A Recent Case of Rare Asbestos Exposure

Ryan has experience helping clients who were exposed to asbestos in a variety of occupations, such as former aircraft and truck mechanics and oil refinery workers. One case he recently litigated involved Bryant, who at age 24, was a helicopter repairman in Louisiana. Bryant’s exposure to asbestos began in 1988 and continued into the late 1990s. At 48 years old, Bryant learned he had pleural mesothelioma. Thirteen months after his initial diagnosis, he passed away.

Ryan took the lead for the legal team assigned to Bryant’s case.

“We had to fully investigate the manufacturers of the helicopters and the products within in those aircraft to develop his case from the ground up,” Ryan said. “There were no usual suspects to start with, so it made the case more challenging than usual, and the good result even more remarkable.”

Ryan and his team were successful in working up the case against several companies and obtaining a favorable result for Bryant’s family.
