David’s herbal studies class is THE most valuable educational experience I have had in my lifetime. The knowledge I have gained from this class has inspired me to continue to pursue my goal of vibrant good health into the wiser years, and to be a source of information to help others who come to me for advice to do the same. I will be a student of herbal studies and related topics for the rest of my life. Thank you, David, for this gift of knowledge of the gifts and medicines from the earth.
