Matthew is a former federal prosecutor who clerked for two federal judges and handled high-profile cases at Skadden Arps before founding the Firm in 2013. He recently secured a landmark $1 billion preliminary injunction in a case he filed faulting the City and County of Los Angeles for their handling of the homelessness crisis and demanding government action to end homelessness in Los Angeles (see Matthew’s argument before the Ninth Circuit defending the preliminary injunction here ).

Among his current clients are a CEO who was recently charged by federal authorities in the FIFA soccer bribery scandal, several students implicated in the college admissions scandal, health care providers accused of submitting false claims, and a solar industry executive accused of trade secret theft.

In 2018, he won a $3.7 million verdict in a whistleblower case filed against a Los Angeles-area school district that fired its CFO and CEO after they raised concerns about corruption and bribery. That case resulted in an SEC proceeding against the district and criminal investigations of construction companies suspected of corrupt conduct throughout California.

Matthew was named Attorney of the Year by California Lawyer magazine in 2012 after defeating a False Claims Act case that sought hundreds of millions of dollars in damages.

Matthew regularly advises boards and conducts internal investigations, including an investigation on behalf of the Los Angeles County Bar Association. He has represented companies and dozens of witnesses in internal investigations and federal and civil investigations, including DOJ and SEC investigations of Snapchat. He has argued more than a dozen appeals before the Ninth Circuit.

His legal career began as a law clerk for legend-of-the-bar Plato Cacheris in Washington, D.C. Since then, he has been lead trial and appellate counsel in dozens of criminal and civil cases.

When not practicing law, Matthew ocean-swims, Pelotons, sings, and plays guitar , all with great enthusiasm and mediocrity. He lives in South Pasadena with his wife, Jenny who is an amazing college admissions consultant , and their two daughters.
