Marilena Babali
SoMe & Newsletter Coordinator
Marilena is an International and European Relations graduate, a die-hard traveler, and lover of both people and animals. She can charm you in 4 languages, and loves a good conversation starter.

This year she’s part of the Social Media & Newsletter Team, which fits her perfectly since she also works part-time as a social media manager. She believes that everyone can do their part in changing the world for the better, and her biggest flex is that she recently gave a speech at the United Nations in Geneva.
Andrew Garifallos
Experience & Side Events Project Manager
Andrew dedicated his early years to swimming, and later on to water polo, following his grandfather’s and father’s footsteps. After his identity as an athlete, Andrew decided to become professionally active in the sector he loved the most: water sports. Today he is considered to be the founding father of Beachpolistas World Tour, which started in Greece and is now international! The success of the tournament can be found in the growing number of the events and participants every summer. Along with the Beachpolistas World Tour, he has taken part in organizing numerous sports events. Andrew is the owner of FAB Sportswear, a Greek family-owned athletic apparel company, which specializes (guess where) in swimming, water polo, diving, synchronized swimming, open water swimming and any sport related to H2O. He is one of these “forever students” at the Athens University of Economics and Business, as he never seems to find time to open his books when he has so many responsibilities running his own business! Information of vital importance: he is a pescetarian and has three fur-children-puppies, Gemma, Zizel and Mr Tofu.

The people that define her as a sunshine with unflagging enthusiasm, a rainbow that can’t be let down.

By volunteering and assisting to the cause of TEDxATHENS she is positive that she will find what she is looking for, not only by hearing the speakers and what they have to say about the world, but also by working together with her fellow volunteers and people that she has met in this journey that is called TEDxATHENS.
