Name: William Emerson
William Emerson believes in an open corporate culture. He gives his personal cell phone number out to his employees -- all 8,500 of them. He's also led Quicken Loans in a stellar rise through the industry. When Quicken Loans was founded in 2006, it was the 34th-largest originator in the nation. Now it's originating more loans than Citigroup, US Bancorp or Bank of America, putting Quicken comfortably among the top five mortgage originators in the nation.
