Gavin specializes in class action and complex commercial litigation, representing corporate and institutional clients. Consistently recognized as a leading commercial litigator, Gavin has been described by clients as “excellent” and “very thorough, detail-oriented, and extremely intelligent” (Chambers USA).

Gavin’s interest in military history has served him well in successfully defending corporate clients in securities, shareholder derivative, class action, consumer fraud, mass tort, and RICO claims. Approaching every matter from a strategic angle, he surveys the state of play, assembles facts, determines tactics, and deploys a clear-sighted grand strategy to achieve his clients’ business goals. Gavin effectively manages massive claims and supervises large teams of lawyers while remaining the central point of contact for his clients.

Gavin has handled numerous jury and nonjury cases across the United States. He has argued before the appellate courts of California, Florida, Massachusetts, New Jersey, and New York, and before several federal circuit courts of appeal. He also handles other types of commercial litigation, from shareholder disputes to real estate and environmental matters.
