Priscilla Chan: Much More Than A Billionaire's Housewife :)

Facebook CEO Mark Zuckerberg and his new wife Priscilla Chan were not waiting for the big IPO to get married — they were waiting for Chan to finish med school. Zuckerberg attended her graduation recently and even "checked in" via Facebook, writing: "I’m so proud of you, Dr. Chan :)." Chan, anything but a stereotypical billionaire's wife according to Forbes, will start her job as a pediatrician later this year.
