Greg Mast specializes in complex insurance coverage and business litigation for domestic and international insurers. Having spent time as both a law clerk and in-house counsel, Greg has earned a reputation as a respected advocate inside and outside of the courtroom.

As a foundation for his legal practice, Greg spent two years working in the U.S. House of Representatives, where his legislative responsibilities included, among other areas, cyberlaw and international affairs, and thereafter, he worked for a year as a judicial law clerk in a Georgia Superior Court. In 2004, he joined Fields Howell. While at Fields Howell, Greg was twice seconded to the Lloyd’s, London Insurance Market, serving as U.S. claims counsel and syndicate counsel for one of the market’s largest open market property insurers and treaty reinsurers.

With experience in government, the judiciary, in-house, and private practice, Greg brings a unique skill set to the practice of law. As a result, he is often retained to assist clients with complex insurance disputes across the country, including both first and third-party coverage as well as business disputes involving class actions, binding authority agreements, and insurer versus insurer conflicts.

In addition to his nationwide practice, Greg also heads up Fields Howell’s Tennessee office.
