His wide range of transferable skills allow him to be an asset in multiple professional arenas.

Georgios is a firm believer of empirical research and to that extend he continuously explores the limits of human ability by putting his body and mind to the test. His passion for adventure has seen him take on some of earth’s greatest challenges and in doing so he has actively supported medical and environmental non-profit organizations raising public awareness for their efforts. In the year 2000, he swam the English Channel in the world’s fastest time for the year, earning him the English Channel Association’s Rolex Award. In 2004, as a member of the Greek national climbing team, in addition to his role as the team’s scientific advisor and medic, he climbed to the summit of Mount Everest from the notorious northern side route in the Tibetan Himalayas, and became the 1st Greek climber to do so from the northern side route. In 2011, after years of planning, organizing and training, he swam non-stop from the mainland of Greece in the Peloponnese to the island of Crete, covering a staggering distance of 101km, and became the 1st person in history to swim across the treacherous waters of the open Aegean Sea. In 2015, he completed the 250km Marathon des Sables ultra-running race, a 7-day self-sustained event in the heat stricken Sahara desert, dubbed by Discovery Channel as the ‘Toughest Footrace on Earth”. In 2019, Georgios successfully reached the summit of Mt Everest for the second time, again via the northern side route in Tibet; his journey to the summit was followed and documented by the Greek newspaper Kathimerini.
Following the successful undertakings of the Mount Everest climb, the English Channel swim and the Marathon de Sables run, Dr Georgios-Ioannis Tsianos became the first person in world history to successfully complete three of the most demanding challenges under very diverse and extreme environmental conditions.
