On working at FSG

“Step change public health progress has historically been related to surprisingly simple innovations getting traction and being implemented at scale (hand washing, use of antibiotics, immunization, family planning, etc.). The challenges associated with change management to give and sustain momentum around these simple solutions in the real world should not be underestimated. Working at FSG allows me to collaborate with outstandingly smart and motivated colleagues and like-minded change agents in client organizations to bring about the next waves of positive change in public health globally.”
