Chuck Spezzano is graduated to the level of "MD" in the Aeclectic Tarot Forum, July 2010:
"Archetypes and Shadows by Chuck Spezzano. I love the cards. I'm not
usually into oracles but I find these cards intriguing and relevant. I
may well end up working with them :)"
"Chuck Spezzano is actually an MD and specialised originally in philosopy
[sic] and psychology, moving on to sociology and counselling psychology. His
aim in writing the book was "to provide quick and effective ways to
find, understand and move beyond the bane of our shadows, and to enable
us to use the power of archteypes to accelerate our growth". There are
exercises and ideas in the book."
Chuck Spezzano is not a medical doctor and he is not a psychologist.
