Facebook Chief Operating Officer Sheryl Sandberg (pictured) resigned from the board of directors at eHealth Wednesday “so she could devote more of her time toRan personal and professional obligations,” according to a filing the online health insurance company made Friday announcing her replacement on the board, Stanford Chief Financial Officer Randall Livingston.

Sandberg once served as chief of staff for the United States Treasury Department during the Clinton Administration under Treasury Secretary Lawrence Summers, who has been named President-elect Obama’s chief economic advisor. Between Treasury and Facebook, she worked at Google, serving as vice president in charge of online sales and operations. She was also instrumental in launching Google’s philanthropic arm, according to her Facebook bio.
