Heather Ruggiero is the Office Administrator/Assistant to the Directors at Keystone Adventure School and Farm. When Heather saw the “Keystone Adventure School & Farm” sign by the road, she wondered, “what is an adventure school?” Upon learning of Keystone’s whole-child educational philosophy, as well as the outdoorsy nature of the program, she believed that it was gold.

Back to the Farm, one year after the sign, Heather is excited to begin working on the Keystone team. Her three-year old daughter is a Keystone kid this year, too!

Heather Ruggiero has a Master of Arts in Elementary Education and a Bachelor of Science in Business Management. She brings a breadth of experience in business such as coordinating contracts at the Kennedy Space Center in Florida, banking, writing, and managing a government contracting business.

In her spare time, Heather likes her nose in a book and her hands on a warm cup of Celestial Seasonings, Bengal Spice tea. Heather’s greatest joys come from the precious moments spent with her husband Frank, their daughter Lore, and the house fluffball- a Shiba Inu named Inari.

Kelly is at her happiest when she is in the messy middle of her kiddos’ unfolding childhood experiences and growth. She is looking forward to the learning and the working together – as Mr. Fred Rogers once said, “But for children, play is serious learning. Play is really the work of early childhood.”

Natalie considers it a true joy to spend her days with young children and “letting children be little.” Her child-centered curriculum is inquiry-based and rich in meaningful, hands-on experiences. Natalie is passionate and committed to helping students become independent thinkers, to believe in themselves as unique individuals, and learn to honor and respect the differences that help shape the identities of our world. Natalie builds a strong classroom community in which taking risks and making mistakes is expected and valued.
