Jane Siegel has been a criminal trial advocate for the last 29 years. She owns her own private criminal defense firm in San Diego, California.

Before joining CLG as of counsel, Jane ran a successful solo-practice and quickly gained the reputation as the "go to" civilian defense attorney for high profile military cases.  

She spent 23 years in the United States Marine Corps as a judge advocate and retired as a full colonel. Colonel Siegel has practiced as both a prosecutor and a judge, although her heart is ever in defense.

She has tried in excess of 400 felony jury trials.  As a teacher of advocacy, the National Institute for Trial Advocacy certified Colonel Siegel as an instructor 19 years ago.  She has taught trial advocacy for the Navy and the Marine Corps lawyers all over the world.  Additionally, Colonel Siegel has taught advocacy for law schools and law firms all over the country including Stanford, the University of San Francisco and Cardozo.  She teaches for the National College of Defense Counsel in Macon, Georgia, and was the executive director of the Institute for Criminal Defense Advocacy in San Diego for four years.
