Jonathan Marko is one of Michigan’s top trial lawyers and the founding attorney of Marko Law, a Detroit-based firm known for taking on some of the toughest, most high-profile cases in the state. His practice covers personal injury, civil rights, employment, whistleblower, and catastrophic injury litigation—cases where the stakes are high and justice matters most.
Under Jon’s leadership, Marko Law has built a record of results that places him among Michigan’s most accomplished trial attorneys.
These results span catastrophic personal injury, premises liability, employment discrimination, civil rights, insurance disputes, and correctional healthcare litigation. They reflect more than headline numbers. Each verdict represents a client whose life, livelihood, family, or constitutional rights were placed in the hands of a jury—and a legal team willing to take the case all the way.
Among Jon’s most significant recent results is an approximately $896.5 million verdict arising from catastrophic injuries suffered during a vehicle demonstration at Continental’s Auburn Hills test track. The result established a new benchmark for a single-plaintiff verdict in Michigan and demonstrated what can happen when a trial team combines years of investigation, expert testimony, lifetime-care planning, and relentless courtroom preparation. In a related case arising from the same incident, Jon and the trial team also secured a $2.066 million verdict for the victim’s father, establishing the largest bystander claim verdict in Michigan history.
Marko Law also secured a historic $307.6 million federal civil-rights verdict involving the denial of necessary medical care within a correctional setting. The verdict sent a clear message that constitutional protections do not stop at prison walls and that healthcare providers and institutions can be held accountable when systemic failures cause devastating harm.
Jon’s record-setting $76.7 million premises-liability verdict arose from an explosion at a Kroger facility that caused life-altering injuries to a worker. The verdict became the largest premises-liability award in Michigan history and reinforced Jon’s reputation for taking on major corporations when preventable safety failures permanently change a person’s life.
Jon’s fearless approach has earned him national recognition as a Super Lawyer, a Michigan Lawyers Weekly Leader in the Law, and a Trailblazer in both employment and plaintiff law by the National Law Journal. He is also a Fellow of the Michigan State Bar Foundation, , an honor reserved for less than 5% of Michigan attorneys recognizing professional excellence and service to Michigan’s legal community.
