As Chair of the CSG Law Litigation and White Collar Defense & Investigations Groups and a former federal prosecutor, Matthew Beck brings exceptional skills and insight to representing companies, government entities, and C-suite executives in game-changing complex civil litigation, white collar criminal investigations, and securities enforcement matters. His broad practice also includes acting as outside general counsel for mid-sized private companies, managing their entire portfolio of legal needs.

Whether his clients are facing litigation, subjects of a government investigation, or need his outside general counsel practice, Matt is a problem solver who combines passion, proficiency, and a client-focused approach, finding the solution best suited to achieve his clients’ business objectives and positioning them for the future. 

A Business-Minded Advisor

Matt meets the myriad needs of his clients, helping them achieve their business goals through a combination of inventive yet practical risk avoidance strategies, creative problem solving, corporate governance counsel, and skill at leveraging the legal system to their advantage. His many long-term clients know he deeply cares about them and their issues and entrust him with resolving challenges that fundamentally impact their lives and businesses.

A Top-Tier Litigator

While at the U.S. Attorney’s Office where he was, among other roles, Chief of the General Crimes Unit, Matt oversaw cases, directed strategy, and trained new prosecutors. Among his most notable prosecutions, he led the successful investigation and precedent-setting prosecution of a multidecade, $37 million insider trading scheme that resulted in the longest-ever prison sentence for insider trading.

Knowing how prosecutors think and investigate companies and individuals, Matt excels at defending his clients in white collar criminal matters, regulatory investigations, and government enforcement actions. He has extensive experience with a wide variety of criminal matters including those involving securities fraud, insider trading, healthcare fraud, tax fraud, bank fraud, mail and wire fraud, honest services fraud, Foreign Corrupt Practices Act violations, cybercrime, identity theft, money laundering, and obstruction of justice.

In both prosecuting and defending litigation, Matt knows how to overwhelm an opponent to turn a difficult case into a winning one. At the same time, and when appropriate, Matt staffs matters leanly, understanding that overlawyering a matter, even if in a winning position, can effectively change a client’s legal win to a financial loss. Employing an individualized approach in every matter and each client experience, Matt combines a relentless work ethic, empathy, and fierce advocacy to achieve the best result in every matter.

A Recognized Leader

Matt has been recognized by clients and peers as a leader in his field. In addition to maintaining very active advisory and litigation practices, Matt is a member of the CSG Law Executive Committee which is responsible for the management and strategic direction of the firm.
