"I am excited to be a part of the Key School community as a parent and a teacher. I feel lucky to see both sides and it makes me want to be even more involved so that it is a safe haven for our children to grow and for all of us to develop long lasting relationships."

Aude has done research, worked in high tech, taught at the university level and in elementary school, traveled abroad extensively as a child and adult. She believes that no matter where you come from, "learning another language makes you more flexible and adaptable to different situations because you have opened up your mind. It makes you a better listener, a more curious and inquisitive person. You are suddenly exposed to different people, culture, art, food and so on. You are suddenly exposed to countries that are so different but still have so many similarities that children can relate to. They are all so curious and the possibilities to expand their world are endless. It really helps them become better citizens. Learning another language opens up so many doors and it is very inspiring to see children make those discoveries."
