They're very bright lawyers who always make themselves available and dig in very deep with intellectual rigor. They're very team-oriented as well and they excel at condensing complicated strategic issues and finding the pivot points to focus on.
They're very experienced, hardworking, intuitive and smart. At the same type, they're very normal people that are easy to work with. They have long lasting relations with clients and really know their business.
Cleary has a deep bench of arbitration expertise and the cross-practice skills to litigate matters in any substantive area of law. They're strategically and discerningly aggressive - with the precision of surgeons rather than bludgeons. Their inter-practice work is where they really shine; it's a huge value add.
Cleary’s department stands out for its ability to handle complex, high stakes disputes with strong cross-border coordination and strategic clarity. The team combines significant depth at partner level with a strong and technically capable associate bench and they are consistently responsive, accessible, and proactive. Communication is clear and timely, even in fast-moving, high stakes matters involving multiple jurisdictions.
Their work is very fast and of very high quality. I always feel confident that they know what they're doing and, when you see the work, it's clearly of very high quality. They know the industry in detail, which allows them to have a thorough understanding of the commercial aspects involved. This, naturally, allows them to have a broader approach when drafting briefs or preparing for hearings.
