Company: Mylan
Fortune 500 rank: 396

Involved in a 2008 scandal involving an MBA she technically didn't earn, Bresch kept a relatively low profile. As the daughter of U.S. Senator (and former West Virginia Governor) Joe Manchin III, her missteps were splashed all over the media. She's never openly discussed the events, but her silence may be her best advice yet. Keeping calm and carrying on, Bresch held her head high and went on to become Mylan's CEO last October.
