Alan Carroll “A.C.” Nash is a senior civil defense attorney and business leader whose practice focuses on the defense of insureds, corporations, and public entities in complex, high-exposure litigation. He concentrates on negligent security, wrongful death, product liability, automobile and commercial transportation claims, liquor liability, construction liability and premises liability matters.
A.C. also maintains a substantial public-sector and municipal defense practice, representing municipalities and law enforcement agencies in state and federal civil rights litigation, including claims alleging false arrest, malicious prosecution, and excessive force. His experience in this space includes defending matters throughout Florida in both trial and appellate courts.
A.C. serves as the Casualty Supervisor of the Fort Lauderdale office of Marshall Dennehey, where he oversees the day-to-day operations of the casualty department and leads a large team of attorneys handling complex and catastrophic-loss cases. In this role, he is responsible not only for legal strategy and quality control, but also for client relationships, attorney development, and overall practice performance.
Before joining Marshall Dennehey, A.C. was a trial associate at a Fort Lauderdale-based law enforcement and municipal defense firm with more than 30 years of history. Working closely with firm leadership, he played a key role in defending public entities and law enforcement officers in high-stakes civil rights litigation across Florida.
A.C. earned his juris doctor from Florida State University College of Law in 2007. While in law school, he served as a certified legal intern with the Second Judicial Circuit, trying approximately 40 jury and non-jury criminal cases. He was a member and coach of the Mock Trial Team, served as a student ambassador and traveling recruiter, sat on the Dean’s Cabinet, acted as the Fifth Circuit Governor for the American Bar Association, and received the Distinguished Pro Bono Award upon graduation.
A South Florida native, A.C. earned his undergraduate degree in Public Relations from the University of Florida, graduating early. Prior to law school, he worked in public relations and marketing, including managing state and national accounts for a Miami-based firm and later executing advertising and marketing programs for two Fortune 100 companies. This background continues to inform his approach to client development and litigation strategy.
A.C. is deeply committed to mentorship and community involvement. He mentors students at the elementary, secondary, undergraduate, and law school levels and has served in leadership and advisory roles with multiple professional and civic organizations.
