Mark Trachtenberg

Recognized as one of the top 100 lawyers in Texas and as one of the top appellate lawyers in the state by Texas Super Lawyers (Thomson Reuters), Mark Trachtenberg represents major companies in high-stakes appeals. He is ranked in Chambers USA, 2019-2021 (Chambers and Partners) for appellate law in Texas, which notes his “excellent ability to see the broad picture and evaluate appellate issues before they even arise at the trial stage” and describes him as “very responsive, a superlative writer, and a good ideas person.”

Mark’s accomplishments for clients include:

  • Obtaining reversal in the Texas Supreme Court of a $22 million tortious interference and trade secret misappropriation judgment
  • Obtaining a summary judgment in a False Claims Act case in which the plaintiffs had sought billions in damages against a major oil company, and successfully defending the appeal of the take-nothing judgment in the Fifth Circuit
  • Successfully defending a Fifth Circuit appeal of a $3.6 billion bankruptcy plan of reorganization
  • Obtaining a reversal in the Texas Supreme Court of a $14 million products liability judgment
  • Prevailing on a special appearance that shielded the firm’s Singaporean client from a potential $500 million judgment

A highlight of Mark’s career has been his work on behalf of Texas public schools, an opportunity that arose from a law review article he authored on the history of Texas’s school finance litigation while at Yale Law School. Mark played a lead role in a lawsuit that resulted in an infusion of more than $2 billion for public schools in Texas. He later served as lead counsel at trial and on appeal for a coalition of 88 school districts in a second lawsuit challenging the constitutionality of the state’s school finance system.

Mark is a member of the American Law Institute, recently served as the chair of the Houston Bar Association’s Appellate Practice Section, and is on the board of directors of the Texas Supreme Court Historical Society. Mark is also dedicated to his community, serving as the chair of the Southwest Region of the Anti-Defamation League and on the Education Policy Committee of the United Way of Greater Houston.

Mark writes and speaks prolifically on a variety of topics, with a recent focus on arbitration issues, brief writing, and Fifth Circuit and Texas Supreme Court trends. He is board certified in civil appellate law by the Texas Board of Legal Specialization.
