Patty Stonesifer, former chief executive officer of the Bill & Melinda Gates Foundation and one of the world’s most prominent philanthropy professionals, is taking over leadership of a Washington, D.C., food charity, The Washington Post reports.

She will begin work April 1 at Martha’s Table, a 33-year-old Washington charitable institution that provides meals for the homeless and services for low-income families. The nonprofit group has 81 employees and a budget of $6-million, a far cry from the 500-plus employees and $39-billion endowment at the Gates foundation when she was the leader.

“If you just look at my résumé, I find that I have to explain this,” said Ms. Stonesifer, a former Microsoft executive who left the Gates Foundation in 2008 and currently chairs the White House Council for Community Solutions. “But if you know me, I don’t have to explain it at all. I absolutely think I can help Martha’s Table, but this is going to be wonderful for me.”
