In 1980, Katherine Watkins and Sylvette Maschino, two teachers from the Lycée Français de New York who wanted to create a truly bilingual school, founded the French-American School of New York.

FASNY started in one room with 17 students attending nursery and pre-kindergarten classes. In this historic location at 111 Larchmont Avenue in Larchmont, New York, FASNY quickly grew to occupy the whole building, which now hosts our preschool and part of the lower school.

To accommodate a growing number of students, a second campus opened on East Boston Post Road in the early 1990s, in the buildings of the former Most Holy Trinity School. In 1995, the second campus moved to 145 New Street, in Mamaroneck, and was home to the preschool and high school, which, in those days, went up to only the 10th grade. In 2017, the high school, now offering classes in grades 9 through 12, relocated to the Most Holy Trinity site, whose buildings were completely renovated and outfitted with the latest academic technology before FASNY moved back.

In 1996, Brigitte Sajous was appointed co-head of the school with Katherine Watkins.

In 2002, Bob Leonhardt was appointed sole head of the school.

A third campus opened in Scarsdale in 2005 to host the preschool. In 2018, the preschool moved back to Larchmont.

In 2007, FASNY added the 11th and 12th grades, offering the S and ES tracks as well as the International Option of the French bacccalaureate. In 2009, FASNY graduated its first high-school class. The baccalaureate success rate was, and has since remained consistently at or near, 100%. The first graduating class also set the tone for stellar college acceptances with, for example, two of its graduates being accepted to Harvard.

In 2011, FASNY acquired the former Ridgeway Country Club in White Plains with the aim of establishing a new state-of-the-art campus surrounded by a nature conservancy. Recently, the school received approval for a revised plan to build a secondary school campus on the Ridgeway site.

In 2012, Joël Peinado was appointed head of school.

In 2015, FASNY was accredited to offer the International Baccalaureate, in addition to the French baccalaureate.

In 2017, FASNY graduated its first IB class with a 100% success rate.

In 2019, Francis Gianni was appointed head of school.
