Meet The Staff


Cheryl Calcari
Head of School

Cheryl joined us in 2005 obtaining her Montessori diploma from North American Montessori Center.  In her out of work time Cheryl enjoys the many non- profit organization boards she sits on which help serve the community she lives in.  She spends time reading, swimming and with her family.


Kathy Bryce
Lead Teacher

Ms.  Kathy has been married for 37 yrs.  She has done family child care for years and has been working in child care for most of her adult life.  She has 4 grown children of her own and has also fostered children.  Her children never attended a Montessori school, but later in life, Ms. Kathy realized that she raised her children using Maria's methods.  (It's just a natural way to learn!)  Ms. Kathy has been working at the Petersham Montessori School since 1998. Her love for children and Maria's methods has kept her grounded in her love for learning.  Along with teaching, her other interests are figure skating, hiking, kayaking, camping, any hand crafts such as needle point, knitting, crocheting, and reading.

 Classroom Assistant

A trained Montessori teacher acts as a guide between the child’s readiness and the appropriate lesson. Dr. Montessori recognized the importance of engaging the child’s mind through active interaction with his environment and said that “mental development must be connected to movement and be dependent on it.” Specifically designed Montessori materials enable the child to fix his attention on the lesson by focusing both the hand and the mind simultaneously. This effort at coordinating the brain with movement at the earliest ages is unique to Montessori.
