Michael J. Quirk concentrates on consumer protection and class action litigation in addition to working on employment, civil rights, and products liability cases. He has extensive experience fighting against enforcement of overreaching mandatory arbitration clauses that are used by companies to strip consumers and workers of their constitutional right to a jury trial.

Born and raised in Englishtown, New Jersey, Quirk graduated cum laude from the University of Michigan Law School in 1999. He received his bachelor's degree in history from The College of New Jersey and a master's degree in American history from the Rutgers University-Newark Graduate School. Before joining Williams Cuker Berezofsky, Quirk was an Equal Justice Works Fellow and then a Staff Attorney with Trial Lawyers for Public Justice (now "Public Justice") in Washington, DC. He was previously a Supreme Court Assistance Project Fellow with the Public Citizen Litigation Group, also in Washington, DC.

Quirk has litigated appeals on behalf of consumers regarding mandatory arbitration and class action issues in federal and state courts throughout the country. He is co-author of the first five editions of Consumer Arbitration Agreements: Enforceability and Other Topics (National Consumer Law Center and The Public Justice Foundation), published as part of NCLC's Consumer Credit and Sales Legal Practice Series. He also has written numerous articles and lectured frequently on consumer rights and access to justice issues.
