Geoffrey M. Pipoly is a senior associate in Mayer Brown’s Chicago office and a member of the firm’s Litigation & Dispute Resolution practice.  Geoff’s practice includes commercial, environmental, and product-liability litigation.  He has experience assisting clients at every stage of the litigation process, from the drafting of a complaint or answer, to briefing and arguing dispositive motions, to briefing and arguing an appeal.  Geoff has been the primary author of over a dozen briefs in state and federal appellate courts and has assisted in briefing numerous dispositive motions in state and federal trial courts.  

Geoff also dedicates significant time to the firm’s pro bono efforts, principally on matters involving assisting immigrants. In 2017, Geoff was lead counsel in a complex asylum case; he won that case, and his client is now a lawful permanent resident of the United States. For his efforts in the asylum case, Geoff was named a Rising Star by the National Immigrant Justice Center and he received Mayer Brown’s 2018 Pro Bono Associate of the Year award. In 2018 and 2019, Geoff led a team of Mayer Brown attorneys in federal district court in a successful challenge of the U.S. Government’s decision to terminate Temporary Protected Status (“TPS”) for over 50,000 Haitian nationals. That Mayer Brown team obtained a nationwide preliminary injunction in the TPS case despite having only six weeks to prepare for the hearing. The TPS case was Mayer Brown’s 2019 Litigation Pro Bono Matter of the Year. 

Before joining Mayer Brown, Geoff clerked for Judge Richard Allen Griffin of the United States Court of Appeals for the Sixth Circuit. Geoff also spent a year as a judicial clerk on the Michigan Court of Appeals.  Geoff graduated magna cum laude from the University of Minnesota Law School, where he was elected to the Order of the Coif.  In law school, Geoff was a member of the Minnesota Law Review and was a student editor for the journal Constitutional Commentary.
