Finally, laws around psychedelic use and therapy vary around the world. In some places in the world (like in parts of Europe and South and Central America) psychedelic therapy is much more widely practiced above-ground than it is in the US.

A licensed therapist who does psychedelics is someone outside the norms of society while at the same time carrying a license that carries the implicit promise of following society's rules. It just strikes me as "weird" to seek that out.
Try asking around at psychedelic conferences and psychedelic meetups.
Also try contacting MAPS[1] and CIIS[2] (which has a training program for psychedelic therapists), and related organizations. Contacting people doing research in to psychedelics might also be fruitful.
