Matt takes a pragmatic approach to resolving high-stakes litigation that has earned him recognition from his peers and brings value to his clients.

He specializes in handling a client’s most complex matters. Matt’s experience extends to responding to government investigations, appearing in both federal and state courts, and participating in alternative dispute resolution.  He has dealt with all phases of litigation, whether it’s preparing the President of a Fortune 100 company to testify at trial or serving as the firm’s lead partner on a matter.

Matt has been a core member of the legal team on some of the firm’s highest-profile matters.  Most notably, these matters included recouping $4 billion for American Express from  Visa and MasterCard—the largest ever settlement for a single antitrust plaintiff—and representing a nationwide consumer class against Volkswagen based on the installation of an emissions testing defeat device, which resulted in a partial settlement valued at approximately $15 billion.

In addition to these litigations, Matt has counseled his clients in a wide variety of subject matters, including antitrust, contract, corporate governance, class action, entertainment, land use/real estate, intellectual property, securities, and estate litigation. 

Matt’s writing on the compact clause of the Constitution was published in the Yale Law & Policy Review and has been cited as authority by multiple courts.  In addition to constitutional law, Matt’s academic interests include political science, mediation, and land use.  He also sits on a local Zoning Board of Appeals.
