Summer & Care Camps Co-Coordinator

Maria holds a PAMS (Pan-American Montessori Society) Early Childhood Montessori Teaching Credential from the Learning Collaborative, formally Kennesaw State University, Georgia in 2016.


She loves working with children of all ages and began her career as a speech therapist with a Bachelor's Degree from Santa Paula University. She first started working with children when during her college years as a preschool assistant, and in the process of this work was when Maria fell in love with the Montessori methodology. The way that children learn at their own pace and in a practical way and by manipulating each of the materials appealed to what she already knew about how children learn. She observed how the children can acquire knowledge easily and always seem to be inspired to learn more. In addition to supporting their achievement and promoting their independence, it was in that learning environment that she made the decision to pursue Montessori teacher training. Since 2016 she has worked as a guide for children ages 3 to 6 years old in Costa Rica before beginning work here in 2022.

Summer & Care Camps Co-Coordinator

Teresa holds a BA from SUNY Oneonta, in Adolescent Education
with a concentration in Spanish (Grades 7 -12). She has been at Castle Island since June 2021, beginning as a summer Camp Lead Guide, and starting the school year as an Early Childhood Assistant Guide.


Since beginning work at Castle Island, I realized that being
"observant" is an important quality in working with children. Observation is the key to knowing more about the child's abilities and needs. The Montessori learning environment is teaching me that the child has the freedom to decide and express his/her thoughts and opinions; in other words, to become more independent. In Montessori each child develops autonomy and independence, allowing for better self- esteem, a sense of responsibility, and an understanding of limits and respect. I enjoy contributing to children's development and cognitive learning through my work as a guide, caring for the classroom environment, the materials, helping children and encouraging them to explore, complete, and create.
