I highly recommend Dr Greenberg. I was in a terrible fall onto concrete. There was no such thing as a "3 Disc Replacement" at this time. I was cared for by some of the best doctors, but after 5 years of living like this, I was on a high amount of pain meds. Dr Greenberg was able to take me down to 2 pills for my spine and a few for my leg. I returned back to Dr Greenberg in 2015. What I appreciate is Dr Greenberg took the time to research my med history. He is compassionate. If you're new know he is focused and cares.
