Groton School announces four faculty promotions

Groton School Headmaster Temba Maqubela has announced the promotions of four longtime faculty members. 

Katharine Leggat is Groton’s new assistant head for academics. Formerly the school’s academic dean, Ms. Leggat joined Groton in 1983 and has worn numerous hats over the years: full-time mathematics teacher, dean of students, acting assistant head, dorm head, and coach of varsity field hockey and girls ice hockey. She currently teaches in the Mathematics and Computer Sciences Department, is a girls JV hockey coach, a dorm affiliate in the Lower School, and holds the Thomas S. Williams Chair. Ms. Leggat is married to former longtime math teacher and football and ice hockey coach Jonathan Choate ’60. 

Michael O’Donnell, former dean of students and residential life, will now be assistant head for residential life. Mr. O’Donnell came to Groton in July 2012. In addition to his work in the Deans’ Office, he teaches Latin and U.S. History and has coached girls cross country and crew. 

Former associate dean of students Elizabeth Petroskey has been promoted to dean of students. Ms. Petroskey has been on the Circle for twenty years. She started as a part-time administrative assistant to the deans, became associate dean in 2010, and ran a dorm from 2011–23. In 2023, she was appointed the school’s chief safety officer. 

Director of Student Activities Tim LeRoy will retain that title and also serve as assistant dean of students. Mr. LeRoy joined the Groton faculty in 2013 and has served as director of the Student Activities Committee (SAC), a member of the Mathematics and Computer Science Department, a Lower School boys dorm head, and a coach of girls varsity ice hockey. 

Congratulations to all four for these well-deserved promotions!
