Mary McHale
Head of School
"I love that the Montessori philosophy is based on a deep respect for children and for where they are in their development. It honors each individual child and the person he or she is to become. The experience of working in an environment that honors and respects all its constituents – children, parents, and staff, is deeply satisfying. My joy working at MSGH is matched only by the joy I felt watching my daughter experience an authentic Montessori education in a diverse school community."

Mary McHale, MSGH’s 10th Head of School, has been an integral member of the community for the last twenty-five years. As the new Head of School, Mary is eager to embrace the work of providing the most authentic Montessori experience for children and their families. She feels fortunate to have a passionate and dedicated staff with her on this journey.

Before being appointed as Head, Mary was the Director of Admissions for twelve years. Her other responsibilities included mentoring teachers, particularly at the Elementary level, and overseeing programs at both the Elementary and Adolescent Program levels. Overall, she has had sixteen years of Montessori teaching experience, having worked with various age groups in schools both in Europe and the United States. 

She holds a Master of Education from Harvard University with a focus on language and literacy and an undergraduate degree with a concentration in Sociology from University College Cork, now part of the National University of Ireland. She received her Association Montessori Internationale (AMI) teaching diplomas in Dublin, Ireland for both the Primary (3- 6+ years) and Elementary (6-12 years) levels. She also holds a Montessori Special Education Diploma and is qualified as a Reading Specialist.

She lives in West Hartford with her husband, Billy, and daughter, Emma. Emma completed the entire program at MSGH, graduating from the Adolescent Program in 2017.

In her spare time, she enjoys walking, cycling, cooking, reading, and spending time with her family. And though, she’s lived in the United States for almost thirty years, she still likes to keep up with the Irish news.
