David’s Earth Medicine Institute classes are a wonderful balance of intellectual information, practice working with plants, field study and group discussion.   It has been very good to learn this information combined with awareness of the special sacredness and potency of these herbs.  I have a deeper understanding of how to use them for self-healing, and also a wider sense of the cultural context and history. ~ Amara Karuna

The Wildcrafter Certification course has opened my eyes to so many healing plants that I never even knew existed. After learning of their healing properties I now have an appreciation for the “weeds” that are growing in my yard. I am grateful to have learned from David. He shares his vast knowledge freely and clearly. I look forward to learning more. Mahalo David! ~ Holly Engelmann

More of what students have to say:

David’s teaching is rather unusual, in that while presenting an amazing amount of ethnobotanical information of medicinal plants and their uses in our lives; we are ‘cross culturally introduced and restored to relationship with the living world and the true joy of our humanity. This guy knows his stuff and delivers “the goods” ~ Francis Kane


David is a very special teacher. Always in tune and real with his students. His classes are never boring and always interactive, creative, and hands on. The subjects of discussion are taught in a very wholesome way, tying in all sources– from Chinese to Hawaiian medicine– with respect and diligence to the source of his knowledge. After having gone to traditional schools for 16 years this is profoundly the BEST class I’ve ever taken. ~ Jennifer Ruggles


Being part of Earth Medicine Institute and absorbing our teachers knowledge has been AMAZING. It’s like opening a book with many books inside. I believe our nature as human beings is experiential. At EMI, we experience the plants, the wisdom they want to share and feel their medicine. Our consciousness is opening more and so the connection with Mother Earth. I’ll never see “weeds” the same way ever again! ~ Maria Arroyo



It was truly an honor to study with David. His class was completely wonderful. I am so grateful to have him as my mentor and I look forward to many collaborations in the future! Mahalo for your wisdom. ~ Deanna Rose, Indigo Herbals
