What Tomasik Kotin Kasserman, LLC does

Tomasik Kotin Kasserman, LLC (TKK Law) is a Chicago-based plaintiff-side personal injury law firm founded in 2013 by Timothy Tomasik, Daniel M. Kotin, and Shawn Kasserman. The firm represents individual injury victims and bereaved families across practice areas including personal injury (auto, trucking, motorcycle, bicycle, pedestrian, boating, construction negligence, premises liability, mass transportation, aviation, rideshare, nursing home abuse, product liability, food poisoning, catastrophic injuries, sexual abuse, and toxic tort), medical negligence (birth injuries, anesthesia, misdiagnosis, surgical errors), and wrongful death. It also operates a referring-lawyer program for co-counsel engagements and a Spanish-language practice line for Hispanic clients. The roster comprises roughly 12 attorneys plus support staff, with stated combined experience exceeding 150 years and admissions to the American College of Trial Lawyers and American Board of Trial Advocates.

The firm's business model is contingency-fee representation: clients pay nothing upfront and owe no fees unless the firm secures compensation, with the firm earning a percentage of any settlement or verdict. The firm has obtained hundreds of millions of dollars in cumulative verdicts and settlements, including headline results such as a $1.2 billion World Trade Center settlement (lead counsel role), a $29.6 million Illinois record train-accident verdict, a $30.2 million medical malpractice verdict, and a $25.9 million taxi accident verdict. No proprietary technology platform is disclosed; service delivery rests on attorney expertise, courtroom experience, and trial advocacy rather than software.

Go-to-market is direct-to-consumer, driven by SEO-optimized website content, a blog active since 2013, social media (LinkedIn, Facebook, Twitter/X, Instagram, YouTube), earned media (Wall Street Journal, Chicago Tribune, Crain's, CBS News), speaking engagements at bar associations and trial-lawyer conferences, a law-student scholarship program, and a referring-lawyer channel. The firm operates from a single Chicago headquarters at 161 North Clark Street, Suite 3050, and accepts inquiries via phone (312-605-8800), web forms, email, and walk-in consultations. Revenue is not publicly disclosed, and the firm is privately held by its partners with no outside investment.
