Claire Kamenski

Born and farm-raised in Milwaukee Wisconsin, Claire graduated from the University of Milwaukee-Wisconsin with a Bachelor of Science in Kinesiology while also competing on the Women’s NCAA Division 1 soccer team. After graduating she went on to earn her Master's of Teaching degree from Northeastern University.

Claire then moved to Oxford, England to teach at the primary and elementary levels as well as work as the lower school Literacy Coordinator. Claire’s passions for nature, music, movement, and living a healthy lifestyle led her to learning as much as she could about the Reggio Emilia approach. While Literacy Coordinator, Claire designed models of emergent and progressive curriculum to be implemented across the lower school grades to encourage school wide child-directed learning and understanding. After moving back to the USA and having her daughter, Ella, born on 11/11/11, Claire taught in a number of places looking to find an educational environment that both inspired her and shared her philosophy of teaching. After what seemed an impossible search, Claire found Henry Frost and fell in love. She is extremely excited to start on a collaborative and enriching journey with the Henry Frost children and community.

Katie Moustakas

Katie began her formal work in education while studying at Boston College where she triple majored in Early Childhood Education, Elementary Education and Human Development. She earned her Bachelors Degree in Education and immediately found her herself teaching in a small nursery school in the suburbs of Massachusetts.  While teaching she continued on at BC earning a Master’s Degree in Special Education.

Katie finished graduate school and moved with her husband to California for him to pursue his graduate studies.  While in California, Katie worked as a lead teacher in a preschool classroom.  She worked with co-teachers to develop well-rounded, child-centered curriculum. In 2002, Katie began teaching kindergarten in an urban elementary school in Northern California. She worked hard to reconcile helping her students meet district and state standards and benchmarks, all the while keeping the work developmentally appropriate. She embraced all the challenges of a large, extremely diverse population and started each day with a smile on her face.  Her love of nature inspired her to partner with her grade level team to design a planting and life cycle unit that not only addressed grade level benchmarks across the curriculum, but included the building gardens beds on the asphalt outside her classroom so her students could have a hands on experience planting, growing and harvesting in their urban environment. 

Katie started a family and returned to Massachusetts with her husband and now two sons and a house full of pets! Katie first discovered Henry Frost Children’s Program when her youngest child was in need of a new preschool. With her children now in elementary and middle school, Katie is thrilled to return to Henry Frost as a substitute teacher and looks forward to continuing to help children learn and grow as members of an amazing community.
