  • Brian Vincent Manchester

    I have known Ron for several years. He is not only a fine lawyer he was my instructor at one of the ACS training seminars at Axion Labs in Chicago. Furthermore Ron used to work in a state forensic lab testing drugs and alcohol. Ron brings a rare skill to the courtroom having actualy done everything the government witnesses are testifying about. That is a combination that is hard to beat. I myself would trust Ron to represent a family member if it was necessary. Mark is a great lawyer and defender of the accused.

  • William Alton Young Jr.

    Ron Moore is a highly qualified DUI defense attorney with a unique background that gives his clients an edge. He understands the forensic science behind blood and breath testing because he used to work for the state's crime lab. Mr. Moore's mastery of scientific evidence in DUI cases is nationally recognized within the DUI defense community, and Mr. Moore is an active member of the National College of DUI Defense. Furthermore, Mr. Moore practices in a preeminent firm equipped to handle the most complex and difficult cases. I wholeheartedly recommend him.
