Banking and finance

"Excellent and proactive service.”

"The banking team of Schellenberg Wittmer are highly skilled, efficient and understand the banking and financial industry very well."

"As soon as we started working with Tarek Houdrouge, we realised we had made the right decision: he could anticipate the key challenges we would face so that we could manage them proactively, he demonstrated an in-depth knowledge of the legal aspects of our work, but also a good understanding of the cultural specificities of our firm that helped us manage our project as efficiently as possible. Also, we felt he demonstrated a very strong sense of integrity, as he asked several times whether we preferred him or us to conduct some parts of the administrative work when it was not necessary to have a legal background to achieve the tasks – resulting in very reasonable fees, hence great value for money.”

Josef Caleff

Olivier Favre  

"He is extremely knowledgeable, experienced and solution-orientated. I was very satisfied with the advice provided by him.”


Tarek Houdrouge      

"Tarek Houdrouge is always very positive and solution-orientated. He has very good understanding of the banking industry, extremely good legal skills and provides pragmatic legal solutions."

"His key strength is that he demonstrates both a very strong in-depth legal knowledge in each specific banking topic I addressed with him, and very good communication/strategy skills. In the past, most lawyers I have worked with were either good specialists, but then not so good at managing relationships, projects, or deadlines. Or they were rather good 'salesmen', with very strong interpersonal skills and high-level vision, but limited in-depth knowledge when it came to details. In all my interactions with Tarek Houdrouge, he has demonstrated he has both, which I feel is very rare. It makes it extremely efficient and pleasant working with him.”
