Testimonials

- The practice stands out for its professionalism, deep expertise, and strategic judgment in complex international litigation. Potential clients should know that the team is not only technically excellent, but also practical, responsive, and highly effective at coordinating cross-border disputes. I am particularly fond of Dennis Hranitzky and Alex Leventhal, who combine experience, creativity, and commercial awareness with a clear understanding of how international disputes unfold in practice. Compared to other firms, the team distinguishes itself through senior attention, strong collaboration across jurisdictions, and close personal connections with trusted local lawyers. That network is particularly valuable in cross-border matters, where effective execution often depends on knowing the right people on the ground and coordinating them well.
- Dennis Hranitzky and Alex Leventhal stand out for their professionalism, strategic judgment, and deep understanding of complex international disputes. What makes them different from competitors is their ability to combine sophisticated legal analysis with practical, cross-border execution. They are highly responsive, commercially aware, and effective at working with clients and local counsel across jurisdictions. I particularly value their international mindset and strong personal connections with trusted local lawyers. Dennis and Alex also excel in other languages, including Spanish and Portuguese, which is a significant advantage in Latin America-related matters and helps build trust, avoid misunderstandings, and coordinate strategy more effectively.
- The partners that I've had the pleasure of working with have always had deep sectoral and industry knowledge, have been strategic in their thinking, are collaborative, and outcome-oriented. John Quinn, Dennis Hranitzky, and Anthony Sinclair have been standout individuals to work with on this front.
- The team is extremely strategic and outcome-oriented in its advice, bearing in mind the end goals of the client. The team has deep knowledge and insight into the market and is collaborative in its approach to cross-border litigation strategies.
- They have connected with the client and completely understood the client's priorities, tailoring a strategy focused on those priorities. They are flexible in their thinking and able to adapt the strategy in accordance with the client's needs. They are able to litigate proceedings that are multidimensional, thus understanding how each one of them relates and how to improve the position accordingly.
