Daniel Queen is a partner in Mayer Brown’s Los Angeles office, where he focuses on litigation and dispute resolution. Dan has extensive experience litigating cases in federal and state courts at the trial and appellate levels, as well as conducting internal investigations and defending regulatory inquiries.

Dan’s civil litigation practice concentrates on class action defense, including class action suits alleging improper business practices, false and misleading advertising, violations of the Fair Credit Reporting Act and federal securities laws, and wage and hour violations. His litigation practice also focuses on the banking, finance, and real estate industries, where he has represented clients in complex commercial litigations, U.S. and global regulatory investigations, and land use disputes, among other matters. Beyond the litigation context, Dan advises clients on employment matters, revisions to corporate policies, and compliance issues to minimize future risks.

In addition, Dan maintains an active pro bono practice. He has obtained asylum for individuals who were persecuted based on their LGBT status and other protected grounds; he authored an amicus brief cited by New York’s highest court in its decision to extend visitation rights to same-sex partners; and, most recently, he represented a foster mother in the adoption of her foster child.

Before joining Mayer Brown in 2017, Dan spent seven years as a litigation and enforcement associate at another prominent international law firm based in New York. Dan received his J.D. and LL.M. magna cum laude, Order of the Coif, from Duke University School of Law in 2010, and he received a B.A. in Government and International Relations, magna cum laude, from the College of William and Mary in 2005.
