Welcome to TA’s website!
Whatever brings you here – whether you are a current or prospective student, a panther parent or grandparent, a TA alum, a community supporter, a curious educator, or just an interested Upper Valley neighbor – we hope you find stories, facts, and program information about Thetford Academy that are useful and compelling and that capture the unique and inspired nature of our school.
The Head of School page allows me to share my weekly family letters and other blog posts with the wider world. Topics range from program highlights and parent reminders to student shout-outs and class projects – and so much more. Most importantly, I try to spotlight all of the exciting activity happening on our campus and offer a window into daily life and learning at TA.
Please be in touch with questions, suggestions, and ideas to share!

Carrie Brennan,
Head of School
Thetford Academy
Bio and Experience
Carrie Brennan became the Head of School in 2019. A graduate of Dartmouth College, she was thrilled to return to the Upper Valley where her teaching career launched to lead Vermont’s oldest town academy.
Brennan spent over 25 years in Tucson, Arizona, where she was deeply involved on the founding teams of two new schools – Catalina Foothills High School (1992-2003) and City High School (2003-2019) – as a history and humanities teacher, department chair, professional development leader, and principal.
Brennan’s work as an educator has been widely recognized for its innovation and impact. Career highlights include an exemplary teacher award, a statewide principal award, and the 40-under-40 community leadership award. In 2019, she was named one of Tucson’s “Women of Influence” in the field of education.
At the heart of her practice is the belief that schools are at their best when they are creative and caring learning communities that value human connection and joy, student engagement in meaningful work, community partnerships, and a strong sense of place. Thetford Academy’s positive school culture, student-centered mission, and rich history were a perfect match!
Beyond her day-to-day work leading and learning on the TA campus, Carrie Brennan volunteers as a commissioner for NEASC’s Commission on Independent Schools and serves on the Thetford Historical Society board. In her free time, she is usually outdoors – walking, skiing, skating, swimming, or gardening – embracing each of the New England seasons, or occasionally hunkered down inside with a good book or jigsaw puzzle.
Carrie and her family feel incredibly lucky to live on Thetford Hill, in Thetford Academy’s historic Slafter Hall residence.
