I've been looking into this also. However I'm already doing the work without the certification and I"m making the same that they claim to make. I spent 7 years as a DON and learned to do most of what they claim to teach in the program.
To me the programs out there are geared to generate revinue not actually help as a proffesion. Non of the Lawyers I work with require the cert and a few have actually laughed at it. But putting that in perspective, people respond that way to what they don't understand.
