John Quinn represents companies, institutions, and individuals in high-profile civil litigation and leads the firm’s efforts in a number of progressive public interest matters.
John was one of the founders of Kaplan Hecker & Fink in 2017. Since the firm’s launch, John’s civil litigation practice has involved representing Airbnb in obtaining a preliminary injunction under the Fourth Amendment to block implementation of a New York City ordinance that would have required Airbnb to turn over massive amounts of data about its users on a monthly basis, defending Gigi Hadid and Ariana Grande in copyright lawsuits brought by paparazzi, navigating a prominent hotel developer through complex multi-jurisdictional litigation and arbitration proceedings, advising a large hedge fund on multiple matters involving potential litigation, and negotiating a complex settlement to multiple disputes involving a renowned art estate. John also spearheaded the development and filing of a massive RICO case against President Trump and his family and businesses, worked on multiple amicus briefs filed in the United States Supreme Court in cases challenging various executive actions by the Trump administration, and represented a student-led LGBT pride organization in Starkville, Mississippi, in a successful constitutional challenge to the city’s denial of a parade permit—and then flew to Starkville to help lead the parade. John regularly argues in state and federal courts and has extensive experience managing large litigation matters, meeting with government agencies, and advising senior executives of major institutions.
Prior to helping launch Kaplan Hecker & Fink, John spent six years in the litigation group at Sullivan & Cromwell, where his work included representing Microsoft in a multi-billion-dollar jury trial, working with a hedge fund to raise concerns about a global multi-level marketing company, and representing an international financial institution in a criminal investigation into corruption in international soccer broadcasting.
John is a member of Kaplan Hecker & Fink’s diversity and inclusion committee and is heavily involved in the firm’s recruiting, training, and professional development programs. John is proud to serve as a member of the board of the Ali Forney Center, the largest LGBT youth homeless shelter and community center in the country. John has been active in the mentoring of LGBT associates and law students. John also has invested substantial time coaching high school mock trial programs.
John clerked for the Honorable John R. Padova in the United States District Court for the Eastern District of Pennsylvania in his hometown of Philadelphia. He is a magna cum laude graduate of Harvard Law School, where he was awarded the Joseph H. Beale Prize for excellence in Conflict of Laws and the Addison Brown Prize, a prize awarded biannually or annually for an outstanding essay relating to private international law or maritime law. During law school, John served as a Teaching Fellow at Harvard College for a course on constitutional law, assisted Iraqi refugees in need or priority resettlement, collaborated in the development of violence mitigation programs for Sudanese refugee youth in Cairo, and represented clients in criminal proceedings in Roxbury and Dorchester through the Harvard Criminal Justice Institute. John also won a national championship as a member of the Harvard Criminal Justice Institute trial team. John is an Honorary Overseas Member of the Commercial Bar Association of London.
