Jason Marker — Attorney Profile
Jason Marker is a personal injury and workers’ compensation attorney who has practiced in the Chicagoland area for over 25 years. Born and raised in Naperville, he founded Marker Law with the conviction that hardworking people deserve an advocate who understands both sides of injury litigation.
Marker began his career clerking in the City of Chicago’s Torts Division and training under mentor Jack R. Davis. After three years on the defense side, he transitioned to representing injured victims exclusively. That background gives him a unique understanding of how employers and insurance carriers think — and how to counter their tactics.
I learned their playbook. I quickly changed paths to represent injured victims, my true passion, which I have been doing ever since.— Jason Marker, Attorney
