You're in good hands with The O'Brien Firm!
I was a passenger who was injured in a car accident. I had a severe hip fracture that required surgery. Sidney came to my house to see me when I first came home from the hospital. She and her firm were very hands on. She understood that I was just coming out of surgery and could not come into the office. Sidney settled my case in 60 days for the full value of the insurance policy without having to go to court. I was able to focus on getting better while Sidney handled everything regarding my case. She kept in touch with me, gave me feedback about how my case was progressing, and was always straight forward with me. Sidney and The O'Brien Firm worked hard to get me the best possible settlement as fast as possible. I would definitely recommend Sidney and The O'Brien Firm to anyone in need of help.

A direct and thorough lawyer!
Sidney is an awesome lawyer with great communication skills. Staying in contact with me throughout the whole process of my case, she filled me in with me on details of law, I wasn't familiar with. She knew exactly who to call, kept me informed, and sought the best settlement for me. I am very pleased with the results of my case. I'd definitely recommend her!

A Great Lawyer!
It was a pleasure working with Sidney. She has tremendous litigation skills and fought for a fair settlement in my case. I am very pleased with the end result. Sidney fought to get me the largest settlement possible. She kept me informed on every aspect of my case and was available via phone or face to face at any time I requested. I greatly appreciate Sidney. She is a great asset to The O'Brien Firm.
