(he, him, his)


Brian Markley is a trial lawyer trusted by clients with their most challenging issues. His practice primarily focuses on the agriculture, chemical, financial, and retail industries, and he has experience with antitrust, consumer protection, business torts, employment, and other commercial claims. Class actions and multi-district litigation comprise a significant portion of Brian’s practice and he has served in a leadership group of defendants targeted in multi-district litigation.

Clients also rely on Brian to protect their interests when they hire or part ways with executives or key employees. For example, Brian has handled non-compete, non-solicitation, and trade secrets matters arising under the laws of more than 20 states.

Brian has tried a complex commercial litigation case with more than $3 billion at stake. He has also represented midsized companies, family businesses and startups for whom smaller financial stakes, equitable issues or principles are just as significant. Brian approaches each case with the same attention to detail and focused advocacy, always working with each client to obtain the best outcome for the business. After the successful conclusion of one matter, the President / CEO of a client declared, “Brian’s strategy, preparation and courtroom performance carried the day and took the victory. I could not be more pleased with his dedication and expertise.”

In addition to his courtroom experience, Brian serves as a trusted advisor and general counsel for several companies. In that role, Brian is regularly asked to identify, assess, predict and manage legal and business risks. He has developed particular experience in areas of privacy, California Proposition 65, and gaming.

Prior to starting his legal practice, Brian clerked for Judge John W. Lungstrum in the U.S. District Court for the District of Kansas and served on the staff of Senator John C. Danforth.
