The credibility of graduating from the program also has great respect nation wide. I have not walked into a health food store or met an herbalist who wasn't familiar with Michael Tierra. It adds a great deal of credibility when people find out you have studied with him in California.
Of the many herbal training programs I have seen, I consider the East West Herb Course to be one of the best introductions to the world of clinical herbal medicine currently available.
Learn from the best.
