My values


You should expect from your lawyer not only sound advice and a robust defence of your interests, but also safeguarding under any circumstances. If your case contains gaps which reduces the chances of success, it is our duty to inform you.


It is important to me that you are able to implement the advice you receive from your lawyer. I always strive to make our legal opinions understandable and capable of being put into practice. I will be happy to assist you in implementing the advice you have received.


It is always easier to give a legal opinion or document that is complex and exhaustive. It is much harder to make it synthetic and understandable for everyone. My challenge is to make the application of law as easy as possible!

My approach

We founded BSR Avocats in order to bring a different answer, a more personal and human approach to private and commercial clients.

I will be happy to meet you and study the best way to assist you.
