Dr. Spivak did a phenomenal job in regards to my back surgery, I have had 10 surgeries in my past and I feel that this was the smoothest procedure. I was very appreciative of his timeliness in regards to getting y surgery done, as well as performing the surgery in a manner which caused me no discomfort. I would highly recommend him to anyone. If a person is in need of the services that Dr. Spivak offers, you would do yourself a major service by going to him. I want to thank you again for your professionalism and execution of my procedure.
