Our Team


Our teachers are a diverse group who come from all over the world including Chile, Peru, China, Colombia, France, Japan, India, Germany, Puerto Rico and Taiwan. Many have degrees in language and education and years of experience in teaching. Many are parents themselves and experience personally the joys — and challenges — of raising bilingual children. They all have a passion for sharing language and culture with children and their families.
