In this commercial marketing for a Chuck Spezzano card set, Ex Libris says Spezzano earned a Ph.D. in "Clinical Psychology."

Yet again we must point out this is false advertising.
Spezzano's 1977 Ph.D. was apparently in something exotic called "Professional Psychology." 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:
