This review is from a person who hired this attorney.
| Hired Attorney
Very pleased!
I was in a car accident when I was 7-8 months pregnant (fortunetly my baby was fine), a lady passed her red light and hit the car I was in (when it was our green light). I was advised to get an injury attorney. I was lucky to have found John O'Brien. At our consultation I was very impressed with his honesty and his knowledge. Him and his team took care of everything and I had now worries and was very stress free. My biggest concern was what was this going to cost me. Nothing came out of my personal pocket all through the settlement. At the end I was walking out with about $35,000. A lot more than what I was expecting.

John and his team are highly knowledgeable (shout out to Grant Zehnder), approachable, responsive with communication (email and phone), organized (thanks Brenda Marchant), personable (this human touch was important to have as trust was needed to protect current/future healthcare needs caused by the accident) and now successful in helping collect financial compensation for my injuries and accident- related expenses. That being said, I encourage you to schedule a consultation with John O'Brien Assoicates today as they can focus on the negotiations of your motor vehicle accident while you focus 100% on healing and recovery. And let me tell you,that is where all your energy should be because we only have one body for the rest of our lives.

Motorcycle accident
I was riding my motorcycle last summer on a highway when I was struck from behind by a car. My injuries were pretty bad, my leg was fractured in 2 places and I had some broken ribs. I’m glad I turned to Mr. O’Brien for help because he managed to solve my case in a timely, professional manner and obtained compensation for my injuries. I am now back riding and I owe it just to him!

Thank you for your help!
My daughter was injured on a crosswalk when she was returning from school. A driver failed to stop in time and hit my daughter, throwing her on the ground. We were really lucky she did not get run over, but her injuries were still very serious. John O’Brien aggressively fought to obtain compensation for her accident and we got more than we thought in the first place. He is definitely a life saver!

I recommend Mr. O’Brien!
I was injured on a work site 5 months ago and I needed hospitalization for my injuries. I contacted the law firm of John M. O’Brien, looking for help from a lawyer who knows what he is doing. It was a great experience, he was really helpful and knowledgeable and he treated my case with respect. I was back to work after my treatment and I owe it just to him.

Honest, Smart and Effective attorney
I had no idea about the process of a lawsuit. Mr. O’Brien made everything really simple and easy to understand and I think I have asked over 100 questions and he was always available. Whenever I called him he would always get back to me as soon as possible. He was very professional and friendly in the same time with me. I will surely hire Mr. O’Brien again if I will ever need an attorney in the future.

Experienced lawyer
A friend who suffered from an accident in the past hired John to take care of his case and he recommended that I go talk to him too about my car accident. Needless to say, I was very impressed with his patience and willingness to explain everything in detail. I can say that he truly was the man for the job! Mr. O’Brien treated me with respect and helped me file a lawsuit to recover my damages.

Very pleased!
I am very pleased with the service I got from Mr. O’Brien! We treated my case with more professionalism that I thought I could get and my case was settled very fast. I’m really happy about the compensation I got too! Thank you!

Excellent personal injury lawyer
I’ve never met such an extraordinary professional! Mr. O’Brien has plenty of experience and you can definitely feel that. What I liked the most form the beginning was that he was returning my calls. No other lawyer did that before, and it made me feel “Finally, a lawyer that cares about me!” He successfully handled my case, kept me informed every step of the way and if I would need a personal injury lawyer again (I hope it won’t be necessary), there’s no doubt I would have Mr. O’Brien on my speed dial again.

Best lawyer I haver ever had!
Mr. O’Brien and his team helped me and my family a lot when we had a car accident. All that mattered to us is to get our lives to where they were before the accident and he totally understood us and how to deal with our case. They were all very attentive, compassionate and they weren’t bothered by all our questions and insecurities. They took their time and discussed with us, they explained all our options and let us decide. We tried several attorneys before, and they were so eager to convince us and to put pressure on us. With Mr. O Brien, we really felt he understood us and that he gave his best to educate our opinions. We’ve recommended Mr. O Brien to our colleagues and friends, and they all thanked me later on for this.
