The Marin School faculty and staff

Some found their passion for teaching early on. Others discovered it after successful careers in other walks of life. Collectively, they bring to the classroom a breadth of academic and real-world experience that makes for an effective and creative learning environment.


Our teachers passionately believe in each student's unique potential and have the talent, tools, enthusiasm and skill to meet the needs of multiple learning styles.
