Sara’s work connects educators, civic leaders, nonprofits, universities, and technology innovators to create scalable models that expand opportunity. Her vision is to transform education into a platform where creativity, leadership, and innovation are not extras but essential tools for a just, vibrant, and inclusive future.

Outside of work, Sara enjoys spending time with her husband and three children, as well as golfing, writing, skiing, painting & dancing, and building meaningful connections.

Nina Nedrebo

Program Manager

Nina Nedrebo (MBA, Ed.M) brings a decade of community-centered programming experience to improve children's educational and life outcomes. At 23, as a political representative in her native Oslo, she discovered the joy of pathways to systemic change when, having spent time in Sahrawi refugee camps interviewing women and children, her resolution to improve Norwegian foreign assistance policy towards the Sahrawis displaced to Algeria was adopted by her party.

Her commitment to children grew while serving as an educator in Norwegian public schools and advocacy intern with UNICEF Norway. She went on to co-chair an international development NGO Summit at the University of Minnesota Humphrey School of Public Affairs and oversaw human resources and payroll for 90 staff at St. Michael's Catholic Church and School in Prior Lake, MN, before becoming a 5th grade math teacher through Teach for America Massachusetts with Holyoke Public Schools.

As a full-time mother, her vision for child-centered public service came into focus while a Zuckerman Fellow at Harvard Kennedy School's Center for Public Leadership. Through this fellowship, she received a full scholarship to complete an Ed.M. in Education Policy and Analysis at Harvard's Graduate School of Education. Now overseeing ARCK Boston's Creative Pathways Program, she’s thrilled to support creativity, purpose and confidence in youth that grow their social entrepreneurship skills for positive social impact.
