Ashton is a Board Certified and Licensed Behavior Analyst with over ten years of experience supporting individuals to meet their optimal potential through the application of behavior science.  She’s always been drawn to service, and after completing a year with AmeriCorps in her hometown, she moved from Pennsylvania to Massachusetts to pursue her graduate degree in Education and Applied Behavior Analysis.  During her graduate coursework she grew her passion of working with children, gaining professional experience in both private and public educational settings as well as in community and home settings. Valuing diversity in experience, Ashton took an opportunity with the Cleveland Clinic Children’s Hospital after receiving her Master’s degree, to work with pre-school aged children with intensive needs.  In wanting to return to an educational setting, she took a job as an administrator and Behavior Specialist for The Auburn School in Virginia, where she jumped into a leadership role through supporting the academic, social-emotional and behavioral programming for students, staff and the school.  


Ashton is thrilled to join The Madrone School, and can’t imagine a better setting to continue pursuing her passion for supporting unique learners, their families and her colleagues.  She is excited to relocate to Washington State after being a life-long East Coaster.  When Ashton isn’t nerding out about the power of person-centered behavior science, you can find her hiking in the woods, experimenting in the kitchen, jamming out to the sounds of her record player, or exploring the shelves of her local library.
