He founded Cogdell Law Firm and has represented clients in state and federal proceedings across the United States. His career has included prominent cases involving the Branch Davidian trial, Enron, securities-fraud allegations, and the 2023 impeachment proceedings involving Texas Attorney General Ken Paxton.
His professional profile has also received substantial attention from legal publications and media organizations. As of 2026, Dan Cogdell remains active in legal practice while continuing to be associated with some of the most widely discussed courtroom matters of his career.
Who Is Dan Cogdell?
Dan Lamar Cogdell is a Texas attorney and the founder of Cogdell Law Firm in Houston. The State Bar of Texas lists him as eligible to practice in Texas and identifies his practice areas as criminal law, environmental law, and securities law. His Texas license dates to November 5, 1982.
Cogdell’s professional work extends beyond Texas state courts. His listed federal admissions include the U.S. Supreme Court, U.S. Court of Appeals for the Fifth Circuit, and multiple federal district courts. His career has therefore involved both state and federal litigation.
The U.S. District Court for the Southern District of Texas describes Cogdell as having tried hundreds of cases in numerous states and notes his work representing public officials, business executives, physicians, law-enforcement personnel, and other clients. The court’s biography also states that his present practice focuses on white-collar criminal defense, federal criminal defense, criminal appeals, grand-jury investigations, and fraud cases.
Dan Cogdell Education and Early Legal Career
Cogdell’s educational background includes a B.B.A. from the University of Texas at Austin, which he earned in 1979. He subsequently earned his Juris Doctor with highest honors from South Texas College of Law, graduating in 1982.
After law school, Cogdell worked as a briefing attorney for Presiding Judge John F. Onion Jr. of the Texas Court of Criminal Appeals. This early experience gave him exposure to appellate criminal law before he moved into private practice.
He later worked with legendary Texas criminal-defense lawyer Richard “Racehorse” Haynes at Haynes & Fullenweider. According to the Southern District of Texas biography, Cogdell became the youngest partner in that firm’s history before leaving in 1988 to establish his own practice.
That foundation helped shape the courtroom-focused practice for which Cogdell subsequently became known. His work has involved cases ranging from complex financial allegations to major criminal prosecutions.
Dan Cogdell and the Branch Davidian Trial
One of the most recognizable chapters of Dan Cogdell’s legal career is his involvement in the Branch Davidian trial arising from the 1993 Waco siege.
Cogdell represented Clive Doyle, a Branch Davidian member who faced federal charges following the events at the group’s compound near Waco, Texas. The Southern District of Texas states that Cogdell’s courtroom work in the case later became the subject of documentary and dramatic productions.
The case has continued to attract public attention decades after the original events. Cogdell’s role was later dramatized in the Paramount series Waco: The Aftermath, where actor Giovanni Ribisi portrayed Cogdell. The Southern District of Texas specifically notes the connection between Cogdell’s courtroom work and the later television production.
This case became one of the defining examples of how Cogdell’s courtroom career crossed into broader popular culture.
Dan Cogdell and the Enron Case
Another major case associated with Dan Cogdell is the Enron scandal, one of the most consequential corporate-fraud episodes in modern U.S. history.
According to profiles published by Best Lawyers and the Southern District of Texas, Cogdell represented an Enron-related defendant and obtained an acquittal, which those sources describe as the only acquittal in an Enron-related criminal matter.
The Enron case illustrates the type of complicated litigation that has become central to Cogdell’s professional profile. Such cases can involve extensive financial records, corporate transactions, federal investigations, expert testimony, and complicated questions concerning individual responsibility.
His work in the Enron matter subsequently became part of the broader media and legal coverage surrounding his career.
Dan Cogdell and the Ken Paxton Impeachment
A more recent high-profile chapter involved Texas Attorney General Ken Paxton.
Cogdell represented Paxton during the attorney general’s 2023 impeachment trial before the Texas Senate. The Southern District of Texas states that Cogdell successfully defended Paxton against the impeachment articles brought before the Texas Senate.
Cogdell had also represented Paxton in a long-running state securities-fraud case. In 2023, the securities-fraud charges were dismissed after a resolution that ended the prosecution, according to reporting and legal profiles.
The Paxton representation also became relevant to Texas politics in 2026. In June 2026, The Texas Tribune reported that Cogdell publicly endorsed James Talarico in the Texas U.S. Senate race after previously representing Paxton. The report attributed Cogdell’s comments and described his relationship with Paxton as spanning nearly a decade of legal representation.

Cogdell’s professional work includes white-collar criminal defense, federal criminal defense, securities matters, fraud cases, criminal appeals, and government investigations. His firm’s current website also lists complex civil litigation and other high-stakes matters among its practice areas.
His professional recognition includes membership as a Fellow of the American College of Trial Lawyers. The Southern District of Texas notes that fellowship is limited to a small percentage of lawyers in the United States.
Chambers currently lists Cogdell in its 2026 USA guide for Litigation: White-Collar Crime & Government Investigations in Texas, with a Band 1 designation. Best Lawyers also lists him in criminal-defense practice areas and states that he has been recognized by the publication since the 1990s.
The State Bar of Texas profile provides another useful professional reference point: it lists his Houston practice location and confirms that there is no public disciplinary history reported on the Texas attorney profile.
