oritz vs pompa ???

I've been doing tons of research on VSG and thought I had my mind made up with Dr. POMPA.  I've since found the OCC website, and it looks fairly similiar to LIMARP.  I'm looking for any info on Dr. ORITZ and his facility.  The forum on the OCC website is of course biased, and I haven't been able to find much on OH regarding OCC.  You can PM me if you dont wish to post on here.  Thanks!
