Door 21 partners with schools to build leadership capacity for instructional change.  

We empower schools to lead curricular and pedagogical change at all levels of the organization, from deans and division heads to discipline-specific departments and grade level teams. Through individualized coaching and professional development, our clients build the skills, systems and mindsets that create the conditions for transformative faculty growth. Door 21 supports independent and public schools to advance teaching and learning with a commitment to equitable, student-centered and research-informed practice.

“I believe that deep student learning is dependent on deep adult learning, and that schools must see themselves as learning organizations.”

— Indu Chugani Singh, Founder
