Who We Are: Leadership

PEL school heads and teacher mentors come from a variety of educational backgrounds and a wide range of teaching experience. Some of them have gone to traditional schools of education and many of us have earned degrees in particular disciplines. However, in true progressive fashion, all of them actually learned to teach and grew as teachers "by doing".

Most importantly, what all of these school leaders and mentors have in common is a commitment to sharing their experience with young people who wish to become powerful teachers and agents of change in the profession.

Susannah Wolf
Head of School
The Miquon School

Susannah believes the heart of Progressive education is found in the relationships forged through the deep respect teachers have for their students as learning, developing individuals. She came into teaching because she wanted all kids to have the opportunity to love math the way she did as a student at Miquon. She is thrilled to be back at Miquon where she still loves playing in the creek and getting dirty.
