Technology and Leadership
Stonesifer’s first leadership position was as the head of Microsoft Canada; afterwards, she rose in the ranks at Microsoft, becoming vice president of the company, revamping many of the company’s fundamental operations, and overseeing the company’s $800 million interactive media and online content division. During this time, Stonesifer created and managed products including Microsoft Encarta Encyclopedia, the Magic School Bus games, and MSN. She also consulted for DreamWorks, and negotiated a joint venture between the companies in 1996.
After her successful tenure at Microsoft, Bill and Melinda Gates appointed her to lead their philanthropic foundation. The Gates Foundation uses its $38.7 billion endowment to improve public health and educational opportunities around the world. Stonesifer was the CEO of the foundation until her decision to step down in 2008.
Feeding Families with Martha’s Table
In 2013 Stonesifer was named president and CEO of Martha’s Table, a D.C.-based grassroots charity that provides food, education, enrichment programs, and financial help to families in need. The charity runs preschool and after-school programs for children, some of them homeless, and helps their parents put food on the table. Martha’s Table is mainly staffed by volunteers, including Stonesifer, who will not accept a salary for her work.
