Conference Teacher

Julie Kalpin

Julie Kalpin joined Princeton Montessori School in 2020 as a conference teacher in the Primary Program.

Julie finds joy in the wonders of childhood and the way in which the Montessori philosophy emphasizes and encourages growth during this particular stage of development. She loves to witness the spark ignite in a child when he or she has internalized a new concept after working hard to make those connections. That moment could be when a child comes to learn that empathy and compromise are pillars of social relationships, making the connection that phonetic sounds are used to compose words or the joy that radiates from within when a child first reads.

When not in the classroom, Julie enjoys long walks with her husband and her dog, Rocky. She enjoys reading, traveling, and being active. She is currently developing her ‘green thumb’ through the cultivation of her first home garden.

What Parents Are Saying

Princeton Montessori is the very epitome of the principles of Maria Montessori. The School offers a nurturing, creative, academic, and well-rounded development for each child. As a parent, we cannot offer our daughter a more valuable first gift.

The faculty are, bar none, the absolute best. The teachers are very knowledge both about the Montessori philosophy and the best ways to work with children. I ask for their advice and insight for any issues we’re having at home, quite often. They’re also incredibly warm and nurturing with the children in a way I have not seen at any other school.

I’m struck by how much better the Montessori toddlers are at playing and working peacefully with their peers than toddlers in other nursery school programs. I credit the gifted PMonts teachers, and the Princeton Montessori educational approach, for how confident, happy, and collaborative toddlers in the PMonts program seem.

Landon is so proud of being a third year Primary. He has attended this incredible school since he was one year old. He had absolutely wonderful Toddler teachers and flourished under their care. Now, he is a third year Primary and we know he will be more than ready for Lower Elementary. Thank you to all the Teachers & Staff!

The school runs with one philosophy and so every faculty member and admin personnel share the same vision for the child. This consistency is unique in our area to Princeton Montessori. Combined with the integration of the teacher training program, we can proudly say that the spirit of Dr. Montessori’s principles permeates every aspect of our school. That’s what I value the most about our school!

Education is both a gift and a right. I feel the teachers at PMonts help our children to appreciate the value of their education. Understanding the value involves looking beyond school and appreciating how education is a tool that will allow them to explore challenging goals, to grow as individuals and most importantly, chase their dreams.

I will never cease to be amazed at the capabilities of the young child. In the Montessori environment, the very youngest students show incredible independence and competence. At Princeton Montessori School the teachers truly help the children to “help me do it myself”.

When I think about my personal philosophy on education I can check all the boxes with regards to the education my daughter is receiving at Princeton Montessori. I feel the teachers motivate the students by focusing on appreciating the value of education and the diversities of peoples around the world while stressing and leveraging the power of the uniqueness in each individual student. Ultimately, the role of an educator is to shape a new generation that will create a safer and better world for the future.

Princeton Montessori School is a school that exceeds any expectations imaginable. The school follows each and every child on an individual basis and nourishes each child’s academic, social, and emotional needs. It is a school where teachers appreciate all unique qualities each child brings.

Princeton Montessori School turned out to be the best investment ever. We made some sacrifices in our lifestyle in order to be able to afford sending both children all the way through 8th grade, but now we are proud to note that we have two capable, confident, well-mannered young adults who are a pleasure to be around and who continue to love to work hard in their studies.
