She also got her Masters in Early Childhood Education and acquired a Utah teaching license. Here in Oregon she holds an Oregon teaching license and continues to develop her knowledge of social-emotional learning, empathy, outdoor learning, mindfulness and whole-child development through continuing education. She has worked with children from preschool through third grade in various capacities for the last fifteen years and is thrilled to take the knowledge she has on early childhood education outside.

Amy Nelson - Outdoor Science Educator

Amy (Horn) Nelson

Program Director

Amy grew up playing and exploring the woods of northeast Texas. Those long days spent building forts, fishing, and climbing trees fostered a deep love of the natural world. A trained ecologist, Amy earned a B.S. in Agroecology and Environmental Quality from the University Hawaii at Hilo. Much of her life has been spent working in and exploring the outdoors. She was the founder, director, and facilitator of the Yamhill County Free Forest School. Amy believes all children are inherently curious, innately connected to the natural world, and benefit from unstructured outdoor play.

Claudia Gabriela Gonzalez Davila

Early Childhood Educator

As an Early Childhood educator, Claudia holds a degree in Education from La Salle University in Mexico City. Born and raised in different cities of Mexico, she’s been surrounded by the mountains in northern Mexico, lived an amazing life by the Caribbean Sea, and studied in the vibrant Mexico City. She has always been deeply connected to nature and its wonders, every place she’s lived has taught her about different lifestyles, communities and families.

She firmly believes that through the power of play, children not only learn but also develop essential life skills. As an outdoor school facilitator, she’s been able to witness this transformative process firsthand.

Being bilingual and bicultural, allows her to bring a rich perspective to her work. Currently she’s dedicated to the Spanish curriculum for the Nature School program in McMinnville, where she continues to explore and deepen her connections to her own culture and her role as a playworker and bilingual facilitator. She feels passionate about helping others learn Spanish without pressure and in a natural way.

Claudia hopes to continue to grow, challenging herself, and learning from nature and learning with children around her.

She likes to remember that each child has unique individual qualities and that we can support and help guide them to find their own way to learn and thrive in this world.
