Help us welcome our new Chief Operating Officer

November 29, 2017

Today we’re thrilled to announce that Sarah Geisenheimer has joined 100Kin10 as our Chief Operating Officer. In this role, we were seeking a seasoned hand to design, implement, innovate and continuously improve efficient and effective operating structures and systems for 100Kin10, and to help translate our long-term strategic goals into reality. Sarah’s leadership will strengthen 100Kin10’s ability to support the work of our partners – helping them to achieve progress in training and retaining excellent STEM teachers as well as addressing the systemic grand challenges facing STEM education: the system-level obstacles that make getting and keeping excellent STEM teachers for all classrooms so difficult.

Sarah previously served as Executive Director of The Fund for Public Schools, where she fulfilled the Chancellor’s priorities for private funding. As Executive Director, Sarah focused the Fund on the strategic use of private funding to test new approaches, track impact and learn with the potential to sustain the work through the NYC DOE which serves 1.1M students. At the Fund, Sarah built a talented team, efficient and effective operating systems and strong relationships with a range of funders and NYC DOE partners. Sarah’s experience in the philanthropy and education sectors, coupled with her expertise in operational systems, strategic planning, and fiscal and team management will make her an invaluable resource in the next phase of 100Kin10 as we move towards addressing the grand challenges.

Sarah is looking forward to meeting and working with 100Kin10’s full staff, as well as working closely alongside our partners to understand how 100Kin10 can best support their work – and how together we can realize our shared goals and work toward systemic change.


As Chief Operating Officer, Sarah leads 100Kin10’s efforts to create and hone efficient systems, both internally and for the organization’s partners. Sarah’s career has focused on devising strategies to optimize organizational performance—from financial health to workplace culture. Sarah previously served as an Associate Director at The Rockefeller Foundation, a Senior Advisor to the Chancellor’s Office of the New York City Department of Education, and most recently as the Executive Director of The Fund for Public Schools.

Sarah holds a Master of Arts from the Teacher’s College at Columbia University, and a Bachelor of Arts in Politics from New York University.
