Sally Mixsell

About Sally

Sally Mixsell (Mike’-sul) began her career in education as a French and English teacher, eventually moving into administrative roles, including class dean (grade 9), academic dean (gr 7-12), director of curriculum and instruction (gr PK-12), and head of school at an all-girls IB boarding and day school, grades 7-12. Her work in education includes employment at two large PK-12 day schools, a co-ed pre-prep boarding and day school (gr 1-9), and two girls schools (gr 9-12 and 7-12), as well as a graduate program in education.

From 2001-2006 Sally helped design and run the summer intensive masters degree program in education administration, with a focus on private school leadership, at the Klingenstein Center, Teachers College, Columbia University. She was also a founding partner of an educational consulting firm focused on developing leadership capacity at schools. As a consultant she has mentored heads of school and high-level administrators, facilitated strategic planning, run board workshops, developed teams, and helped design programs (e.g., public-private collaboration, faculty evaluation, and faculty professional development). Sally has broad knowledge of school models, thanks to her work at Columbia and as a consultant.  While she continues to support school leadership, she has also been busy with executive searches since joining Educators Collaborative in 2019.
