I believe they offered a unique approach to our shareholder dispute, and I can only describe that approach as an “all out attack”.

They were, for the lack of a better term, “cut throat” in their approach, and made sure to get the best outcome possible for the company.

Tarık Güleryüz never hesitated to take the necessary steps to ensure our success in the case.

Tarık Güleryüz offered a creative and comprehensive strategy that impressed us all. I believe he has a unique thought process that sets him apart from others and enables new and exciting angles to approach the problem.

It appears to me that they don’t see dispute resolution only as a matter of legal knowledge but as a matter of process management that takes a multifaceted approach.

Tarık Güleryüz has a never-ending energy, and anyone can see how passionate he is about his work. I had the chance to work with him in a shareholder dispute and I can tell that he is an exceptional lawyer in this field.’

I can confidently say that they are very knowledgeable on the ins and outs of shareholder disputes, and are not afraid to force every possibility to the very end.

Tarık Güleryüz was in the driving seat through our disputes. He excelled especially with his professionalism and hands-on approach. He made sure to understand every aspect of the cases and explored every possibility.
