Michael J. Brennan

40+ Years of Effective Personal Injury Law

Proudly Serving Clients in Orland Park + the Chicagoland area

Attorney Michael J. Brennan has been fighting for injury victims and their families in Illinois for nearly four decades. Since 1985, he has built a legal career rooted in trial experience, client-focused service, and a strong commitment to results. He opened the Law Offices of Michael J. Brennan in 1995 to provide individuals in Cook County and across the southwest suburbs with direct, one-on-one legal representation after life-changing injuries.

Today, Michael focuses exclusively on personal injury and wrongful death cases — including car accidents, nursing home abuse, medical malpractice, and catastrophic injury claims. He represents individuals and families in Orland Park, Tinley Park, Oak Lawn, Palos Heights, and throughout the Chicagoland area.

At his firm, every case is personally handled by Michael from beginning to end. Clients never get passed off to a junior associate or case manager. That level of personal involvement makes a difference — and it’s one of the reasons why Michael has earned the trust of clients throughout the region.

Michael J. Brennan: Background + Experience

Before founding his own practice, Michael served as an Assistant State’s Attorney for Cook County, where he prosecuted criminal cases and built a deep understanding of courtroom dynamics, evidence, and cross-examination. That early trial experience continues to serve his clients today, especially when personal injury cases move from the negotiation table into the courtroom.

Michael uses that prosecutorial insight to anticipate the strategies used by insurance companies and defense counsel. He is a skilled negotiator, but never hesitates to take a case to trial if that’s what’s required to pursue full and fair compensation.

Whether you’re recovering from a serious injury or dealing with the loss of a loved one, Michael will take the time to listen, investigate your case thoroughly, and guide you through every step of the legal process.

A Personal Approach to Every Case

Michael understands that reaching out to a lawyer usually follows a crisis — an accident, a traumatic injury, or the loss of a family member. He believes you deserve to work with someone who sees you as a person, not a case number.

At his firm, you’ll never be passed around or left wondering who’s handling your claim. Michael will be your point of contact — the person who answers your questions, makes the calls, and represents you in court.

If you’re looking for a local personal injury lawyer who combines experience, integrity, and personal attention, you’re in the right place.
