John McCarthy
Wisconsin’s Motorcycle Accident and Wrongful Death Lawyer
John McCarthy is a Wisconsin motorcycle accident and wrongful death lawyer whose practice is built around representing injured riders and families after fatal motorcycle crashes. Motorcycle cases are not a subset of his work. They are the core of his practice.
In limited cases, he also represents other vulnerable road users when those cases involve the same risks, biases, and investigative challenges motorcyclists face.
A Practice Focused on Riders
John McCarthy focuses almost exclusively on Wisconsin motorcycle accident and wrongful death cases. He represents riders and families throughout Wisconsin in serious injury and fatal crash cases involving left turn collisions, failure to yield, distracted and impaired drivers, commercial vehicles, and cases that require early, aggressive investigation to counter rider bias.
There are many lawyers who say they “handle” motorcycle cases. John has built his entire practice around them.
Why Motorcycle Cases Are Personal
Before he ever stepped into a courtroom, John was a rider. Grease under his fingernails. Sweat and dust on his face. A deep love for motorcycles in his bones. For years, he pictured retirement as simple and quiet, an old Triumph and an open stretch of road.
That changed when one of his closest friends and mentors was killed in a motorcycle accident.
At the same time John and his wife were talking about starting a family, he was helping his friend’s widow shut down his law practice. The experience hit hard. He could not imagine placing that burden on his own family if something happened to him.
That’s when John walked away from riding for good.
But he never walked away from riders.
He understands the risks every motorcyclist accepts when they swing a leg over a bike. He understands how quickly life can change. And he understands how unfair the legal system can be when a rider is injured or killed and blame shifts before the facts are even known.
That understanding shapes how he practices law, It’s how he became a nationally known motorcycle accident lawyer.
Willing to Take Hard Cases
John met Clay Griessmeyer in law school. Both grew up in small towns. Both rode. Both believed the law should protect people, not shield corporations.
Together, they have handled serious motorcycle injury and wrongful death cases and have been willing to take difficult cases to trial when others declined. They handle every case like it’s going to trial. They prepare cases thoroughly, investigate early, and do not shy away from hard fights.
