Gatsos Tsoumanis & Associates Law Firm

Theodossis Gatsos and Panagiotis Tsoumanis started their carriers in early ’80s. By the time the firm was formed, each of the founding partners had already achieved considerable professional prominence emanated from similar backgrounds but distinctive practicing skills and scientific interests. They decided to form Gatsos – Tsoumanis & Associates Law Firm by merging the law office of Theodossis Gatsos with the law office of Panagiotis Tsoumanis bringing together their long established experience and knowledge of clients’ needs.

The emerged Law Firm has been dedicated to offering “tailor-made”, insightful and effective legal services to meet our clients’ advisory, litigation and transactional needs. We work diligently, providing clear and comprehensive legal support to meet the new digital, economic, environmental and political challenges our clients face. This includes finding the best solutions for our clients’ complex matters with the aim of providing transformational advice and defending their litigation.

While we are constantly evolving trying to meet the new challenges we are proud to hear our clients keep saying that we successfully provide them the full range of legal services required to implement their strategies and/or to resolve their disputes. The core principles that guide our conduct and rule our practice are: honesty, confidentiality, integrity, independence, solid understanding of the business sector, deep scientific knowledge of each case we undertake the responsibility to handle and avoidance of conflict of interests.
