I am also confused, but intrigued. Dug on Nyquist a little just now, found nothing but the usual doctor-review sites (shitty customer service, apparently, and pts rarely actually see Nyquist.)
That nothing may be interesting in itself; I've looked into a lot of psychiatrists over the last few months, and it's the same story with every damn one of them–they only exist on the internet as a business.
No farcebook, no linkedin–nothing. They don't even show up as algo-generated bait in the mylife/intelius ads. Every one I've looked into so far has been a ghost.
