Growing up in the border state of Texas (USA), she fell in love with the rich culture and traditions of Mexico. After her father was diagnosed with cancer, she began to study the use of healing plants and energy medicine among the local Mexican “curanderos” in her region. Her research into integrative therapies to complement western medical interventions led to a master’s degree in acupuncture and Traditional Chinese Medicine and a thriving practice in New York City.
Jessica’s research into ancient and shamanic healing practices led her to the mountains of Ecuador. Deep in the Andes, she experienced a profound personal transformation as she dedicated herself to learning the ways of holding space for ceremonies using master plants, the four cardinal directions/the four elements, the temazcal (sweatlodge) as well as traditional medicine music Her dedication to this path led her to return to her roots in Mexico to work with the ceremonial traditions of psilocybin-containing mushrooms. She currently works as a guide and a retreat organizer creating unique and beautiful experiences with deep respect and gratitude for the traditions that have transformed and enriched her life. As a member of the facilitation team at Synthesis Jessica is thrilled to connect the benefits of modern science and ancient wisdom as a tool of positive change in this ever-changing world.
