@Fenwick You are correct, to operate under the title of clinical psychologist, you need doctorate in psych (ph.d or psy.d) and have done all the licensing requirements for your state.
You could also practice with a Master's degree with a degree in social work (Master's of Social Work or MSW). Historically MSWs take on less serious work than full on doctorate shrinks.
However, the the term "therapist" isn't a licensed term. It's used interchangeably, but technically anyone can call themselves a therapist. As long as you're not telling people you have a doctorate, or try and take insurance or are passing yourself off as the real deal, you can charge people for advice. I guess it's like consultation.
But yea, you could technically rent a space and charge people for advice, so long as you're not claiming to be a psychologist.
If he's claiming to be a ph.d then he's in trouble, since his degrees are not valid and I'm sure any "clinical program" he did is not APA accredited.
I don't know what his undergrad uni is, but I've never heard of that degree. Typically you get a B.A or B.S. in general psychology and possibly a certificate if you take certain classes (and honesty, most undergrad psyc certificates don't seem to do much). You could do a Bachelors in public health or something similar, but I have no idea what the hell his "degree" would even mean since, as said, you can't really do anything legit in the psyc field with just a B.A/B.S.
