I have been interested in children’s development for as long as I can remember. Child development holds so many fascinating questions: How do children gain a sense of self? How do they incorporate their early experiences and come to understand how the world works? How can we most effectively support young children and their families as they negotiate our increasingly fast-paced world? How can we best protect children’s play, and advocate respect for childhood and for young children’s well being? These and many other questions drew me to pursue a degree in developmental psychology and then to AHNS, where I feel fortunate to have a position that captures such a perfect blend of my interests.

In many ways, I grew up at AHNS, as my mother, Jean Potter, was the director for thirty-six years. We have always shared a deep interest and delight in young children, and in understanding their development. I have very fond childhood memories of attending AHNS as a preschooler, and of working here in a variety of roles throughout the years.

Prior to joining AHNS, I worked for five years in the pediatric department at Boston City Hospital (now Boston Medical Center), where I was a research assistant and project manager on several large research studies of infants and their development through the preschool years. I was fortunate to receive excellent training in observing and documenting children’s development. Working with infants in the NICU and with the multi-disciplinary teams of clinicians caring for them was a fascinating experience that deepened my interest in child development.

A move to New York City created the opportunity to work at Cornell Medical Center on the New York City Children's Health Project, working with homeless children and mothers, and documenting the impact of homelessness on children and families living in welfare hotels and shelters. In addition, I worked at the Stone Center for Developmental Services and Studies at Wellesley College where I worked on a research and outreach project conducting qualitative research with women in prison in Massachusetts. Working with women and children in such traumatic and demanding settings were powerful experiences that shaped my understanding of how stress, separation, and poverty impacts families.

I have been active on the Community Partnerships for Children Council, as member and chairperson, and have served on the board of directors of Arlington Family Connection and Warmlines Parent Resource Center. I currently serve on the board of the Arlington Health and Human Services Foundation, and am a commissioner on the Arlington Historic Districts Commission.

I’m passionate about my work at AHNS, where I have overall responsibility for the school, manage the administrative and teaching staff, and collaborate with the staff to ensure that that the mission, philosophy and goals of the programs we offer are carried out in the daily life of the school. I also truly enjoy working with families and assisting them with the challenges of raising young children and of understanding developmental changes and issues. I appreciate the opportunities I have at AHNS to observe children at play, listen to parents, and develop strategies for addressing challenging behavior, transitions, or special needs.

I live in Arlington with my husband and our four children, each of whom is a source of endless wonder and inspiration to me. They have all attended AHNS and my daughter Isabella is currently an AHNS preschooler.

My passion as an early childhood educator has always been to create a learning environment that allows a child the freedom to explore their interests and to build their self-confidence. At AHNS, where I have taught for fifteen years, I have been able to nurture my passion to allow children to grow and learn through their own play experiences and also by giving them many opportunities to explore the world around them. In my role as program coordinator, I oversee the eight preschool and pre-k classrooms, including supervising and guiding the teaching staff, overseeing the implementation of the curriculum, and designing the classroom environments in collaboration with the teachers.

A major inspiration for my work with young children has been my brother John, who is deaf. It was often a struggle for him during his early childhood years to cope with the world with no sound. Learning experiences were different for him. As a young child I learned how to adapt my imaginative play world so John and I could play together. What I learned through the years with my brother is that the universal sign for happiness is a smile and that using the senses you have brings things to life in different ways. My play and social experiences with my brother have led me to value teaching and encouraging a child to learn through their senses. We know from research that children who explore and discover through play, using their senses of smell, touch, taste and sound experience a greater understanding of the world around them.

I attended Framingham State College, where I studied Clothing and Textile Design. I also studied early childhood education at Wheelock College and Middlesex Community College. Before I became a teacher, my two children attended AHNS. While my children were here, I was the Parent Volunteer Coordinator, and planned many community events for the school. I live in Arlington with my husband Nick. Our two daughters are currently in college.

My interest and delight in young children began with the birth of my only sibling when I was ten years old. I began working summers as an assistant teacher with young children in a school setting when I was fifteen, and, after college, worked as a kindergarten/primary teacher. In 1969, after enrolling my youngest child, Margaret, in AHNS, I joined the staff as a teacher, and, later, became director of the program until my retirement in 2005. I began teaching early childhood courses as an adjunct faculty member at Middlesex Community College (1984) and supervised student teachers from Middlesex and Lesley University until my retirement. I have greatly enjoyed sharing my love of young children and my ideas of what kind of school programs support the optimum growth and development of young children in these settings.

I am a long term resident of Arlington where my four children were raised. I am a member of the National Association for the Education of Young Children and am active in the Boston affiliate, serving on the committee to plan the annual Director’s Conference. I am very proud to have been a founding member of the Arlington Early Childhood Association, a group of directors of early childhood programs that has met monthly for the past 26 years. I have been active in the Arlington community with organizations such as the League of Women of Voters of Arlington (past President), Library, and Arlington Historical Society. Middlesex Canal Association, and the Community Partnerships Council since inception and as a former treasurer.

AHNS has long supported the presence of children with mild to moderate special needs in our program, dating from before there was state and federal legislation to support this concept. Our program has been greatly enriched by these children and the specialists who have provided services for them in our school through the years.

It has been a pleasure and a source of great pride to watch AHNS grow and expand under the guidance and leadership of my daughter, Margaret (the preschooler who I enrolled here in 1969!). I continue to enjoy being a part of AHNS through consulting on children with special needs, designing developmentally appropriate curriculum, and through working in the office three afternoons a week.

My career in Early Childhood Education began at a young age as I discovered my love of working with children while having steady babysitting jobs. In 1995 I attended San Diego State University and earned a bachelor’s degree in Child and Family Development. While at SDSU, I was fortunate to meet some of the great educators and theorists in the field such as Magda Gerber, Bev Bos, and Urie Bronfenbrenner, who have shaped my way of thinking and approach with young children. These experiences along with my course work laid the foundation for my philosophy of education for infants and toddlers.

After graduating from San Diego State University in 1998, I decided to try living on the east coast and moved to Boston. Since then I have been teaching in both preschool and infant and toddler classrooms. I find watching children’s development unfold and seeing their approaches to interacting with the world to be endlessly fascinating. While earning my Master’s degree at Wheelock College in Infant and Toddler Development and Early Intervention, I gained a deep understanding of child development as well as how a child’s relationships and environment can impact their growth. One of my greatest passions is documenting how children approach and interact with the world. I find young children’s ability to explore materials in a way that gets their questions answered something to be respected.

It has been an honor to become part of so many children and families lives over the course of my 14 years working in the classroom. These relationships have been one of the gifts I treasure the most in doing this important work. I’m glad to be able to share my passion for working with young children, families, and teachers as I continue my work at Arlington Heights Nursery School as the Infant-Toddler Program Co-Coordinator.

Along with my Co-Coordinator, Lise White, I will be overseeing the five Infant-Toddler classrooms, including supervising and guiding the teaching staff, overseeing the implementation of the curriculum, and designing the classroom environments in collaboration with the teachers.

I first became fascinated by infants and toddlers while volunteering at Seattle Children’s Hospital holding and comforting ill and premature babies. In 1999 my life’s path lead me here to Boston, where I began working as the assistant teacher in an infant room. During the next five years, I worked my way up from assistant teacher to team coordinator at Peabody Terrace Children’s Center, while earning my master’s degree in child development at Wheelock College. The more I learned, the more questions I had about development and the way it unfolds according to a predictable progression, yet so uniquely for each child. Much of my graduate work focused on exploring the questions that grew out of my observations in the classroom: Do infants form secure attachments to multiple caregivers? How do children learn two languages simultaneously? By what process do infants become capable of representational thought? How do we support babies who have difficulty adapting to the group care environment? This idea of teacher as researcher is central to my philosophy of caring for infants and toddlers in groups, and inspires me to observe closely, think deeply, and wonder freely as I work with young children.

At its core, caring for infants and toddlers is about forming trusting relationships with babies and families. I am extremely lucky to have loved and been loved by so many babies over the years. In 2004, my husband Dan and I welcomed our own babies into the world, and now have an energetic household of twin four-year-olds and a 2-year-old, who burn off some of that energy here at AHNS. We love to hike at Great Meadows in the spring, go to the beach in the summer, pick apples in the fall, and ski and skate in the winter.

At AHNS, I oversee the five Infant-Toddler classrooms, including supervising and guiding the teaching staff, overseeing the implementation of the curriculum, and designing the classroom environments in collaboration with the teachers.
