Michelle Obama's office said Kristina Schake, a Los Angeles-based PR executive and former aide to California First Lady Maria Shriver, was named its new director of communications.
Schake replaces Camille Johnston, who left the White House in August when she was named VP of corporate affairs at Siemens.
The White House cited Schake's work on child nutrition and community health issues, as well as her background in a military family, as two attributes that Obama found important. In the last year, Obama has targeted obesity issues, launching the "Let's Move" campaign and talking to the industry about developing healthier foods and beverages.
Before founding a political consulting firm, Griffin Schake in Los Angeles, she served as director of the Governor Arnold Schwarzenegger's Summit on Obesity and communications director for First 5 California. Schake also worked at GMMB for several years.
PRWeek profiled Schake in 2007, following her work on Live Earth. You can read the profile here.
