Andrew Huntley B.Sc., Ph.D.
Our Associates perform on-site investigations to determine origin and cause of complex losses. Their process: examine and collect evidence, take on-site photos, interview witnesses, conduct testing in our lab and analyze data to produce technical reports that are clear and concise.
