Hmmm. If he wants to serve the underserved, corporate law seems like an odd area of law to specialize in.
He might not be at a firm specializing in corporate law. Or he might be there but just for the work experience. Sis told me the name of the law firm, and all I remember is it starts with a "W" and they supposedly do more pro bono work than most firms, which seems pretty charitable. I know NOTHING about law school...though a quick Google did indicate you don't need to specialize in any particular area to graduate.
