Mara Bernal Grades Faculty Representative
Originally from Colombia, Mara earned her Bachelor’s degree in Education with an emphasis on language teaching. For many years, she taught in her home country, where she developed strong connections with international schools and the IB program. In 2009, she moved to Austin, Texas, and continued her career at an international school with a Spanish immersion program, where she taught for another ten years. During this time, she pursued several trainings in curriculum design, assessment, inquiry-based learning, and mathematics, developing a special passion for teaching elementary math. Afterward, she devoted a few years to raising her son. When it was time to choose a school for him, she was drawn to a Waldorf curriculum. Having already been studying Waldorf pedagogy, she felt deeply inspired by its gentle pace and nurturing rhythm. While her son was in the Bridge class, she fell in love with Great Oak School, where her inspiration to dive deeper into Waldorf education led her to join the faculty. In her spare time, she enjoys reading, gardening, hiking, traveling, and spending time with her family.
