Sayles Werbner co-founder Mark S. Werbner is one of the nation’s most respected trial lawyers. His practice covers a broad range of law with an emphasis on complex business litigation, white-collar criminal defense, catastrophic personal injuries and wrongful death cases. He has represented both plaintiffs and defendants in more than 150 trials heard by juries throughout Texas and across the United States. His ability to translate high-stakes, complex legal matters into easily understandable language has enabled him to achieve an extraordinary courtroom track record.

Mark’s courtroom accomplishments include some of the largest jury verdicts in the country, and his work has been widely recognized by both his peers and the press. He is lead counsel for Terror Victims v. Arab Bank, a groundbreaking international terrorism lawsuit that has been featured on The Fox News Channel, Court TV, The Wall Street Journal and other national and international media.

In September 2012, Mark and fellow firm founder Dick Sayles successfully defended New York hedge fund Exis Capital Management in a multibillion-dollar fraud lawsuit. Mark’s work in the case helped Exis Capital earn complete dismissal of the claims on the eve of a scheduled six-week trial in New Jersey Superior Court, which spared his client from spending additional time and money in court.

In May 2011, Mark was part of a trial team that won a $63 million patent infringement verdict in a case heard in the Marshall division of the Eastern District of Texas. The verdict was recognized in Texas Lawyer newspaper as one of the Top 10 verdicts issued by Texas juries during 2011.

Sayles Werbner is celebrating its 20th year as one of the nation’s leading law firms with an informative brochure that highlights the firm’s history and accomplishments during the past two decades.

Client Comments

"Mark was retained to handle a complex and sensitive commercial case for one of my clients. The most impressive characteristic of Mark Werbner is his ability to focus on the jury. He views every piece of evidence, every fact, witness mannerisms - everything in terms of what effect it will have on the jury. He breaks down a case to its fundamental elements and makes complicated fact patterns and evidence simple so people seeing and hearing for the first time (be it a judge or a jury) can follow and understand. I know very few lawyers who come close to Mark's ability to sense where the jury is at any moment in a trial and modify his presentation to address. I personally believe this accounts for his trial success rate. Mark is one of the rare lawyers you go to if you have a "Bet The Farm" case."

"Mark Werbner is one of the best trial lawyers in Texas. He's also one of the most respected trial lawyers. He's about as an effective advocate as there is. He is passionate about his client's interests. Mark is about as tough an opponent as any opposing counsel will come across. He presents a case with passion and in a manner that makes it easy for the jury to understand. Mark has successfully defended me in what, for me, was high-stakes litigation, and I am very glad he was my lawyer. I would hire him in the future if I became involved in litigation."

-Steve Leshin

"Mark Werbner strives to do honor to the search for justice and his preparation for trial is unsurpassed. He offers his clients competence, faithfulness, diligence, courtesy, and good judgment while working hard to be worthy of their trust. To opposing parties and their counsel, Mark offers fairness, integrity, courtesy, and civility. The winning record of Mark Werbner is impressive; in my opinion, however, the manner in which he has won all of those cases is more impressive."
