The Crefeld School
The Crefeld School is a private school for students in grades seven through twelve, located in Chestnut Hill, Philadelphia.

History and mission 
The Crefeld School was founded as The Miquon Upper School in 1970 by Arnold Greenberg. Greenberg, a former teacher at The Miquon School (a private progressive elementary school founded in 1932), created the new upper school partly in response to requests from parents and former students from The Miquon School who wanted the opportunity to continue their schooling in the tradition of progressive education. Greenberg was granted permission by The Miquon School's board to include the "Miquon" name in the title of his new school, but the two schools were always entirely independent of each other. To avoid confusion, the upper school eventually changed its name to The Crefeld School.

Crefeld's mission is to produce self-aware, empathetic, lifelong learners.
