Ever since her first observation in a Montessori environment fifteen years ago, Babbs has been passionate about carrying out Montessori’s vision of fostering caring communities of joyful learners. Informed by her AMI training, studies in yoga, meditation, and Taoist practices, has also become invested in fostering a more holistic approach to education, one that meets each child where they’re at in order to nurture a future generation of global citizens who are as empathetic and socially aware as they are confident leaders.


Babbs’ experience over the last several years working with children as Classroom Guide, Interventionist, as well as the greater community as Presenter and Coach has shown her the powerful part each adult plays in shaping a child’s experience.

Mary Hanyok has a lifelong love of learning. She just loves school. She loves school so much that she can’t get away from it. In one form or another, Mary’s always been in school- as a student, as a teacher, or as a parent volunteer. After earning a Bachelor’s in Anthropology, she stumbled into her first job as an assistant in a local Montessori school. While there, she became enthralled with the work the children did. It seemed amazing that such challenging concepts were always
presented in such a straightforward and concrete way. What followed next could only be described as a flurry of graduate school. First, Mary attended St. John’s College in Annapolis, earning a Master’s in Liberal Arts. It was here she rediscovered her love of philosophy and became convinced that Euclid most certainly was a genius (until she came across non-Euclidean geometry and had to rethink things). After that, Mary attended the Washington Montessori Institute, earning her AMI Elementary Diploma and a Master’s in Education from Loyola. Since then, she’s enjoyed working in both Upper Elementary and Adolescent classrooms, and is constantly reaffirming her belief that Maria Montessori was the smartest person ever. Recently, Mary has been working on her most challenging position yet, Montessori mother to 3 young boys. In her “free” time, Mary enjoys anything that can be done outside or in a kitchen, or both.

Enyah Perez

Hello! My name is Enyah Perez and I’m so happy for the opportunity to introduce myself to the community and in a returning capacity as I am also proudly a MAMS alum! And now, after spending most of my life in education-I feel more poised and honored to return along side the amazing staff here at Mater Amoris. Studying and learning from the Montessori method has offered so much in my understanding of the world - how it works in terms of the physical and how it is shaped, designed and built. As a child, it gave me the internal structure for
understanding my passions and interests and has laid a foundation for which I connect with the world and find inner peace. 

A little about me - my primary interests and hobbies surround positivity, music, art, science, nature and how we all can relate to each other through these wonderful
things. My education after Mater Amoris led me to the Field School in Washington D.C. and then the University Of Hartford where I graduated from the Hartt School of
music with a BFA in Music Production and Technology. After college I spent some time working as a DJ/musician and teacher in Oregon where I spent part time as a
wedding DJ, 10 years as a High School special needs assistant teacher, a mac and cheese chef and a basketball coach with Special Olympics Oregon. All this said, I can’t wait for a chance to get to know you all and work with the
students here at Mater Amoris!
