This is actually old news which I have rediscovered. Julian Ticehurst, former POV trainer and employee of Spezzano and Associates Ltd. and spouse of Janie Patrick Ticehurst (co-author with Chuck Spezzano of Healing Metaphors A-Z), made the following statement on Twitter back in 2010 under his "Julian Edward" handle:
"I’d say that a good half of people who attend the groups think it’s nonsense too but they use the tools and love it for that.
even Chuck himself says that his Psychology if [sic] a hoax. But he’s not interested in people believing it. Only in the results."
