On working at FSG

“Early in my career, my work and travels as an international development consultant exposed me to broken systems that undermine and thwart the enormous human potential that exists around the world and the daunting challenges donors face in both understanding those barriers and making a difference with limited resources. At FSG, I advise leading organizations—in the public and private sector—on how best to tackle these challenges. I draw on my prior corporate strategy consulting experience to lead executives, teams, and collaboratives in identifying, developing, and executing practical, evidence-based strategies for greater societal impact. I deeply believe in FSG’s role in influencing and shaping social change.”
