was so impressed with him and the way that he didn't push surgery upon and how we explored every other option and non operative care was the best route for me and I am feeling so much better. I appreciate his honesty and guiding me with a tailored treatment. I highly recommend him and his qualified staff.

I had a kyphoplasty with Dr Mermelstein and he repaired my fractured spine and I am so happy with the results. It came out wonderfully. His bed side manner is like no other. He always takes the time to answer all of my questions and makes me feel so comfortable. The staff here is amazing and I highly recommend him.
