I went to the website and Delucia has a response to the aiki forums questions.
One warning light that has been pointed out before, is the lack of credentials. All references are vague. And no teachers are directly mentioned. That to me speaks volumes.
He maybe a good teacher, but if you dont supply a detailed history citing previous teachers and awards, thats sound very suspect. That casts a serious credibility shadow over what he is trying to do.
I am not attacking the fellow, but I ve always been taught to research before you train.
