Colleeen Bingham Colleen Bingham

Colleen Marie Bingham began developing her first products as a young child, playing with the soaps and perfumes she found hidden in cupboards. As an adult, she discovered that every ingredient was special and had its own story from where it was grown to when it was harvested. These unique stories taught her that the source and quality of each ingredient would define her health and her impact on the planet. She learned how to refine her choices in the food she ate and the products she bought to slather on her skin. Then in 2010, she signed up for her first herbal studies class, made her first batch of natural skincare, and began her journey as a product formulator and herbalist. Colleen's knowledge of whole plant medicine fused with her topical formulations resulting in the creation of her product line, Poppy Botanicals . Colleen is Lab Manager, Medicine Maker and an Instructor at The California School of Herbal Studies, and is developing and producing natural, plant based beauty products for companies nationwide.

diana de lucaCourtney Fischer
herbalist, MS, CNS

Courtney finds plants and their medicine to be intriguing as well as offering a meaningful connection to the earth and what it means to be alive. Many years ago she was first inspired by the medicinal plants in her own backyard, in awe that they not only had the ability to rouse various helpful effects within her when consumed but that this medicine was also so accessible—she has been inquisitively learning about plants, the human body/mind, and healing ever since. She began her herbal studies at Motherland Botanical Sanctuary and CSHS, and then went on to receive her Masters in Herbal Medicine from Maryland University of Integrative Health.
