While Dr Beyer talks a very good game, your money will not be well spent. He does an extensive and expensive bank of testing up front and talks about a course of therapy and supplements. He promised several forms of neurological therapy, but most were never delivered and those that were often required correcting the indifferent office staff(e.g. right, not left). He also recommended extensive supplements, the vast majority of which can be purchased directly from Amazon at half his prices. Overall, I did not experience any real improvements or changes other than a significant drain on my wallet and time. Please save yourself both: get off gluten, sugar and processed foods, get 8 hours of sleep a night and eat more organic meats and vegetables. It’s pretty much all the positive advice for which Dr Beyer will charge you several thousand dollars.
