Mr. Harbur's unique background combines representation of clients on some of the most complex civil and white collar matters with his extensive trial and courtroom experience. This combination enables him to expertly handle every stage of litigation, from early strategic decisions through closing argument in front of a jury. Mr. Harbur believes that in order to most effectively represent clients in litigation, even in cases that ultimately settle, the attorney must have a deep understanding of every stage of the case - especially the pressures and unpredictability of trial. Mr. Harbur has tried more than 25 cases to jury verdict and achieved exceptional results in each case.

Mr. Harbur began his career at one of the nation's preeminent law firms-Gibson, Dunn & Crutcher LLP. At Gibson Dunn, he represented clients in both civil and criminal matters. For example, Mr. Harbur represented a major bank in multiple global regulatory and antitrust investigations, requiring him to help manage teams in the U.S., Zurich, London, Singapore and Hong Kong. At the same time, he also represented local Orange County clients in financial, property, contract, and trade secret disputes.

As Mr. Harbur's career progressed, he discovered that few litigation attorneys have meaningful trial experience, which limits their ability to effectively strategize cases in the early stages of litigation. As a result, and in order to develop this critical skill set, he joined the Los Angeles County District Attorney's Office, one of the largest prosecutorial agencies in the world. As a Deputy District Attorney, Mr. Harbur prosecuted numerous fast-paced and high-stakes cases, including business fraud, gang, and murder cases.

In one of Mr. Harbur's most significant cases while at the District Attorney's Office, he prosecuted a man for first-degree murder after he viciously killed the mother of two young children and left her body in an abandoned lot near Long Beach. After a contentious trial involving testimony from eyewitnesses, DNA/forensic experts, LAPD detectives and others, Mr. Harbur delivered closing arguments to the 12-member jury. The jury took just 3 hours to convict the defendant of first-degree murder and a Los Angeles judge sentenced him to life in prison. News coverage of Mr. Harbur's opening statement is available here. A court transcript of Mr. Harbur's closing argument is available here.

In 2018, Mr. Harbur left the District Attorney's Office to join Callahan & Blaine, California's premier litigation firm.
