Hiya,
I'm one of the ortho interns at Pitt. Call Petie Bigenho @ (412) 605-3267 or e-mail her at [url=mailto]bigenhol@msx.upmc.edu[/url]. She'll know of residents that can put you up. Or if there's no one who can, start looking online somewhere for sublets. I think there are some sites online but I don't remember what they are.
