Susan Roos wears many hats. A mother of two and the wife of U.S. Ambassador John Roos, she is also a partner at Cook Roos Wilbur LLP in San Francisco, where she practices as a labor law attorney.

And since her husband took up his post in Tokyo in August 2009, Roos has divided her time between Japan and San Francisco as a full-time mother, lawyer and ambassador's wife.

At a recent international symposium titled "The Next Stage: Families that Work!" organized by the Soft Landing Task Force of the American Chamber of Commerce Japan's Corporate Social Responsibility Committee, Roos said she didn't want to make a choice between having a career and having a family — she "wanted to have it all."
