Yo San Faculty

These extraordinary teachers and practitioners have chosen Yo San—and Yo San has chosen them—because they have a talent and a passion for teaching TCM students, combined with a sophisticated command of their disciplines. Several instructors studied, taught and practiced at some of China’s top TCM Universities; some come from distinguished families of Chinese practitioners; and others trained at American TCM and Western Medical Schools.
