Our Teachers are the Heart of the School

Welcome to Our Stellar Lineup of Core Instructors!

We’re beaming proud to showcase this fine array of herbal teachers, writers and gardeners.

Our core instructors are the primary teachers in the Herbal Immersion Program. See our list of contributors below for all the instructors involved in the Herbal Immersion program. Asia Suler and Juliet Blankespoor are the primary instructors for the Medicine Making Course.

Juliet Blankespoor

Juliet Blankespoor started the Chestnut School of Herbal Medicine in 2007, after deciding to become a professional plant-human matchmaker. She lives with her partner Tom outside of Asheville, NC, in a wee handbuilt home where they nurture a medicinal herb garden and a delightfully hilarious daughter. Juliet has been sharing her passion for plants for over twenty-five years through teaching herbal medicine and botany. Despite a seemingly single-minded obsession for medicinal plants, she’s branched out in the last few years, exploring new territory and interests—namely photographing, videoing, and writing about: medicinal plants.

Juliet is an unabashed botanical entrepreneur –her earliest project during her collegiate years included a get-rich-quick-scheme involving papaya trees. After graduating from University of Florida with a degree in botany, Juliet founded and formulated a tincture line, Green Faith Herbals. She spent her twenties growing and wildcrafting medicine for her tincture business.

During this time, Juliet continued her studies by attending extensive herbal programs at the Northeast School of Botanical Medicine, the California School of Herbal Studies and the Southwest School of Botanical Medicine. Her teachers are 7Song, James Snow and Michael Moore.
After many years of teaching intensive, all-outdoor herbal programs, Juliet has decided she is a raging introvert and her teachings are best suited to the virtual sphere. She is currently writing her first bookCultivating Medicinal Herbs; A Guidebook to Growing Healing Plants in the Home Garden, which is slated to release in the summer of 2016. Juliet has spent the last few years videoing herbs, and their admirers and cultivators, for the Herbal Immersion Program, which will be ready next spring. She is delighted to continue to teach and connect with herb lovers through the ethers. Please visit Blog Castanea to enjoy her herbal articles and botanical photography.
