"Since starting my Chadwick tenure 15 years ago, my heart has always been in the Village. As a parent, I watched my two children thrive from kindergarten through sixth grade under the watchful eyes of the experts that are our Village faculty and staff. For me to have the opportunity to lead the Village team, to continue to create a safe, nurturing and joyful space for the youngest members of our community to learn and grow, is an incredible gift. I will continue to bring my admiration for our faculty and staff, my love for learning, my sense of humor and fun, and above all, my deep commitment to making the Village the absolute best it can be for our community. The Chadwick faculty is by far the most committed, talented and dependable group of professionals I have ever been fortunate enough to work alongside. The students are motivated. The families are supportive. Leading this type of community is truly a dream come true."
