Trial Experience
Brent’s primary discipline is national trial practice. He began trying cases in Texas in the mid-1990s when he represented such companies as United States Gypsum, National Gypsum, GAF Corporation, Armstrong World Industries, Dana Corporation, and Union Carbide Corporation. He is the national trial counsel for The Boeing Company and Viad Corporation, an alleged successor-in-interest to Griscom-Russell Company, which made evaporators used aboard naval vessels. Viad Corporation has taken a strict no-pay policy and Brent has tried several cases to verdict on Viad’s behalf, and successfully obtained defense verdicts in each. Brent was a long-time member of Georgia-Pacific’s National Trial Team for its toxic torts litigation. He has tried cases and obtained defense verdicts in multiple states across the country.
