‘Unlike many criminal lawyers, they have an excellent understanding of legal issues surrounding large corporations, their management personnel and clients, including white collar crime.’

‘Although there are a couple of other good criminal lawyers dealing with white collar crime, IG law firm is in reality the only highly specialized law firm with the necessary depth to fully support big commercial and industrial companies in their cases that may have criminal aspects both in terms of advice and in cases of litigation.’

‘I don’t believe Prof. Giannidis needs any introduction, since we are talking about one of the most senior criminal lawyers in Greece in general. Panagiotis Koureleas is an exceptional criminal lawyer, obsessed with details and preparation of the case, that at the end of the day will make a difference before the bench. In many cases we worked together he managed to convince the Public Prosecutor to dismiss charges without submitting the case to the Court, against all odds. Very intelligent and a natural born litigator.’

‘They have deep technical knowledge of criminal law and all kinds of criminal proceedings in Greece, alongside a very strong business acumen. They package both in a corporate way that can be perfectly fit with multinational companies and international clients.’

‘Excellence in performance, professionalism and statistically high positive results in Courts. Exceptional performance for Mr Giannis Giannidis and Mr Panagiotis Koureleas.’

‘Partner professor Giannidis is the undisputed dean of Greek criminologists; he is very highly regarded by the judiciary, respected by his competitors and feared by the adversaries. His deep knowledge and experience, his exceptional politeness and eloquence combined with his practical, down-to-earth approach, makes him a first-class criminal lawyer.’

‘Prof. Ioannis Giannidis, a brilliant criminal law mind and a renowned professor with vast experience and knowledge on corporate criminal law and white collar crime, who has a unique ability to see the bigger picture.’

‘Panagiotis Koureleas, a person that business loves to work with. He is direct in his communication, inspires confidence, is fully updated on his field of expertise, an excellent litigator, very responsive with a charisma to think proactively and in a practical way. He has also a unique talent to explain complex criminal law issues in a comprehensive manner.’
