Founded in 2009, Diligence was born from a vision to bridge the gap between organizational potential and actual performance. We recognized that many businesses struggled not from lack of talent, but from insufficient training and strategic guidance.

Over the past 15 years, we’ve grown from a small training consultancy to a comprehensive professional development partner, serving over 150 organizations across 10+ industries.

Today, we’re proud to be recognized as a leading provider of training and consulting services, certified by AvΑΔΑ and trusted by industry leaders throughout Greece and beyond.
