Open Houses

We welcome you to join us at an Open House. These are designed to help you get to know our school. During these parent-only evening events, you will have an opportunity to ask questions, tour classrooms, speak to WSMS faculty, trustees, and parents, and hear Mimi Basso, our Head of School, discuss the philosophy and mission of West Side Montessori School.

Parents are invited to attend an open house before submitting an application. Reservations are not required. Open house dates will be posted in September.
