What our students are saying

“This calling of the plants is deeper than a profession or a hobby. The true herbalist is not designated by any certification or degree; our mark is invisible, for it is inscribed into our hearts by the hand of Nature itself.”
Sajah Popham

Meet Your Teachers

Herbalist, Mother, Teacher, Birth & Postpartum Doula, & Steward of Casa Curativa

Julia Bentley, originally from Tennessee (ancestral territory of the Cherokee people), found her path into herbalism through her own healing journey from eczema and psoriasis. After studying with Sajah Popham, Julia moved to Lake Atitlán, Guatemala, where she founded Casa Curativa, a sanctuary where people from all over the world can connect with the healing power of plants.

A humorous and engaging teacher, Julia blends lightheartedness with deep wisdom, encouraging students to laugh and find humility in their practice. Her lectures on alchemy and the spagyric arts invite exploration into the more mystical aspects of herbal medicine. Julia’s entrepreneurial spirit shines through in her work, as she has cultivated Casa Curativa into not only an educational hub but also a thriving herbal brand, focused on quality, ethics, and community.

Living onsite at Casa Curativa with her son Emmitt, Julia continues to steward the sanctuary, nurturing both the plants and the community that surrounds it. Her teaching inspires students to embrace both the practical and the profound in their herbal practice, empowering them to create their own path in the world of herbalism.
