"Therapy" is not a word anyone can own, just means "the attempted remediation of a health problem". If she and her clients believe what she does is helpful, then so be it.

She's interested in art and nude bodies are artful to some. Combining nude bodies "talking" could be an interesting combination; I'm not particularly into nude bodies (although I have such a painting in my bathroom :-) and not particularly into trying out this type of attempted remediation of a health problem. But I don't care if someone else does.
