As a partner at Bartlit Beck Herman Palenchar & Scott LLP in Chicago, Mr. Gallagher’s accomplishments in court have earned him numerous recognitions including as a National Litigation Star by Benchmark Litigation.​

Mr. Gallagher graduated from the University of Michigan in 1991 and, with his sights set on a career in law, enrolled at the university’s law school. He received his Juris Doctor, magna cum laude, in 1994 and began serving as a law clerk at the U.S. Court of Appeals for the Ninth Circuit, followed by a clerkship for Justice Sandra Day O’Connor of the U.S. Supreme Court. In 1996, an opportunity to work for a nationally recognized litigation firm brought Mr. Gallagher to Chicago.

At Bartlit Beck Herman Palenchar & Scott LLP, Mr. Gallagher represents major U.S. and international companies in complex commercial litigation cases involving everything from intellectual property to breach of contract. A seasoned trial attorney, he focuses his energy on developing themes and gathering evidence that will carry weight in court, and uses innovative technology to communicate complex concepts to juries. With this trademark preparedness, Mr. Gallagher is ready to take on a case at any stage of litigation and provides clients with a considerable advantage at the settlement table as well.

A clear leader in his field, Mr. Gallagher keeps his eye on prevailing developments in commercial litigation. In particular, he has noticed a shift in how companies pay their outside counsel. He noted:

In the past, our competitors typically billed by the hour, causing a lot of unnecessary costs for their clients. We have always had a different approach: we set up  a fee -based arrangement that keeps us focused on results. Now, fees are becoming much more common, especially on the defense side, and clients are starting to demand this structure more and more.

After more than two decades dedicated to litigation, Mr. Gallagher has no intention of resting on his laurels. Moving forward, he hopes to continue developing his expertise by trying more cases and envisions a bright future ahead for himself and his clients.
