Raymond Burns

Ray also is the creator behind a successful online business and has grown both a Youtube channel and Facebook Group dedicated to supporting physics teachers.


Ray first decided to become an educator after taking a gap year following high school. During that time, he traveled around the country doing service projects. It was then that he realized he had always loved learning but had disliked traditional schooling. He then decided to become an educator who would encourage students to discover themselves, find their unique passions, and build meaningful relationships.
