John is the Barclay Damon managing partner, having served in that role since 2000. During his time in leadership, John has guided the firm’s growth from 50 to nearly 300 lawyers and its transformation from a regional firm with three offices to a unique platform of smaller and major market offices from which a number of featured practice, such as Energy and Intellectual Property, are growing in national prominence.

John serves a large roster of clients as an experienced business trial lawyer. In both state and federal courts, John represents corporate and individual clients in a wide array of business disputes involving fraud, breach of contract, and tort liability exposure.
