As a professional Mandarin instructor with almost two decades worth of teaching experience in American schools, I came to recognize how language-learning in a school setting is only one step in the long journey of acquiring a foreign language. I felt a need and urge to bring my profession beyond school, and I believe professional teaching should be accessible to anyone at any point in their life. It is with this belief that I founded MAD Mandarin LLC in 2018 with the goal to incorporate the latest teaching methods with my own innovative approach of Mindful-Active-Dynamic to positively achieve the best language-learning results.
