Never would recommend Dr. Masami Hattori, not even to my enemies. I have severe chronic pain, I was under his care for almost four years, the whole Time bedriden He is afraid to prescribe pain meds because he says he will loose his job. I have a fussion in my lower back, I also had a herniated disc bulge removed and I also fractured 17 vertebrates. My back collapsed and is now cemented from my tail bone to my neck. He will not prescribe over the Fda recomandation even white exceptions. zero.

DR. Hattori is a Dr. that really listens to you, his authorizations for medications and new Doctors are timely and I get results fast. He is the most kind,honest,timely DR. that I have ever had the pleasure to meet. I absolutely love him. He has changed my life.He Has kept me functional and working,which is the most important thing for me. You will not be disappointed if you choose him for your Dr.
I have never before or since had a physician inflict so much unnecessary pain. If he had just injected anesthetic with the steroid it would have been tolerable. But he wanted pics he could brag about to his students so he left me laying on the table in agony while he bragged to the tech with him that day. My advice to anyone referred to him is run the other way as fast as you can.
