For any consumer, the warning is "buyer beware". He wasn't credentialized by any organization, except his own "institute".
I just followed a recommendation from a minister, so I acted on the "word of mouth", instead of looking for an organization with standards. And I was naive.
Maybe now, after many years, I have the courage to speak to that minister, to speak to him about the abuse. Somebody actually put up a website after his business partner was charged with sexual abuse allegations. No-one responded, since guilt and shame are used by shady shamans for control.
But then, you can look to many other industries like the financial, to see dishonesty, too.
Ask the facilitators for help, and they'll steer you in the right direction, and be patient.
