Our Faculty
In addition to being experienced and passionate teachers, Marin Horizon teachers are learners themselves. While many of the faculty have been in the school for more than 20 years, they keep abreast of and adapt to the most advanced teaching and learning methodologies with professional development.
The faculty delivers a rigorous and challenging academic program, where each grade’s curriculum has been thoughtfully crafted, and purposefully connected to the next grade for a seamless continuity of learning. Using the innovative Universal Design for Learning models, the teachers work together across disciplines, to foster students’ curiosity and learning needs.
