In the book Burnoutprävention für Führungskräfte by Michael Spreiter (2014) Chuck Spezzano is called a "Clinical Psychologist"--

Spezzano's 1977 Ph.D. was apparently in something exotic called
"Professional Psychology" and seems to be peculiar to the now extinct
school he attended. It was not accredited by the APA, which means his
diploma bypassed any sort of national standard. Even in Europe this
should disqualify him from being called a "psychologist." Both of the
Spezzanos are on record saying Chuck is not a "psychologist."
In
addition, Spezzano was fined by the State of Hawaii in 2004 for
impersonating a professional. He is not licensed and is not even
remotely qualified to practice professional psychology even if he
applied. He has NEVER worked as a licensed "psychologist" or published
any research in peer-reviewed journals that we can locate. His
credentials have been inflated and falsified for decades, starting with
his own newspaper advertisements in the 1980s. Here are some links to
some primary sources of interest so you can see the evidence:
