3R Teacher Training was founded in 2013 by classroom teachers with a common passion – helping teachers to meet their challenges and make their classroom lives more rewarding. We have long realized that teachers learn best from other teachers who share their perspectives and understand how valuable their time is and what they need to get from their in-service training. We ignore the pedagogical fads that seem to come in cycles and educational jargon that serves no purpose. We teach nothing that we wouldn’t use in our own classrooms and we take great pride in what we do. Most of all we love working with our favorite people – teachers!
