Colorado athletic training expert witnesses assess sports and workplace injury prevention, evaluation, and return-to-play decisions. Many are certified athletic trainers working with orthopedic surgeons and physical therapists at UCHealth and CU Anschutz–affiliated programs. In Colorado’s high-altitude training and outdoor recreation environment, they address concussion management, heat and exertional illness, and sideline protocols. They commonly evaluate standard of care, documentation, and causation in musculoskeletal and head-injury cases.
