hahaha I can relate to that you could try looking him up on your state's licensing website?
Also, i think if he's putting it out there that he only does a limited practice, that is like totally leaving it open for you to say, 'what does a limited practice mean'? and if he says something fishy, you will know. But since's he's stating it outright...I bet he doesn't have any weird things going on...B/c if he had been in trouble or something before, surely he wouldnt' want to advertise it like that? Or maybe ....
Hmm speculation gets me into trouble. I'd just ask him. Or if he has a secretary? I find they are wonderful sources of basic information if i feel like i dn't want to bother T about something small..
