Chicago Office

Justin From concentrates his practice on matters involving systemic insurance fraud and Racketeer Influenced and Corrupt Organizations Act (RICO) claims. He has represented clients at all stages of litigation, and in connection with various forms of alternative dispute resolution and administrative hearings. He has also managed and conducted investigations for clients.

Prior to joining Katten, Justin was an associate at a large corporate law firm and a boutique commercial litigation firm, where he worked on a wide range of complex commercial, government, and employment litigation in federal and state courts, including matters concerning fraudulent transfers, the legality of a variety of business practices, breaches of fiduciary duties, shareholder rights, patent-holder rights, federalism and comity, class certification, and economic issues related to market definition and antitrust injury.

Justin has a background in advanced mathematics, including statistics and mathematical modeling. Prior to law school, he conducted original mathematics research through the National Science Foundation and taught high school mathematics, including AP Statistics, as a Teach For America Amgen Fellow. Justin uses this background to litigate and consult on matters involving statistical models for liability and damages, and other mathematical issues. He has worked closely with statisticians and economists on the development of expert reports, and briefed numerous Daubert motions.

While in law school, Justin served as an editor on the Executive Board of the Iowa Law Review, the captain of Iowa's National Moot Court Team and a judicial extern to the Honorable Robert W. Pratt of the US District Court for the Southern District of Iowa. He won Iowa's Van Oosterhout–Baskerville Moot Court Competition and attended law school on a full-tuition merit scholarship.
