Leadership Team


Cathy Makropoulos



It is a pleasure to serve as the Director of Montclare and a privilege to be part of such a warm and welcoming community. My door is open to our families and staff and I work closely with Montclare’s leadership team and faculty throughout the year to ensure the success of our students.

Over the past 34 years, I have been an educator of preschool and elementary school students and before joining Montclare, I served as Principal at ACS Athens Elementary School, an American school in Greece.  I am a certified International School Administrator with a Bachelor of Arts degree from LaVerne University and a Master’s Degree in Educational Leadership from Lehigh University.  I enjoyed serving as a member on the committee of Institution-Wide-Accreditation of the Middle States Association (MSA).  Additionally, I was selected to be a member of the European Council of International Schools (ECIS) Early Childhood in 2010 and has remained an active member of this committee.

Being the Director of Montclare Children’s School allows me to continue pursuing my passion for excellence in education for young children!


Sasha Wilson

Associate Director


I am so happy to be entering my fourth year of working at Montclare with these dedicated, nurturing teachers and wonderful children!

Before joining Montclare’s educational leadership team, I spent twenty years at Good Shepherd Early Childhood Center in Irvington, NY, the first ten years as a classroom teacher and, the last ten as the Director. I have participated in such organizations as the Westchester and the National Association for the Education of Young Children and the Westchester’s Directors Association. With my Master’s Degree in Education from Columbia’s Teachers College, I engaged in further studies in Educational Leadership at Manhattanville College. I am very familiar with the Committee on Preschool Special Education and have consulted with them where appropriate.  In addition to my work at Montclare, I am currently an adjunct professor at Hunter College in their Curriculum and Teaching Department.


Jenny Bruce

Head of Enrollment and Communications


15 years ago, I joined Montclare’s administrative team when my oldest son was enrolled as a young 2s.  My second son also attended Montclare several years later. Both have since moved on to their big-kid school (The Lycée Français de NY) and yet, here I remain. Initiating my children’s academic journey at Montclare was one of the greatest gifts I could have offered them.

I am a native New Yorker with a background as a singer-songwriter, blogger, web designer, and photographer. My passion for digital communications and technology led me to enroll at Teachers College, Columbia University where I am currently pursuing an MS in Communication Technology.  I feel very fortunate to be able to work in such an engaging, creative environment with a brilliant leadership team and teaching staff. The icing on the cake is getting to interact with the most creative people on earth; young children! It’s a joy to experience their excitement for learning, playing, and everything!


Mimi Dupuis

Director of Exmissions


When I came to Montclare in 2007, I knew I found a home. I was drawn to the spirit of community and impressed by the commitment to provide the best possible learning foundation for all students. After six years as a head teacher in the Panda Room, I took on my current role in Exmissions.

I began my teaching career in a parochial school on the Lower East Side, and then spent seven years teaching at a private school on the Upper East Side. With a focus on literacy, I became certified in Elementary Ed at St. Peter’s University. In Jersey City, I worked with learning-disabled children in under-served communities. My experience led me to children with communication disorders, especially those on the autistic spectrum, teaching at Learning Spring Elementary and The Rebecca School.

As a head teacher, I was privileged to team with a host of talented educators and related-service providers. At that time I also did private work and collaborated with psychologists to help children with attentional issues and anxiety disorders meet success in the classroom. After a decade of special needs work, I returned for my Masters in Early Childhood at Hunter College.

It is now my privilege to help Montclare families find the right fit for their children as they pursue their educational life in the ongoing schools.


Billie Castiglia

Director of Operations


I joined Montclare in 2000, when its doors first opened.  Actually, before the doors opened! My most vivid memory of those early days is of sitting in the basement, putting address labels (old-school) on hundreds and hundreds of postcards announcing the opening of our school.  We held an open-house on the 2nd floor when it was just a big open space.  Before the construction of all the beautiful classrooms you see today, this 2nd floor could have been a roller-skating rink.

After raising my two sons and prior to joining the Montclare team I worked for many years in HR. Now, my day begins by greeting smiling faces at the door and hearing a chorus of “good mornings. Sometimes, on a really good day, I hear “good morning Billie!”  Then the real work begins. As the Director of Operations, it is my job to ensure that the school runs smoothly on a daily basis.  Feel free to call me a “smooth operator.”

I consider myself to be extremely fortunate to have a job that I love and I am deeply proud to be a part of the Upper West Side, Montclare Community we have built together over the years.
