Washington, D.C., and Williamsburg, Va.—GuideStar, the leading source of nonprofit information, welcomes DonorsChoose founder and CEO Charles Best, Google director of global online help Sophie Bromberg, and Hewlett Foundation Philanthropy Program officer Jacob Harold to its board of directors.

"I am delighted that Charles, Sophie, and Jacob accepted our invitation to join GuideStar’s board," said Bob Ottenhoff, GuideStar’s president and CEO. "They bring valuable perspectives and rich experiences that will make our already strong board even more effective."

Charles Best founded DonorsChoose, a Web-based nonprofit that enables individual donors to fulfill needs and foster innovation in public school classrooms, while teaching at Wings Academy in the Bronx. Since its inception in 2000, DonorsChoose has delivered $36 million worth of resources to 2,240,000 students and won numerous awards. First Lady Michelle Obama described DonorsChoose as "exactly the kind of social innovation and entrepreneurship we should be encouraging all across this country."

Sophie Bromberg is an expert at leveraging technology for results. Before joining Google, she was investments director at the Omidyar Foundation, the social venture firm funded by eBay's founder; senior director, global trust and safety, at eBay; a manager at the Boston Consulting Group; and a financial analyst at Goldman Sachs.

Jacob Harold has led grantmaking for the Hewlett Foundation's Philanthropy Program since 2006. In that time, he has overseen $25 million in grants which, together, aim to build a 21st-century infrastructure for smart giving. He joined the foundation from the Bridgespan Group, where he served as a strategy advisor to nonprofits and foundations. Before that, he worked as a climate change strategist in New Delhi, India, for the David and Lucile Packard Foundation and in the United States for Rainforest Action Network and Greenpeace USA. He began his career as the organizing director for Citizen Works and spent a year as a grassroots organizer with Green Corps.
