Our Teachers


Peachtown Staff


Peachtown encourages cooperative learning for its students and cooperative teaching for its teachers and administrator.  The teachers and administrator at Peachtown work together.  Each teacher knows every student and has the opportunity to work, eat or play with them everyday.  We have no substitute teachers, just fellow teachers.

The Peachtown staff is comprised of full time, part-time and adjunct teachers.  Staffing is adjusted to accommodate the current student population with the goal of maintaining a 6 to 1 student/teacher ratio.  The Lower Level classroom houses grades pre-K - 3 and the Upper Level classroom houses grades 4 – 8.  Each of these classrooms has a lead teacher and may utilize part-time or full-time teaching assistants as enrollments warrant.

Peachtown teachers are hired based upon their talent for teaching.  New teachers are mentored as they develop their skills in the classroom.  Proven teaching ability and the academic rigor of their educational experience is valued above teacher certification.  Due to the nature of the curriculum, teachers must be researchers and learners.  Teachers may or may not hold state licenses.
