5 /5 sharon barnard: Dr. Chen is incredibly knowledgeable and one of the most intelligent doctors who has helped me. He took the time to teach me about my pain and help me understand that more drugs are not in my best interest. Although Dr. Chen is very kind, I do not go to him to get sympathy. He informed me about Pain Reprocessing Therapy which teaches you to perceive pain signals sent to the brain as less threatening. PRT may help to relieve chronic pain I am very grateful to him for telling me about this. Dr. Chen is generous with his time and has exemplary communication skills. He is a a doctor worth knowing.
