We set up while managing the activities of the Yugoslav Association for Endoscopic Surgery – JUEH, the first independent professional association in the country and region, established in March 1996. and fully operational until 2003.

Everything in 2020 and, as we can assume, in 2021 is inevitably related to the COVID-19 Pandemic realities.

The pandemic our world is facing caught everyone by surprise at the beginning of 2020 and required us to manage amidst huge uncertainty: uncertainty as to when we can travel again, uncertainty as to when business events will return and uncertainty as to when the pandemic will be over.

Another key consideration in this situation is the importance of remaining optimistic. ARIA.ONE remained optimistic, shared and communicated with our partners, and therefore this pandemic has opened our eyes to new opportunities that are arising from the uncertainty. Virtual events and have become the new norm (for now…). As all PCOs we are learning, understanding and specializing in this ONLINE world. This is exactly what ARIA.ONE is doing. We help to facilitate sharing and communication between for our partners. We are conducting successful conferences on virtual platforms and more is coming soon.
