On working at FSG

“I wake up every morning excited to get to work. I love FSG’s entrepreneurial and caring culture, and our dedication to finding better solutions to tough social problems. My father served in the military, and as a child I had the opportunity to travel extensively and to witness first-hand dire poverty, as well as the incredible strength and resilience of my fellow human beings—an experience that set me on a course to work towards social change. At FSG, I am inspired and energized by the opportunity to work with bright, talented colleagues and clients who share my passion for making a difference in the world. I have had the opportunity to work on a wide variety of issues over the past ten years at FSG, from microfinance in Africa to increasing post-secondary attainment in the US to reducing poverty in rural communities. Most recently, I have been excited about the opportunity to build stronger cross-sector partnerships around key social issues to achieve greater collective impact.”
