Learn MoreThis is not a “soft course” for dabblers. Bring your best, for David Winston will always bring his. Undoubtably one of the most gifted herbalists of our time, or any time, I think David’s greatest gift may be as a teacher. I am constantly in awe of his, and his team’s, dedication, professionalism, and wealth of knowledge. I was an online student, in what may have been one of the more challenging years, a.k.a. 2020 and the COVID-19 epidemic. But every week through personal and technological challenges, David persevered, and laying his years of research and experience out to eager listeners. He was challenging, provoking, and demandingly encouraging. I feel that I am going into the world of herbal medicine with possibly the very best foundation that exists. This course is possibly the most important and rewarding academic experience I have ever had.
