Roland koronya
Founder. Biologist. Plant evangelist.
Roland Koronya is the core instructor behind and the founder of The Green Guild.
He holds a degree in Biology (Herbal Sciences, University of Pécs, 2012), where he built a scientific foundation rooted in plant medicine. But his real education came in the field — studying with and shadowing experienced clinical herbalists, learning how healing actually works in practice.
Over the past decade, Roland has taught thousands of students from around Europe, blending scientific insight with earth-based spirituality and a holistic view of health.
His teaching goes beyond “fixing what’s wrong.” It’s about supporting physical vitality, mental clarity, emotional resilience, and a deeper sense of purpose — all through the wisdom of plants.
For Roland, herbalism isn’t just a profession.
It’s a path.
And The Green Guild is where he shares everything he’s gathered along the way.
Dalma Koronya-Jung
Horticultural Engineer. Grower. Straight-talker.
Dalma runs her own garden. Not a metaphor, a real one, dirt and all. For 8 years, she’s lived and breathed the growing cycle, and she knows what plants can actually do.
She’s on a mission to hand people the kind of plant knowledge that’s useful, hands-on, and honest—because somewhere along the way, we forgot how close we used to be to the green world. She’s here to change that
