Preschool Co-Lead Teacher:




Claudia Roppel

I grew up in Northern Virginia and, as long as I can remember, I have surrounded myself with children. While earning a BA in Communications from George Mason University, I worked at a day care center and also served as a nanny. Being with young children brought me a sense of delight and purpose.

My Montessori journey began in 2000, when I first saw a Montessori classroom in action. I remember thinking how light, focused, and free the children seemed. This prompted me to attend the New England Montessori Teacher Education Center in Cambridge, MA, where I became AMS accredited. I also have a Post Baccalaureate in Early Childhood Education from the Metropolitan State University of Denver.

I have taught at the Primary Level for nine years and have found the experience to be very enriching. Observing children as they discover life’s mysteries and become independent is amazing and has motivated me to uncover each child’s individual learning style and to guide them towards their most relevant pursuit. I believe that a Montessori education gives children and adults an inner compass to help navigate our ever-changing world.

Outside of school, my life revolves around my husband and son. We enjoy skiing, martial arts, kettle bell fitness classes, cooking, traveling, and golf.
