George Van Horne


Senior Managing Engineer


George is a forensic mechanical engineer with thirty-nine years of experience in understanding how mechanical systems work and why they do not. This experience, combined with his education, specialized training, and innate curiosity, has become a valuable tool for insurance adjusters and attorneys who need to understand large or complex losses. He has a proven history of providing clients with an accurate assessment of their situation and, typically, timely notice well before other parties are aware of the same information. George is an experienced expert witness, having provided testimony at depositions and arbitrations. More important, his credentials and attention to detail result in his testimony withstanding the strongest scrutiny. He has exceptional experience in origin and cause determinations for boiler explosions, industrial fires, and combustible dust explosions. George has formal training and credentials in Process Safety Management (PSM). He is also certified by the International Code Council (ICC) as both a plumbing and a mechanical inspector. His expertise with heating, ventilating, and air conditioning (HVAC) extends to indoor air quality investigations and moisture intrusion. George is specifically trained in investigating construction site and workplace accidents involving cranes, product and component failures, and standard of care reviews.
