Head of School and Teacher-Leader

Erin is originally from Atlanta, Georgia, where she attended a Montessori school from the age of three to the age of twelve. After receiving a Bachelor’s degree in violin performance from the New England Conservatory, she returned back to her Montessori roots and earned her AMI primary training from the Montessori Institute of Atlanta (now the International Montessori Training Institute.)  She also holds a Master of Education from Loyola University Maryland.  In her free time Erin plays her violin (or viola, guitar, or ukulele, mandolin!) practices and teaches yoga, and spends as much time outdoors as possible--preferably in the Mt. Auburn Cemetery or the White Mountains! 

Casey McClellan


Casey was born and raised outside of Boston. She holds a BA in History and Environmental Studies from Mount Holyoke College and an MA in Museum Education from Tufts University. After graduating from college, she spent five years working with children of all ages as an AmeriCorps tutor, a museum educator, and as a nanny. These experiences made her passionate about providing hands-on learning opportunities for and developing authentic relationships with all children, and she is now thrilled to do both as part of the Montessori and Wildflower families! She is currently pursuing her Elementary level AMI diploma at the Montessori Training Center-Northeast. In her free time, Casey loves to run, sing, read, spend time outside, and go to the theater and museums.

"Now what really makes a teacher is love for the human child; for it is love that transforms the social duty of the educator into the higher consciousness of a mission."
