Ms. Liz Vaccaro
Office Manager

Ms. Roxanne Aufieri
Roxanne Aufieri has been part of the Bronxville Montessori School family for many years.  A 1973 graduate of Iona College’s Teacher Education program, Roxanne worked for years as a men’s outerwear buyer traveling throughout Europe and the Far East.  In September 1987, she began her career at the Bronxville Montessori School working in the Toddler Program.  Roxanne soon became an Administrative Assistant to our Executive Director Jean Nelson and in 1995 was named Co-Director of Bronxville Montessori School.


After 34 years of excellence, Ms. Roxanne Aufieri has decided to retire from the Bronxville Montessori School team.  A talented administrator who began as a toddler teacher and later, by applying her extraordinary business skills, served as the assistant director to Ms. Jean Nelson, has left an unfillable spot in the office. She was masterful at meeting the challenges of keeping the school in compliance with all New York State regulations and aiding families and teachers, making everyone feel comfortable as they walked through the doors of the school.  Ms. Roxanne will be missed at her desk, but we are sure she will stop by and bring her wit and laughter through the doors of the school from time-to-time. 

With love and admiration,

Your BMS Family
