Michael J. Brennan is a personal injury attorney with decades of experience assisting victims of personal injury in Illinois at his two Cook County offices located in Orland Park and Chicago.

Our Cook County personal injury law firm is dedicated to the representation of persons who have been injured by the negligence of others. Those injuries could occur in a number of ways. For instance, Michael J. Brennan offers personal injury law services that help victims of personal injury who have suffered injuries in auto accidents across Illinois recover compensation for their injuries.


Traffic accidents are another major source of injuries in the Illinois region every year. When you’re been injured in a truck accident, it becomes even more complicated to file a claim, because you are filing a claim against a commercial entity.

Several people are injured in motorcycle accidents every year, and these injuries are often catastrophic. Your personal injury claim must recover compensation that will cover all of your injuries and other expenses.

Work-related injuries can happen in any job, and no employment industry is immune from accidents. Because of this, Michael has established himself as one of the best workers compensation lawyers in Illinois.

Pedestrian accidents can cause serious harm because a pedestrian is typically poorly protected against injuries in an accident.

Michael J. Brennan also represents families of persons who have been killed as a result of the negligence of others in wrongful death claims.

He also helps victims of slip and fall accidents who have been injured as a result of negligence by property owners, helping them recover compensation for their losses.

Apart from these cases, our personal injury firm also represents victims of dog attacks who have suffered severe mental and physical trauma in dog bites.

We will work to help you recover the compensation that you are eligible for by using negotiation strategies, and get the best possible outcome for you. However, if the best possible outcome is not possible through negotiations alone, Michael will not hesitate to take your case to court.

The Law Offices of Michael J. Brennan handle personal injury cases in the Cook County and across Illinois cities such as Orland Park.

We pride ourselves on offering our clients a high level of service and dedication. At our firm, your case is not just handed over to an associate lawyer. Instead, Michael will take a personal interest in your case, and will resolve your concerns. Contact our law firm today.
