What Clients Are Saying

  • “Mr. Brennan showed up and showed out for my case. Even with being given my case halfway through the process because my original lawyer retired he never treated me or the process of my case with half the energy or persistence. He was also thorough with explaining every process and the steps as we went along. I could always count on his frequent contact and updates and he never sold me a dream. I appreciated his honesty and tenacity and in the end was able to win me a judgment that was fair and one I was satisfied with after fighting the case since 2017, even against all odds. Outside of his professional qualities…..he is so very funny, personable and kind. He sees you as a human being and treats you with compassion. An absolute classy and overall great man! I am so proud he represented me. If you need assistance with your injury case you can trust he will go above and beyond for you. Mr. Brennan THANK YOU FOR EVERYTHING!!!! God bless you!”

  • “In May of 2022, as I was at a red light behind two other cars waiting to make a left turn, my SUV was forcefully rear-ended, resulting in my SUV being totaled. I sustained a herniated disc in my cervical spine as a result of the impact. Thankfully, I called personal injury attorney, Michael Brennan, because he is very professional and sharp! His paralegal assistant, Laura, is also very knowledgeable and helpful. I never felt alone during the long legal journey, and I highly recommend Mike Brennan. I am very grateful for the long hours that he and Laura put into my case. Top notch personal injury attorney in Orland Park!”

  • “I used Attorney Brennan to represent a family member in a non-vehicle related accident that resulted in serious injury. Unfortunately, the case lacked video evidence and witnesses making a legitimate personal injury case difficult to present. Along the way, Mike and his assistant Laura worked closely with me to obtain compensation for my family members injuries. MJB was able to secure a reasonable amount of compensation for a difficult case. The result greatly helped with continued medical expenses. Very much appreciated. Thanks to Mike and Laura.”

  • “I can’t say enough wonderful things about Michael Brennan. We went to him after dumping a previous council because he was going to tell me to plead guilty. Mr. Brennan said “You don’t have to hire me, but DO NOT PLEA” we took his advice and did in fact hire him. Thank god we did because he handled my case and got me the outcome I knew I deserved . I haven’t met any lawyer more professional than him. Thank you again”

Frequently Asked Questions

Illinois allows personal injury victims up to two years to file claims. You shouldn’t wait years to file though. Take action quickly to allow your lawyer to capture fresh evidence and keep track of witnesses.

Not usually. Most personal injury cases are resolved through negotiations resulting in an accident settlement. Insurance companies do their best to avoid the costs of going to trial and the embarrassment.

Michael J. Brennan works on a contingency basis. It means you won’t owe anything unless he wins your case for you. Then his attorney fee comes out of the settlement money you and your family are awarded.
