Susannah Meyer

The tight-knit, girls’ school environment that Hewitt fostered around me for 13 years gave me the confidence and drive I've needed to pursue my interests without hesitation, stay curious and open-minded, and prevent gender barriers from blocking my goals.

Susannah Meyer '15 is majoring in computer science at Stanford as a member of the class of 2019. She has held software engineering internships at JP Morgan Chase & Co., Bloomberg LP, and Facebook. At Stanford, Susannah is the webmaster and technical team lead of the student publication The Stanford Daily and will begin research at the university's virtual reality lab this fall.

Hewitt showed me the value of seeking achievement not for achievement's sake alone, but because living a life of consequence, and recognizing that my actions, whether positive or negative, intentional or unintentional, impact the lives of others. I am discovering the ways in which my actions can contribute to making the world a better place.”


Sofia Caballero Stafford ’13 studied Global Health and Cultural Anthropology at Duke, earning her AB in 2017. In 2016, her team won the $10,000 Grand Prize in the Duke STEAM Challenge to fund the development of "Pocket Counselor: Health in Hand," a mobile application designed to help task-shift mental health counseling to lay practitioners in Kenya. Sofia also found purpose in her internship with USAID working on the Saving Lives at Birth: A Grand Challenge for Development. After graduation, she moved to D.C. and is currently working at USAID through the Global Health Fellows-II program. While at Hewitt, Sofia initiated what would become a multi-year partnership with Girl Up, a campaign of the United Nations Foundation and a community of nearly half a million passionate student advocates focused on girls living in places where it is hardest to be a girl.

Diana Marin

Hewitt, a place that shaped me and which I love, taught me where to find my anchors. Faith and courage don't originate in external movement and action. They're anchored in the deep rooted sense of who I am. Serving on the Alumnae Diversity Committee is a way for me to honor these roots and to strengthen them with the ever-growing Hewitt community.

Diana Marin is completing a self-designed Master's in Divinity through the Open Master's program. Her study centers on the themes of roots, courage, and vision as pillars in community-building.

She went on to have a 20 year career in event planning in a variety of industries before pivoting to a career in real estate.

Hewitt first introduced me to the concept of community service when I became a weekly nursing home visitor at Mary Manning Walsh Home, and I remained a volunteer there throughout college.

I have passed this tradition on to my daughter as well.
