John Quinn is a Partner at Kaplan Hecker & Fink.  John was selected by Super Lawyers as a 2018 New York Rising Star in Business Litigation, and was recently named one of the Best LGBT Lawyers Under 40 by the National LGBT Bar Association. John joined Kaplan Hecker & Fink from Sullivan & Cromwell, where he spent six years in the Litigation Group. He is a litigator with a wide-ranging practice that includes areas such as antitrust, active-short selling, consumer protection, money laundering and racketeering, and general commercial litigation. John has extensive experience representing clients in court proceedings, taking and defending depositions, advising senior executives of major institutions, managing large litigation teams, and meeting with government agencies.

“I am passionate about finding solutions in the law that are sensible and sustainable. I relish the intellectual sport of thinking through an issue comprehensively, developing a clear strategy, and engaging in advocacy at the highest levels against smart opponents.”

John led the team at Kaplan Hecker & Fink that successfully represented a large hotel developer in complex and fast-paced contract dispute, including proceedings in multiple forums.  John also managed the firm’s representation of Starkville Pride, a student-led LGBT pride organization in Starkville, Mississippi, in a successful constitutional challenge to the city’s denial of a permit for a pride parade.  John also has represented a non-profit regional healthcare provider in its appeal of a post-trial damages ruling, as well as an individual appealing an unfavorable standing determination in a high-profile custody case. John also represents a large tech company in several cases in New York, and has assisted in advising a large media company conducting an internal review of policies, procedures, and practices relating to gender issues.  John also has advised the principals of multiple large estates in significant and time-sensitive disputes. In addition, John has worked on petitions for a writ of certiorari submitted to the U.S. Supreme Court, as well as other substantial submissions in pro bono and public interest cases.

Early in his career, John was part of the trial team defending a multinational technology company in an eight-week, multi-billion dollar antitrust trial, which ended with a hung jury, entry of judgment in the company’s favor, a unanimous affirmance on appeal, and the denial of a petition for a writ of certiorari to the U.S. Supreme Court. John also contributed to important victories for a multinational finance company, an automobile manufacturer, and a number of other clients. In addition, John worked closely with the Senior Chairman of the Firm and the co-head of the Firm’s Corporate Group on a major civil litigation involving claims brought against the Federal Government. John also spent several years representing a hedge fund management company in its effort to investigate and raise concerns about a global multi-level marketing company. Most recently, John represented an international financial institution in connection with a criminal investigation into corruption in international soccer broadcasting.

John is heavily involved in Kaplan Hecker & Fink’s recruiting, training, and professional development programs.  John also has been active in the mentoring of LGBT associates and law students, and has traveled to events and panel discussions to talk with law students about navigating the interview process and firm life as an LGBT student and lawyer. He has served as a Teaching Fellow at Harvard College for a course on constitutional law, and– in addition to securing wins himself as a National Trial Team Competitor– has invested significant time and energy in mentoring and coaching high school mock trial teams. John also has dedicated his efforts to public interest lawyering:  helping to develop public interest cases at Kaplan Hecker & Fink, assisting Iraqi refugees in need of priority resettlement in Egypt, collaborating in the development of violence mitigation programs for Sudanese refugee gang youth, and representing clients in criminal proceedings in Roxbury and Dorchester through the Harvard Criminal Justice Institute.
