Teachers and Staff

Julie Liddle, Program Director
Julie brings twenty-five years of experience working with children to her role as Program Director at ERS. She worked as an art therapist in special education for almost a decade, and then specialized in early childhood art. For the next 16 years, Julie focused on creating and facilitating a parent/child art program and curriculum for toddlers and preschoolers, which she delivered in various preschool settings. This is what brought Julie to ERS at its inception, to serve as the school’s Atelierista (Art Director). She held this position for five years before taking on the broader role of Program Director. Julie is energized by the creativity of young children. She enjoys using techniques and materials that inspire children’s innate creativity as a means for creating connections, building relationships, and educating parents and teachers. Julie received a Master’s degree in Art Therapy from George Washington University and her Bachelor’s degree in Psychology from Cornell University. She lives with her husband and two teenage sons, and enjoys year-round campfires and cookouts in their backyard fire-ring, and harvesting and cooking the fruits of her husband’s vegetable gardening obsession. Like her grandmother, Julie swears by the healing power of fresh air, and she finds rejuvenation in daily walks with her only girl, a beagle-mix named Chessie.

Toniann Iovine, Art Specialist
Toniann earned a Master’s degree in Art & Design Education from Pratt Institute and has many years of experience working in progressive education. After starting her career at Friends Seminary and Beginning With Children Charter School in NYC, she took a break from teaching to continue her work as an artist. She returned to education with an opportunity to apply her art and education background overseas. She designed and implemented curricula for children in Sri Lankan communities impacted by the tsunami during the civil war. The community rebuilding was centered around the children and their place of learning. As part of her work in Sri Lanka she ran a gallery that exhibited local artists and provided community art instruction to participants. Toniann returned to NYC and began the juggling act of family and work. At Tompkins Hall, the Columbia University childcare center, she supported play based instruction with topics of interest. As a teacher Toniann feels her role is to be both student and facilitator; she is always listening and learning. She believes it is vital to remain present in the experience and immerse children in experiential learning on subjects relevant to them. She enjoys time with her family and is happy to call Great Falls home.
