Who we are
Storymentor is Greece’s only nonprofit dedicated exclusively to the art of storytelling. We use stories as powerful tools for communication, empowerment and change.
Drawing on techniques from theatre, narrative theory and classical rhetoric, we help organizations, businesses and individuals use storytelling strategically -to communicate with authenticity, build trust and promote their vision and work with clarity and impact.
Beyond training, we design and deliver original storytelling programs that bring to light issues often overlooked in public discourse -from gender inequality and the “glass ceiling,” to the emotional impact of cancer and the stigma surrounding failure.
At Storymentor, we believe stories can do more than inform.
They can connect. They can move. And they can make change happen.
