I enrolled in David’s program because my self-study of herbalism had reached a plateau. I wanted to get to the next level, and over the two years, my knowledge was raised by several levels. The program is comprehensive, covering Western, Chinese, Ayurvedic, Middle Eastern and traditional medicine. This broad approach gives me the confidence to consider herbal protocols in every day life. I have learned so much, and I appreciate the opportunity to study with David. I highly recommend the 2-year program.
