Our Philosophy


We believe that lawyers serve not only their clients but the broader public interest. Legal representation is the primary mechanism through which individual rights, business activity, free choice, and societal order are protected. For this reason, our commitment to legal ethics and client care is unwavering. We combine deep legal knowledge with strategic insight to deliver clear, effective, and cost-efficient solutions, whether in a courtroom, in arbitration, or across the negotiating table. Our practice is rooted in respect for the law, legal ethics, and the imperative to act in good faith. We strive for excellence in every matter entrusted to us.

Dispute Resolution


Our litigation philosophy is proactive but pragmatic. We begin each case with extensive legal counseling and written opinions to fully brief our clients on risks, merits, and possible outcomes. Where appropriate, we actively pursue settlement before litigation, including through negotiation and alternative dispute resolution methods. We advocate for the use of mediation and arbitration as efficient, enforceable, and discreet alternative methods to dispute resolution.


Where litigation is required, we pursue it with diligence, precision, and strategic clarity, always aiming for timely and economically sound outcomes. We have successfully represented clients in landmark cases before the Supreme Court of Greece and in complex international arbitrations.
