Dr Dellon has been quite well known for quite a while in the PN circles.
His Dellon institute, and procedures are quite controversial.
He used to be affiliated with Hopkins, but now is independent.
He teaches his 'technique' all over the country and franchises his
Dellon Institute in many states . He has many doctors paying him royalties/fees-
and I think, pays others for referrals, as well.
Some patients have been helped, but many have not. He seems to be most successful with diabetics. His criteria to be 'accepted' as a patient is questionable.
Some say that everyone qualifies or at least that few have been turned away.
It costs to even go thru the evaluation procedure. I've heard that ins cos. won't accept his fees, so he doesn't accept insurance plans. Cash on the line.
If you do a search, here- there are 9 pages of threads that refer to him,
in one way or another. I'd read those to get some idea.
