Narcissa was formally trained and graduated from the Farmacy Herbs certificate program in 2010. She then trained under beloved southwest herbalist JoAnn Sanchez for five years, making herbal medicine, tending to the herbal medicine gardens and helping to run Sanchez’s herbal diploma program at The Southwest Institute of Healing Arts in Tempe, Arizona. Narcissa found her way back to Farmacy Herbs in 2017 (Just couldn’t stay away!) and has been an integral part of the team ever since.
