Mazie Slater Katz & Freeman

What Mazie Slater Katz & Freeman does

Mazie Slater Katz & Freeman LLC is a privately held New Jersey plaintiff-side litigation firm headquartered in Roseland, organized as an LLC with 11–50 employees. The firm provides legal representation to seriously injured individuals in personal injury, medical malpractice, car accidents, burn injuries, spinal cord injuries, wrongful death, product liability, defective medical devices, class actions, commercial litigation, whistleblower claims, professional liability, legal malpractice, and sexual abuse matters. Its core offering is contingency-fee plaintiff litigation rather than a technology product: the firm finances cases against well-resourced defendants (corporations, hospitals, insurance carriers, and government entities) and earns a percentage of recovered verdicts and settlements, with no fees charged unless it wins. No underlying technology platform is disclosed; acquisition relies on phone intake (973.228.9898), website contact, free consultations, attorney media appearances on national broadcast outlets, and word-of-mouth referrals.

The firm has built a track record that includes the two largest jury verdicts in New Jersey history ($166M against the State of New Jersey; $135M alcohol liability verdict), the largest single personal injury settlement in NJ history ($125M utility-pole case), and over $1 billion in aggregate client recoveries. It has been named one of the Top 50 Plaintiff Law Firms in the country by the National Law Journal, placed on the Plaintiffs Hot List, recognized as Personal Injury Litigation Department of the Year and Medical Malpractice Law Firm of the Year (United States) by the National Law Journal / NJ Law Journal, and included in the U.S. News & World Report Best Law Firms top tier. Lead partners David A. Mazie and Adam M. Slater have been inducted into the NJ Law Journal Personal Injury Hall of Fame, and the firm is built around NJ Supreme Court certified Civil Trial Attorneys and Super Lawyers/Best Lawyers-recognized attorneys.

The revenue model is a single stream: contingency fees on settlements and verdicts. Acquisition channels are sales-led, with distribution limited to direct client intake via phone, website, and free consultation. The firm markets itself as trial-ready and willing to litigate rather than settle for less, and its case portfolio is concentrated in New Jersey with class action and media coverage extending national reach. Operating geography is the United States (Northeast, with national plaintiff-side case selection), with no disclosed offices outside Roseland, no funding rounds, and no parent company or institutional investment.
