Mayer Brown expands International Arbitration practice with addition of David Weiss


Mayer Brown announced today that international arbitration lawyer David Weiss has joined the firm as a partner in Houston, further expanding the Houston office’s international arbitration bench. David joins from King & Spalding.

David’s background includes substantial experience in investor-state arbitrations, commercial disputes in Latin America and international arbitrations among parties in the energy industry. He also has significant experience regarding post-M&A disputes. David’s strong language skills, which include fluency in Spanish and Portuguese, add flexibility for putting cross-office teams on complex matters across the firm’s global practice, including its offices in Houston, Brazil, London and Singapore.

“David is a seasoned international arbitrator and litigator, having played a lead role in several of the largest and most complex international arbitrations in recent years, is truly valuable to our team, and we are delighted to welcome him to our growing international arbitration practice around the globe,” said Raid Abu-Manneh, global co-head of Mayer Brown’s International Arbitration group. “Businesses around the world are navigating a changing international arbitration landscape. David’s experience in energy disputes, coupled with his focus on commercial and investment disputes in Latin America will immediately benefit the firm—in addressing immediate client needs in our Houston and Brazil offices.”

David’s extensive experience in advocacy before international tribunals includes participating in proceedings before the International Centre for Settlement of Investment Disputes, the International Chamber of Commerce and the Permanent Court of Arbitration in The Hague.

“Mayer Brown’s global footprint, leading international arbitration practice and unparalleled brand for advocacy were very attractive to me,” said David. “Those attributes combined with Mayer Brown’s strength in the energy sector and Latin America, especially Brazil, presented me with the perfect opportunity to take my practice to the next level.”

Neil Wasserstrom, the managing partner of Mayer Brown’s Houston office, added, “David brings additional top-quality experience in high-profile and high-value international arbitrations to our Houston office, and reinforces our global capabilities for energy industry clients.”

David joins Mayer Brown’s global team of over 100 lawyers engaged in international arbitration across its offices in the US, EU, Brazil, the Middle East and Asia.
