Paragliding  instructor

I started paragliding in 1998. After my first landing, then as a passenger on a two-seater addiction flight, it was an one-way call for me!”Almost three years later I had already won a Greek championship and I started traveling abroad, trying to satisfy my thirst for new experiences, new acquaintances but above all to fly to as many different places as I could. In the effort to make this passion of mine a reality, I started to fly competitively and non-competitively in the world's most famous paragliding areas, such as: Owens Valley, Annecy, Piedrahita, Tirol, Cornizzolo, Fiesch, St. Andre, Tolmin, Ibaraki and many more!My request, and my goal, after all these years is to introduce paragliding to as many young pilots and passengers with responsibilty and safety. My satisfaction is to see bigger smiles after each landing !
