Rebecca Stanton, the chair of Groton’s Modern Language Department, holds a BA from Universite Rene Descartes, and LLM degrees from Universite Pantheon Sorbonne and Boston University. After graduating from BU with a specialty in tax law, she worked for a lawyer in Boston, then turned her energies toward teaching.  She joined Groton’s faculty in 1993. Besides teaching French, Rebecca recently created an Arabic elective for seniors, which she co-taught. In 2009, she was awarded the Breck Award , which recognizes excellence in teaching.

Rebecca  is faculty advisor to the Jewish community, French club, Spanish club, International Community Advising Program, and a judge for the Groton Debate Society. She also works part-time in the Admission Office.

Rebecca and her husband, Gary, have two children, Emilie ’09, who attends Boston University,  and Alexandre, who attends the International School of Boston. When time allows, Rebecca can be found with a good book, a glass of wine, and a map of the next country she plans to visit.

Associate Head of School Andy Anderson arrived at Groton in the spring of 1980 to coach rowing. After returning to the consulting world for six months, he came back to the Circle in January of 1981 to teach English and work in the Admission Office. After ten years in that capacity, he switched to teaching Spanish full time, a move that was possible because he grew up in Latin America and Spain. He has taught Spanish at Groton for the past thirty years.

John Conner, affectionately known throughout the Groton community as "Señor," arrived at Groton School in 1981. A graduate of Amherst College, John received his MA in Spanish Language and Linguistics from the University of Wisconsin a few years after a backpacking adventure throughout Europe, where he fell in love with Spain, its language, people, and culture. John’s textbook series, Breaking the Barrier (Breaking the Spanish Barrier and Breaking the French Barrier) reflects his creativity, tongue-in-cheek fascination with pop culture, and belief that all students can succeed in languages. Breaking the Barrier shines an unapologetic light on the importance of grammar in mastering a foreign language. According to Señor, "When you have a good foundation in grammar, you can go places you've never been before!" He is a frequent speaker at language conferences throughout the world. Breaking the Barrier was the first series showcased on Apple's iTextbook store.

At Groton School, Señor Conner is also dean of faculty; he is the current recipient of the E. Roland Harriman Chair. He also coaches boys varsity tennis, a perennial powerhouse in the ISL; the squad won the league in 2018 with a 15–0 record. Señor Conner has four children, Jamie ’11, Hannah ’14, Alexandra ’16, and Sarah ’19.
