I came into David’s program as an eager beginner thinking that I knew something about herbalism. Two years later I realize that there is a much deeper complexity to herbal medicine that I ever imagined. I feel very fortunate to have had David and his ensemble provide me with such a comprehensive foundation that weaves together the extraordinary diversity of fibers, textures, and colors of the herbal world into this one delightfully unique program. It has been a privilege opening my eyes to these perspectives. I have learned and gained beyond my expectations and feel fully confident recommending this program no matter where you are along your herbal journey.
