5.0 star star star star starDr Marra was thorough yet patient. He did not rush me through the appointment and listened to my questions and concerns. He presented various options for my shoulder. I appreciated that he showed the problem area on my mri. He also attempted to consult another spine surgeon (rather than Dr Divi) that he is referring me to. It was such a nice and productive meeting. He told me this new spine surgeon's office will call to set up a date. I finally feel like someone is listening to me

5.0 star star star star starAfter being recommended by another highly respected surgeon Dr. Marra successfully performed my surgery. One which I was told by a different doctor had only a 50/50 chance of reattaching my rotator cuff that had torn off completely and been retracted for more than three months. And he is very pleasant.
