Joel Mitnick brings over four decades of Big Law and government Antitrust experience to the Law Offices of Joel M Mitnick, which he founded in April 2024. Joel has spent a career advising clients on the most difficult antitrust issues and in guiding parties and investors through the government thicket of merger filings, review and clearance. Joel’s boutique antitrust practice allows for hands-on, client focused attention without large law firm administrative distractions. Simply put, Joel brings the quality clients demand of a large law firm partner at the price and with the attention they would expect of a small firm.
Joel's practice focuses on antitrust matters on behalf of a wide array of financial market, life science, media, service industry and industrial clients. Joel represents clients in Federal and State antitrust investigations, antitrust class actions and merger clearance proceedings. He has tried merger cases to verdict and briefed antitrust class actions up to the United States Supreme Court. Joel also counsels some of the nation’s most prominent activist and passive hedge funds in terms of share accumulation and HSR filing strategies, board representation and antitrust/HSR compliance training.
Joel began his career as a Trial Lawyer at the Federal Trade Commission litigating cases to enjoin proposed mergers. He most recently led the transactional antitrust practice at Cadwalader, Wickersham & Taft, served earlier as the longtime Global Co-Head of Antitrust at Sidley Austin, and trained as an Antitrust Group associate at Skadden, Arps, Slate, Meagher & Flom.
Joel appears regularly before federal and state antitrust enforcement agencies. A frequent speaker and author, he has lectured at enforcement programs sponsored by the Federal Trade Commission and the National Association of Attorneys General, and has served as an ABA Antitrust Trial Skills faculty member. Most recently, Joel spoke on a panel about proposed Hart-Scott-Rodino rules hosted by the NYU Law Institute for Corporate Governance & Finance, and was featured at investment bank programs on antitrust developments in the technology industry and on the antitrust risk of ESG investments.
Joel earned his J.D. from American University, Washington College of Law, and his B.A., magna cum laude, from Washington University in St. Louis (honors in economics). He is a member of the bars of the District of Columbia and New York State, and is admitted to practice before the Eastern and Southern Districts of New York, and the U.S. Supreme Court.
