New Jersey retail store expert witnesses assess store operations, safety programs, and loss-prevention practices across supermarkets, big-box retailers, and dense mall corridors from Newark to the Jersey Shore. They often come from retail management, OSHA compliance, human factors, or security backgrounds, with experience in high-traffic environments shaped by Turnpike and PATH commuting. They evaluate slip-and-fall causes, aisle obstructions, lighting, surveillance, staffing, and inspection protocols.
