Does anyone know anything about who this guy actually is? 
History, education, training....even just his real name?   He claims to be a doctor. If he wants to brandish the credentials of authority then show them to people. He used to be an ion machine salesman, then tried to delete all traces of that on this site before returning as a neigong guru.   It is very suspicious to conceal one's identity when asking people for money. It is a huge red flag to ask people to trust you with their spiritual health while deliberately concealing who you are.
