Gabby Giffords, emphasizing mental health, trauma support, and voter engagement. Corin also helped build out March for Our Lives’ chapter program, which connected thousands of young people across the country in local organizing efforts modeled after the Parkland students’ activism. By 2019, hundreds of chapters had formed nationwide, serving as a core part of the organization’s grassroots infrastructure. After graduating from Marjory Stoneman Douglas High School, Corin enrolled at Harvard University in 2019, where she studied Government. During this period she stepped back from day-to-day organizing to focus on her education, but remained involved as a strategist and spokesperson. Corin served as one of the organization’s public spokespeople, promoting the march through national media appearances. In June 2022, she was interviewed on
The Tonight Show Starring Jimmy Fallon to amplify the group’s demands for federal gun safety legislation. After completing her undergraduate degree at
Harvard in 2023 and later pursuing graduate studies at the
University of Oxford, Corin returned to March for Our Lives in a formal leadership role. In March 2025 she was named Executive Director of
March for Our Lives, overseeing both the March For Our Lives Foundation, a 501(c)(3) focused on education and community programs, and the
March For Our Lives Action Fund, a 501(c)(4) advocacy arm. In this capacity, she has led a major organizational restructuring and strategic planning effort. In 2025, Corin and March for Our Lives launched a campaign against U.S. Attorney General
Pam Bondi, criticizing what they described as her hypocrisy on gun violence and her role in rolling back federal gun safety progress. == Works ==
