About Thomas

Thomas B. Song represents California employers in both single plaintiff discrimination and wage-hour class and collective actions.  In addition to litigation, Song also has an active advice and counsel practice, and enjoys providing timely and effective advice to employers on a broad range of employment issues.

Song also has extensive experience in Cal/OSHA compliance and litigation.  As prior legal counsel to the Cal/OSHA Appeals Board, he uses his unique background to provide tailored and effective advice regarding the myriad of California OSHA laws and compliance issues.  He is especially passionate about helping companies throughout the entire inspection, appeal, and hearing process, and is always looking to achieve the best possible result.

Song has successfully worked with OSHA to settle numerous citations in favor of his clients, including many involving serious and/or fatality accidents.  When settlement is not an option, Song has personally and successfully defended dozens of appeals before the Cal/OSHA Appeals Board, including several complete dismissals of Serious and fatality-related citations. Song also uses his inside knowledge of Cal/OSHA as it relates to the duties and responsibilities of primary employers (staffing companies) and secondary employers, and advises companies on how to best minimize liability in a joint employer context.  

Besides his proven advocacy in the courtroom and before administrative tribunals, Song is also a seasoned litigation attorney, having prevailed on numerous motions to dismiss, motions to compel, and summary judgment motions.  Song also has extensive experience in petitioning for writs of mandate, and has argued before multiple California Courts of Appeal as lead counsel.

Prior to becoming an attorney, Song was an officer in the U.S. Navy, and served on a guided-missile cruiser and as a nuclear engineer on the USS Abraham Lincoln (CVN-72) aircraft carrier. He is a graduate of the U.S. Navy Nuclear Power Program, the Defense Language Institute (DLI), and served as the foreign exchange officer to the Korean Naval Academy.
