Giannis is a bright person, with a strong and optimistic personality.
The fact that he was born with a hand impairment did not prevent him from achieving great athletic, unusual achievements. However, alongside competitive sport, he also had an important professional career in marketing and sales, with many experiences and collaborations in Greece and abroad.
He is the first and only (so far) Greek athlete with a disability to complete the Ironman Triathlon marathon race. A fact that was captured in the award-winning documentary film “Our Limits”.
Motivational Speaker
As a motivational speaker, Giannis manages in a truly humane and genuine way to connect with his audience through his speeches or narratives, making his listeners realize that nothing in life is impossible if you want it bad enough, you prepare for it properly, you believe in yourself and your team while operating with vision and strategy.
He founded the non-profit crowdfunding platform, which has supported hundreds of efforts of ordinary people and organizations to fulfill dreams and goals.
