On Working at FSG
"I am at FSG because it allows me to work on some of the world’s most pressing problems together with people who have big brains AND big hearts and are deeply committed to social impact. I have always cared passionately about social justice and the state of the world and felt a responsibility to contribute my skills and expertise to making things better. FSG gives me the opportunity to do that while offering me an extremely stimulating environment thanks to the energy and intellect of the people I interact with on a daily basis."
