Leadership Team

Cathy Makropoulos


I am honored and delighted to be the Director of Montclare and it is a pleasure to be part of such a warm and welcoming community.  My door is open to all parents and I welcome your suggestions on matters concerning your child.  I also encourage you to seek the input of the faculty and myself, as we work together throughout the year for your success of your children.


Before joining Montclare, I was the Principal at ACS Athens Elementary School in Athens, Greece for 23 years! Originally born in Canada, I was raised in New York. I earned my Bachelor’s Degree from LaVerne University.  I am a certified International School Administrator and earned a Master’s Degree in Educational Leadership from Lehigh University.  It has been my privilege to serve as a member of the committee of Institution-Wide-Accreditation of the Middle States Association (MSA).  Additionally, I was also selected to be a member of the European Council of International Schools (ECIS) Early Childhood in 2010 and have since then been 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!


Ashley Warren

Director of Admissions

After spending 10 years in a classroom here at Montclare Children’s School, 9 of those years as a Head Teacher in a 2s classroom, I am thrilled to be Montclare’s  Director of Admissions. Beginning in 2013, Candida Gray, Montclare’s founding Admissions Director, began mentoring me, leaving me prepared and excited to take on this exciting role.


As a mother of a two young children, I know first-hand how it feels to be embarking on choosing the right school for your child. Having an M.S. in Early Childhood Education, and a deep understanding of child development, I truly believe in our mission and philosophy here at Montclare Children’s School and look forward to sharing with you everything our wonderful school has to offer!

Jenny Bruce

Director of Communications

As a professional singer/songwriter, music was my life.  That is, until I had children!  In 2005, I joined the administrative staff of Montclare while my sons were enrolled.  It has been years since they moved on to their big-boy school, The Lycée Français de NY, and yet, here I remain.  Initiating their academic journey at Montclare was one of the greatest gifts I could offer my children.  I owe my parents that same debt as a 12 year veteran of The Chapin School and a Barnard graduate.


My boys genuinely loved coming to Montclare each day and perceived learning to be fun thanks to their extraordinary teams of teachers.  They continue to love school (I pinch myself daily).  Just as my children discovered the joys of learning at Montclare, I have found great joy in working as a part of this vibrant community of administrators, teachers and families.  Although, I never could have guessed how much I would love working in a preschool, now I simply can’t imagine working anywhere else.  And yes, if you hear singing in the hallways, on the Montclare CD and at graduation – that’d be me!

Sasha Wilson

Director of Education – 4s Program

I am so happy to be working at Montclare with such 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 Educational Director. I attended sessions for Directors at the Westchester Child Care Council where I stayed abreast of the issues and requirements affecting young children and interacted with other Directors and I am very familiar with the Committee on Preschool Special Education process and have consulted with them where appropriate.

With my Master’s Degree in Education from Columbia’s Teachers College, I engaged in further studies in Educational Leadership at Manhattanville College. This 8-year tenure followed working for 9 years as a Head Teacher in various programs.


Elizabeth Soqui

Director of Education – 2s & 3s Program

With my Master’s Degree in Early Childhood Education from Hunter College, my teaching career began over ten years ago in a three’s classroom. I enjoyed working in a classroom environment and found it rewarding to support the unique needs of each child. I am the proud mother of two boys, ages thirteen and sixteen, who are both enrolled in public schools in New York City. I remember well their early childhood educational experiences in an educational coop where I was an involved parent. That experience formed an important beginning for their journey of lifelong learning and inspired me to become a teacher.

I am looking forward to working in my new position as Educational Director where I will be able to utilize my earlier career experience in human resources management as well as my teaching experience to support the teachers in our two’s and three’s program!

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 with Alex Angel, Aleyda Chung and Janet Ono, 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.

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.

Daniel Tandet

Danielle Tandet

Associate Director of Admissions

A born-and-raised New Yorker and graduate of Columbia Grammar, I joined my Upper West Side, Montclare family in April 2012 as an assistant teacher. Prior to coming to Montclare, with a degree in Drama from Kenyon College, I worked in various administrative positions in the theater industry. Steeped in the knowledge that “all the world’s a stage,” I entered the classroom ready to put my skills to use in early childhood education!


After two very engaging years of classroom experience, I became the Program Coordinator where, among other things, I managed Afterschool and Summer Camp.  It has been an exciting transition into the Admissions office where it is my pleasure to work with Ashley. We love meeting new families and filling our school with wonderful children!
