It's Donald Trump's White House, but there will be plenty of people helping him work in it.

Now that he's been sworn in as President (You're Fired 'President-elect' moniker!), Trump can officially call together his cabinet to do the nation's work. And while his selections have yet to be officially confirmed, the new Republican majority in the Senate makes it likely that the majority -- if not all -- of his picks will be approved.

Though many of Trump's incoming advisers are familiar figures to traders, like Wilbur Ross, Steve Mnuchin and Anthony Scaramucci, many others are less well known on and off Wall Street. That's why TheStreet has prepared a primer on some of the people that will soon be driving policy in Trump's brand new boardroom at 1600 Pennsylvania Avenue.
