John W. Halpin

Direct: 414-312-7261


John was a trial attorney at one of the largest civil defense law firms in Wisconsin and an AmLaw 100 firm before joining Laffey, Leitner & Goode. His experience at those firms, which includes his first jury trial win less than two years out of law school and his representation of some of the world’s best-known brands and major manufacturers, has provided him with a depth and variety of experience that truly sets him apart from his peers.

While he has litigated a wide range of commercial disputes over the past decade, the bulk of John’s practice focuses on product liability, transportation, and real estate and construction matters ranging from proper training and quality assurance through eventual trial and appeals.  Although he is most at home in the courtroom, John has a particular interest in helping his clients avoid lawsuits whenever possible by advising on best practices for risk avoidance and mitigation.  He regularly counsels clients about product warnings and instructions, as well as managing accident response and investigation.
