While in the government, Mr. Stewart held the position of Laboratory Director and Chief Forensic Scientist for the United States Secret Service.

During his career, he has worked some of the most difficult cases imaginable. These often are avoided by some examiners as they routinely bring the strongest levels of scrutiny and cross examination. As a result of his testimony in the Martha Stewart trial, he was formally charged with perjury and then subsequently found “not guilty” by a jury. Mr. Stewart has always prided himself on his integrity and ability to handle the most difficult of casework.
