Meet Our Teachers

Our teachers are the heart of Spring River, and have been chosen by the Spring River Committee because they are proven educators with a devotion to an arts-infused, whole-child curriculum that honors the natural world and the developmental phases of childhood.  Some of our teachers are also homeschooling their own children, or have done so in the past, and can prove to be a helpful resource for families new to homeschooling. Some of our teachers have backgrounds in public school education and have chosen a new path with a focus on Waldorf Education and/or certification. Others have created their own stand alone course offerings which they have molded to fit into the Enrichment Class model of Spring River.
