Dr. John and Dr. Yvonne are the two greatest doctors in the world. They both teach all over the world and are two of the most highly respected doctors anywhere. I live in California and have personally sent 5 – 10 patients to him(obviously all extreme neurological cases) like a patient who was shot in the eye with a BB and presented with VERY complex neurological problems that no one help him with. Dr. John figured out what to do and this 13 year old boy can now live his life normally. Their love and passion for helping improve the quality of lives is second to none. I know Dr. John has taught over 40,000 doctors and treated thousands of cases, I am honored to write their first Unilocal review. An easy 5 stars.
