Pythagoras Greek School (PGS/PSGS)

Greek School, a must for every Greek Orthodox parish, is the vehicle that creates the Greek identity in the minds and the souls of our children and is important for the existence of the Greek Orthodox Church. The purpose of the Pythagoras Greek Schools is to promote Greek language, the Hellenic culture and our Greek Orthodox Heritage. Our goal is to create a feeling of love for the Greek language and most importantly, to generate a sense of pride for our religion and heritage.

Students are taught reading, writing and speaking Greek as well as religion, mythology, history and traditional Greek Dances. Each grade level has its own teacher to ensure that all students realize exceptional progress throughout the school year. Our teachers have many years of teaching experience in Greek parochial schools and are highly qualified to teach Greek as a second language.

Pythagoras Greek Schools offers the following  programs

PGS - Monday & Wednesday classes  (4:30 - 6:30pm)

PSGS - Saturday classes  (9:00am - 12:30pm)

Ellinomatheia Preparatory Course for the Ellinomatheia Greek state exam on Wednesdays 4:30-6:30pm.
