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.

Horrible! Doesn't listen to patients. Pushes heavy drugs, surgery, and toxic steroids. Arrogant, rigid, and full of ego. Rude, unable to articulate himself. Rushes appointments and thinks everyone fits a cookie cutter. Does not trust or respect his patients. Hostile and neglectful.
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.
