I often do call myself a: Modern Mesmerist.
I just keep away from steel rods and don't allow anyone to enter the tub of water until I feel they're totally cured.
Thaumaturge, though I think the Greek root "thaumatourgos" sounds a whole lot better when spoken.
From etymonline.com:
thaumaturge
1621 (implied in thaumaturgical), from Mod.L., from Gk. thaumatourgos "wonder-working, conjurer," from thauma (gen. thaumatos) "wonder, wonderous thing," prop. "a thing to look at" (from root of theater, q.v.) + ergon "work" (see urge (v.)).
Eh, I really doubt I would actually call myself that unless I was practicing back in the 1600's, going to great lengths to avoid the greater Salem area. :-)
