Having been a student of David’s, it’s been fascinating to me how many times I pull on not just the herbal knowledge I learned from him but the deep well of wisdom which David transmits. I find myself referring to him when I’m talking about how we heal as a culture or how we honor the earth. The learning I carry with me from the Herbal Studies Program bubbles up in profound ways in so many parts of my life. I think that’s part of the magic of his formulations: his spirit is behind each one.  Maia Toll
