My daughter is at Pallotti in Laurel, Md. Did you consider them and write them off? Seems like a real Catholic school to me.
My daughter goes to school across the street from Pallotti. I know several of the Pallotine sisters fairly well, in fact. If she ends up going to a co-ed place, she'll probably end up going there. It would definitely be the most convenient option, without a doubt.
But in answer to your question, I have heard a couple of things about the place that do give me some concern. Freepmail me if you're curious.
