Elizabeth Lee Agosto, a deeply cherished member of the Dartmouth College and St. Mark’s School communities, passed away on November 1, 2024, following a sudden medical emergency. Her unexpected death has left a profound impact on those who knew her as a dedicated educator, a compassionate mentor, and a committed advocate for students. Born in the Bronx, New York, and later a resident of White River Junction, Vermont, Liz Agosto brought a passion for education, equity, and student engagement that spanned her career and touched countless lives.
Agosto’s journey in student advocacy began with her own undergraduate years at Dartmouth College, where she graduated in 2001 with a degree in sociology and a minor in education. Known for her commitment to social issues, Liz was a leader on campus, serving as president of the Casque and Gauntlet Senior Society. Her early involvement with student groups reflected a lifelong dedication to creating spaces where students, especially those from underrepresented backgrounds, felt seen, heard, and supported. Her role at Dartmouth set the foundation for her work as a staunch advocate for student well-being and inclusivity throughout her professional life.
Upon completing her master’s degree in sociology at Fordham University, Liz returned to Dartmouth in 2007 for a temporary position at the Collis Center for Student Involvement. However, her dedication and impact were so evident that she was soon offered a permanent role as Associate Director. In this role, Liz co-created the First-Year Student Engagement Program alongside Samantha Ivery. This initiative, aimed at supporting first-generation college students, drew the attention of Charlotte Johnson, the then newly-appointed Dean of the College. Liz’s efforts with the program demonstrated her unwavering commitment to student support and success, leading to her appointment as Special Assistant to the Dean.
Throughout her tenure, Liz mentored countless students, guided new leaders within Student Affairs, and left a lasting mark on Dartmouth College’s community. Her colleagues and former students remember her as a thoughtful and brilliant educator whose empathy and insight inspired all who worked alongside her. Liz’s legacy of care, leadership, and advocacy remains a touchstone for those who strive to continue her work within student affairs and education.
After Dartmouth, Liz joined St. Mark’s School as the Dean of Students, where her dedication to nurturing student growth and well-being remained central to her work. Her influence reached far beyond the administrative roles she held; she became a trusted figure on campus, recognized for her commitment to helping each student realize their full potential. At St. Mark’s, Liz was instrumental in building connections between students and staff, fostering a community where everyone felt valued and supported.
Friends, colleagues, and students remember Liz as a true advocate for those who felt marginalized or underrepresented in educational spaces. Her mentorship impacted many, providing guidance and support to young leaders, current students, and alumni alike. The Dartmouth community, St. Mark’s School, and those who knew Liz across her career continue to express their sorrow and extend condolences to her family. Plans for remembrance services are expected to be shared in the coming days.
Beyond her professional achievements, Liz was known for her kindness, her warmth, and her belief in the transformative power of education. Her sudden passing has left a significant void, and both Dartmouth and St. Mark’s are honoring her legacy by encouraging community members to seek comfort together. Colleagues Anne and Eric reflect on her influence by stating, “Liz’s impact on our work, our relationships, and our love for Dartmouth endures to this day. We will miss her dearly and hold her memory close as a source of inspiration.”
Funeral arrangements for Elizabeth Lee Agosto will be released by her family. In honoring her memory, St. Mark’s and Dartmouth College invite those touched by Liz’s life to come together, share stories, and reflect on the lasting legacy of a woman who championed inclusivity, student welfare, and the belief that everyone deserves a place to thrive in educational spaces.
