I personally know Byron Richards...his office is in Edina, Minnesota - right down the road from me.
Have gone to his office a few times to get some of his supplements/lectures on Cd's. He's okay, however, very into $$$$. I have a friend who went to him to help with some of her health issues (she's on disability), and he refused her as a patient. He would only take cash, and her financials didn't measure up for her to be taken seriously.
I inquired once where they sourced their line of supplements. He refused to divulge his sources. I lost a lot of respect for the man after that.
