We also perform EDR (black box) downloads and analysis, expert witness testimony, scene and evidence photography, full supporting 3D graphics and animation, and much, much more.

McNally & Associates accident reconstuctions are drawn on detailed and extensive experience in the reconstruction field and service in the law enforcement community. We have participated in hundreds of staged test collisions, reconstructed thousands of collisions, lectured at reconstruction-related seminars, and provided expert testimony in dozens of local, state, and federal courts. All McNally & Associates reconstructionists are ACTAR-certified.
