Expert witnesses must have broad experience, impressive credentials, good communication skills, an analytical mind and stay calm under pressure. Dr. J. Paul Tullis, President of TEC has demonstrated these qualities in depositions and in court. He considers the ultimate teaching experience to be educating a judge and lay jury about graduate level engineering material in a few hours in a court room.
