In this marketing piece for Spezzano's 2016 book tour/talking series, Vielharmonie says Spezzano is an "international renommierte Psychologe."
Chuck Spezzano is not licensed to be a psychologist. His degree was also not accredited by the APA.
If he is "internationally renowned" then why did Wikipedia reject an attempt to create an entry for him?
