The organizers of TEDxCharleston have announced the speaker line up for this year's event. Scheduled for Apr. 8, 2014, the theme is Ripple Effect, and the speakers were chosen for their ideas that are designed to create a lasting, ongoing ripple effect in areas such as the environment, education, parenting, philanthropy, technology, arts, healthcare and more.

TEDxCharleston is operated under a license from TED, a nonprofit organization devoted to Ideas Worth Spreading, the local independently produced event is an all-day immersion experience at the intersection of science, art, performance and business.

"We are thrilled to announce these speakers," said Edith Howle, curator of TEDxCharleston, in a release. "We know there are many unheard voices in the Charleston area and all of these speakers have an idea worth sharing. Our goal for this event was to gather inspiring people with diverse ideas that can have exponential impact on our community and our world. It's clear that with a line up like this, we've done just that. We all look forward to their talks and to being moved and motivated."
