First - each patient is different - different expectations, circumstances and reactions. Dr. Hammerstein met w/me prior to my operation (both neck and spine) and thoroughly explained the procedure. There was never any rush or unintelligent question from me. He is very caring, gentle, understanding and professional. After the surgery, it was clearly explained to me my limitations, and expectations. I followed those instructions "to the letter" and my results were better than I anticipated. I believe anyone who does not have the excellent results I have might not have followed those instructions. Prior to surgery - I was in horrific pain - I have never felt better than I do now - thanks to Dr. Hammerstein and his staff. It is always wise to have references prior to submitting to surgery with any doctor. I recommend Dr. Hammerstein fully. He and his staff cared for me as though I was the only patient they had. His staff reflects how he treats them...and they are also excellent and very caring.
