NACSA’s Board of Directors is thrilled to announce that Guerschmide Saint-Ange, NACSA’s Chief Operating Officer, has been appointed as Interim CEO following the departure of Karega Rausch.
Guerschmide’s extensive leadership at NACSA and within several prominent education organizations positions her to shepherd NACSA through this chapter in our 25-year legacy as the guiding light for charter school authorizing. Before joining NACSA, Guerschmide served as a charter school executive director, successfully turning around its academic outcomes and operational effectiveness. She also spent several years as a senior leader in external relations at a large charter management organization before leading a charter authorizing team in New York City.
“We could not be more excited to continue to benefit from Guerschmide’s strong and steady leadership at NACSA as our Interim CEO,” said Ebony Lee, NACSA Board President. “Her work as Chief Operations Officer has ensured day-to-day operational excellence, strengthened organizational processes and infrastructure, and built many elements of organizational strategy. Her vision and experienced leadership will continue to advance NACSA’s mission.”
NACSA’s Board is enlisting an executive search firm to conduct a comprehensive, nationwide search for a new CEO. During that process, Guerschmide’s leadership will equip NACSA with steady guidance, direction, and management, informed by her deep institutional knowledge and expertise in the education sector.
“Throughout my career as an organizational leader, I’ve remained, at heart, an educator first. I joined NACSA nearly 5 years ago because I know every child deserves to have access to a quality school in their neighborhood, and I believe in NACSA’s vital role ensuring that this happens at scale,” said Guerschmide Saint-Ange. “I look forward to leading NACSA and to working with our authorizers to continue to fuel a community-centered school choice movement where quality schools are expected and delivered to all children across the country.”
