Praised as ‘extremely reliable' and 'very experienced’, Ioannis Giannidis Law Firm is widely acclaimed for its expertise in fraud and corruption cases, with particular strength in handling criminal cases with a political or VAT component. Practice head Ioannis Giannidis is a 'top practitioner’ in the field, with an extensive track record in representing foreign banks and other multinationals in financial crime, breach of trust, money laundering and corporate criminal liability matters.

Practice head(s):


The Firm is very responsive and client orientated and efficient.

Giannis Giannidis has very sound academic capabilities in his capacity as Professor at the University of Athens and a broad overview and practical experience in white collar crime matters.

Panagiotis Koureleas is a valuable colleague and very experienced in this area.

Mr. Giannidis is fairly & undisputedly considered as the top practitioner in his practice. However and most importantly, this is not an outcome of his impressive academic credentials as a Professor of Athens’ Law School, but is based on his profound proficiency, tremendous and unparalleled case track record.

Mr. Panagiotis Koureleas role was also paramount. He is considered by the market as a top tier criminal law practitioner with in depth and hands on knowledge on these matters and also personal participation in high profile cases with impressive positive results.’

The team is extremely reliable, quick in answering to questions, very experienced and capable to provide complete and clear advice on the most complex matters.

Professor Giannidis, the managing partner of the firm, is the counsel every client would want to work with: extremely knowledgeable, calm and patient, he is able to explain the most complex thing with clarity, leaving the client confident that a solution will be found (which afterwards comes out to be true). He quickly identifies the issues and shows the various options to the client, guiding him through the many pros and cons.

To my view, Ioannis Giannidis Law Firm is the best law firm in Greece for corporate criminal law and white collar crime. They are specialised corporate criminal lawyers combining in a unique way their criminal law expertise with a deep understanding of the corporate environment.

Their advice to us is always practical, business oriented and to the point, making them excellent interlocutors for in-house peers. Last but definitely not least, they manage to be always very responsive despite their workload. It is a practice I can trust and rely on.

Prof. Ioannis Giannidis, a brilliant criminal law mind and a renowned professor with vast experience and knowledge on the sector and a unique ability to see the bigger picture. 

Panagiotis Koureleas; he inspires confidence, is fully updated on his field of expertise, an excellent litigator, very responsive and with a charisma to think proactively and in a practical way.
