Dallas Attorney Clay Cosse

Clay Cossé brings to the firm an extensive record of success in a practice spanning products liability, trucking and transportation, premises liability, construction, toxic torts, commercial, and even admiralty and maritime litigation. Clay has even successfully defended a claim against a faithful performance bond arising out of allegations of judicial misconduct. Since graduating from Louisiana State University Law School in 2006, he has successfully defended clients in these arenas via summary judgment, mediation, motion practice, and trial. Clay has had the pleasure of counselling and advocating for clients ranging from Fortune 500 companies to small businesses. At Hartline, Clay focuses on products liability and catastrophic personal injury defense.

Before attending law school, Clay had the privilege of studying the classics en route to earning his Bachelor of Arts from the Program of Liberal Studies at the University of Notre Dame. There, Clay whet his appetite for one-on-one, adversarial competition by serving as president and participant in Notre Dame’s Bengal Bouts, a charity boxing tournament serving the Holy Cross Missions in Bangladesh.
