Chambers USA and Chambers Global (2012 to 2017) rank Dan as a leading arbitration lawyer. Chambers calls him “a star in the international arbitration world” and “an extraordinary legal talent and is extremely creative in the legal theories he uses.” He is “particularly praised for his astuteness” and “always two steps ahead of the other side”. “Clients and peers overwhelmingly attest to his expertise as ‘a very skilled advocate’ who ‘comes up with practical, commercial advice that clients find extremely useful.’” The publication also notes his “tremendous expertise in pursuing arbitrations in Asia” and describes him as a “very talented and knowledgeable individual who has an exclusive focus on arbitration.” He has been ranked an “International Arbitration Star” and a “Litigation Star (General Commercial & Securities)” by Euromoney Benchmark Litigation (2010 to 2017 Edns).

He was lauded as being “
alert, informed and bold in arbitration proceedings” and for his “acumen and knowledge of local law” and “simply amazing ability to remember arcane, technical details from evidentiary findings, and quote them in detail.” The Global Arbitration Review calls him “a name to know” and commends his “impressive attention to detail and strategy” and “innovative ways of presenting complex ideas to a multilingual and multi-jurisdictional tribunal.” The GAR notes his “easy to work with approach” and remarks that “Clients love him.” Euromoney Institutional Investor ranks Dan as an Expert in Commercial Arbitration. Legal 500 Asia calls him an “outstanding lawyer.”

These cases involve disputes stemming from joint venture and partnership agreements, distributor and supply agreements, patents and IP agreements, license agreements, noncompete agreements, share purchase and option agreements, construction and oil & gas contracts. 

Dan has over a decade of international arbitration and litigation experience at some of the largest international law firms. He previously practiced with Latham & Watkins and O’Melveny & Myers in New York, and Lovells in London, where he represented US and international clients in high-value cases spanning a range of national laws and industries, including aerospace, construction, telecommunications, entertainment, pharmaceuticals, manufacturing, oil and gas, and energy.
