Matthew Marcin
Attorney
Matthew Marcin brings a steadfast dedication to justice and a proven record of advocacy for those harmed by powerful corporate interests. In joining Aylstock Witkin Kreis Overholtz in 2026, Matthew continues to build on a distinguished foundation in complex mass tort litigation, with work that has brought him to the front of some of the most consequential litigations in the country.
Before joining the firm, Matthew honed his skills across a broad spectrum of litigations, including the Aqueous Film-Forming Foam (AFFF) Products Liability Litigation (MDL No. 2973), Insulin Pricing Litigation (MDL No. 3080), Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs) Products Liability Litigation (Ozempic) (MDL No. 3094), and Tepezza Marketing, Sales Practices, and Products Liability Litigation (MDL No. 3079). Each matter deepened his understanding of the human toll that corporate misconduct can inflict and reinforced his commitment to holding wrongdoers accountable.
Matthew currently serves in a leadership capacity as a member of the Plaintiffs’ Executive Committees for Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAS) Products Liability Litigation (Ozempic) (MDL No. 3094) and Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs) Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) (MDL No. 3163) before the U.S. District Court for the Eastern District of Pennsylvania. Aside from his leadership positions, Matthew’s MDL practice also includes Roblox Corporation Child Sexual Exploitation and Assault Litigation (MDL No. 3166) before the U.S. District Court for the Northern District of California, as well as the Insulin Pricing Litigation (MDL No. 3080) before the U.S. District Court for the District of New Jersey.
Beyond his involvement with consolidated multi-district litigations, Matthew is at the forefront of emerging theories of liability, pursuing Video Game Addiction claims against industry giants Microsoft, Mojang, Epic Games, and Roblox, and Gambling App Addiction claims against DraftKings and FanDuel. He also plays an active role in the firm’s mass arbitration practice, representing individuals in corporate data breach and consumer privacy matters.
Matthew’s contributions to the legal profession have not gone unnoticed. He was named an Inweekly Rising Star in 2025 and recognized by the National Trial Lawyers as a Civil Plaintiff Top 40 Under 40 Trial Lawyer in Florida.
Beyond litigation, Matthew is driven by a deep sense of community. He proudly serves on the Rally Foundation Gulf Coast Leadership Board, supporting efforts to advance pediatric cancer research and provide meaningful assistance to families navigating the unimaginable challenges of a pediatric oncology diagnosis. For Matthew, this work is not separate from his legal mission; it is an extension of the same belief that people deserve advocates who will show up for them when it matters most.
Matthew earned his Bachelor of Science in Economics from the University of Michigan and his Juris Doctor from the University of Wisconsin Law School.
When he steps away from his work, Matthew cherishes the time he spends with his wife and daughter. Whether going on family walks, training Brazilian jiu-jitsu, or cheering on the Michigan Wolverines.
