Our approach

Bespoke guidance for your business
While all businesses operate under the same tax legislative and treaties framework, each has distinct goals, structures, and constraints.

We deliver concrete solutions designed around your organization and strategy. Our work is driven every day by transparency, responsiveness, and precision.

We believe in building enduring relationships founded on expertise, availability, and a clear understanding of your environment.

Keen insight driving excellence in tax law

Behind every successful international strategy lies rigorous foresight and a deep understanding of tax challenges.

After several years of advising companies on tax issues linked to international expansion, I founded Phronesis Avocat with a clear conviction: taxation must be mastered to secure and support global development. Inspired by Aristotle’s notion of phronesis (practical wisdom, professional prudence), I chose to combine technical expertise with strategic judgment to deliver reliable and tailored solutions.

My goal? Providing executives and finance teams with bespoke support, enabling them to move forward with confidence in a complex and ever‑changing environment.
