David has taught me and expanded my knowledge with this class.  I have not only learned about what the herbs do but also how to put it together in a formula which I have not learned with my other teachers.  Without taking his class I would not be practicing herbal medicine with pets and people today.  I am glad I have found his school to be able to learn from someone with his expertise and knowledge.
