They quickly realized that EFIP was the perfect place for them to continue speaking their native language, become fluent in English as well as grow and evolve in a multicultural environment where everybody had a different background, religion and culture, thanks to the more than 45 different nationalities represented at the school. Their oldest daughter attended EFIP from PK4 to 8th grade and their youngest daughter from PK3 to 8th grade, graduating in 2009 and 2012, respectively.

From their time at EFIP, they have become fluent in three languages and learned to embrace multiculturalism in order to become friends with people from all over the world throughout high school, college and beyond.
