About Us: Board of Trustees

Board of Trustees - Officers
Nadine Durham, Chair	Nadine Durham joined the Board of Trustees in July 2019. She is currently the Director of Revenue Management IT services at Amerisource Bergen Corporation. Nadine and her husband Gerard have been a part of the French International School community since 2008 and have two daughters who have attended the school from PK3 - 8th grade. Through business and personal travel around the world she and her husband have seen the importance and benefits of being exposed to other languages and cultures. "With an incredible staff and community, the school has afforded our children the opportunity to receive their education in a diverse, multicultural environment. This unique environment has prepared them to be great thinkers with a global understanding, fluent in three languages". Nadine has been a member of various committees through her career and in her community and looks forward to serving on the EFIP Board of Trustees.
Andrew A. Chirls, Vice Chair	Andrew A. Chirls joined the Board of Trustees in 2014, and is now one of its Vice Chairs. An attorney with Fineman Krekstein & Harris, P.C., in Philadelphia, Andrew is thrilled by his eldest daughter’s experience in kindergarten and first grade—the diligent approach to bilingual teaching, and the joy of discovery and creation that is part of every day for this child at her school. He believes that children benefit if they are citizens of the world, as they will understand and empathize with others and know how big their own experiences can be. His law practice and experience as a leader of the Philadelphia bar have brought him closer to the French community, as have his study of French and his travels in France. He is thrilled that he and his husband, Jim, are part of the community of families associated with the French International School, and he is delighted to be advancing the cause of an interesting and valuable education for the children of these families. Andrew’s twin daughters are starting PK3 in 2020.
Cornel Fuerer, Vice Chair	Cornel Fuerer has been a member of the Board of Trustees since July 2020. He and his wife Bokkyeong have three children who were previously enrolled at the French International School. Their experiences living on three continents have given them a greater appreciation and understanding of other cultures. Their international travels have reinforced their belief of the importance of speaking and understanding several languages. Cornel serves as a Senior Vice President and General Counsel of Corteva, a company dedicated to agriculture. He has earned his law degree from the University of Geneva School of Law and holds a master’s degree from the New York University School of Law. He was born in Switzerland.
Sylvie Satre, Treasurer	Sylvie Satre joined the Board of Trustees in July 2018, returning to the Board after a previous six-year term as Treasurer from 2001 to 2006. Sylvie graduated from l’École des Sciences Politiques de Paris and is now Senior Director, Regional Finance for Covanta, a company providing renewable and clean energy from waste. She also currently holds the position of Treasurer on the Board of the French Benevolent Society. Upon their arrival in Philadelphia in 1999, Sylvie and her husband Gérard decided to send their two daughters to the French International School (EFIP) to help them transition as smoothly as possible to a new country and environment. 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. Sylvie believes that, throughout their combined 21 years at the school, EFIP taught her daughters not only academic excellence through rigorous coursework and high expectations but also the acceptance of diversity as a driving force capable of developing open-mindedness and a more positive world view. 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. Through her new position as Treasurer for the 2020-2021 school year, Sylvie is thrilled to be able to take part in shaping the school’s future.
