HuebnerGreg Huebner, Bilingual Psychologist

My name is Greg Huebner and I am the bilingual school psychologist at Powell.  I recently received my M.S. Eds from CUNY-Brooklyn, and completed my internship in Fairfax County, Va.  I’m excited to be working at the best elementary school in Washington D.C.  My professional interests include teaching social emotional learning to students and parents, as well as bringing a strong focus on Response to Intervention to the classroom.  During my graduate program I worked for a wonderful non-profit called, Move This World, which focuses on creating self-awareness and actualization in children through movement based activities and gave me a lot of experience working in the classroom.
I’m married and my wife and I have a rescue dog and cat who both love to be outdoors and they’ve kind of learned to like each other. (Imagine the dog and cat from Tom and Jerry.)  Personally, I love travelling, hiking, bicycling, reading, and playing the guitar.   I believe that the school psychologist can have an extremely positive impact on the overall quality of a school and the key aspects to creating that impact are relationships with teachers and staff, relationships with families, and relationships with the community.
