Dave,
Hi.
If he was not licensed in Utah that is certainly a problem (but does not mean he has no expertise in the areas for which he may be licensed elsewhere). And, what he actually advised the woman is not necessarily the same as 'diagnosing' anything. What, exactly, he actually advised her is not clear from that article either. To suggest that he 'diagnosed' beyond his expertise is, I woud say a matter for the evidence and whatever legal investigation there will be.
However, I am not about to charge and convict him here based on one internet article.
Cheers,
RC
