Their Passion Is Contagious

Every one of our enthusiastic teachers brings with them a love of the classroom.  The majority have advanced degrees and certifications, and many actually went back to school because they loved teaching so much.

  • Our Science classes are taught by experts, with advanced degrees in their fields.

  • Our Social Studies department is led by two of the most passionate individuals you'll meet, with degrees and real-world experience specific to the fields they teach

  • Our Lower School teachers bring world-wise experiences and advanced degrees to bring a broad-based education to the table, expanding the horizons of our youngest students.
