Michael L. Simes Partner

Over the past decade, Michael has devoted his practice to litigating and trying complex contractual disputes across the country, with a focus on the United States District Court for the Southern District of New York and the Commercial Division of the New York State Supreme Court.

Michael has secured summary judgment and other pre-trial victories on matters collectively worth more than $600 million for parties ranging from large international banks to officers and directors of closely held corporations. Michael successfully tried two separate post-acquisition contractual disputes, each with more than $20 million at stake. Michael’s extensive trial experience has led to him being regularly asked to participate in client “roundtables” to provide feedback on strategies for upcoming trials. Michael also helps to run the McGuireWoods Trial Advocacy Academy, helping to prepare the next generation of trial lawyers for the firm. Along with his background in complex commercial litigation, Michael has broad litigation experience in financial services, adversary actions in bankruptcy and reorganization proceedings, internal investigations, and regulatory inquiries.

While earning his undergraduate degree from Rollins College, Michael was honored as a Nina O. Dean Scholar.
