Founders and Board of Directors:
Sarah Hillware, Founder and Board Chair
Sarah is a longtime champion of women's and girls' empowerment, as she believes it is central to poverty eradication, community empowerment and economic growth.
She recognized a growing need for health education in the school system, and began researching the topic in-depth while studying at The George Washington University. Upon receiving a small grant, she piloted health education workshops in Washington, DC, and also performed secondary research in other low-income communities throughout the US, as well as Kenya and India. What she found was a missed opportunity to empower adolescent girls during a critical window of time, and it inspired her to formalize her operations and establish Girls Health Ed. Sarah strongly believes in the power of education and the power of women. Through her global studies of public health, and her personal and professional experiences, she has learned that the empowered girl is unstoppable.
