Professional Congress Organiser

The ITA-AITES World Tunnel Congress – WTC 2023, in Athens, will be organised in co-operation with the professional conference organiser CONVIN which has been involved in the bidding procedure. They are seasoned executives who have been working in major conference-organising companies for many years. Thus, CONVIN and the GTS have decided to join forces, combining the knowledge, experience and security that a major company can provide with the flexibility, speed, low cost, creativity, versatility and personal assistance, which are the hallmarks of a small business. CONVIN has taken away the bureaucracy and added directness, innovation and state-of-the-art IT applications in order to generate significant added value to any conference.




CONVIN is a dynamic enterprise, founded by specialists in planning and managing CONVentions and INcentives.

As a PCO our aspiration is to reach very high standards for services offered in our field. We aim constantly for innovation, inspiration and, at the same time, for the most practical solutions in every aspect of the events we undertake.
