How we compiled this: CrashStory aggregates public Google reviews, Colorado crash records from CDOT and local agencies, and firm-provided profile data. We do not endorse any firm. Review intelligence scores are derived from automated sentiment and theme analysis of public reviews — treat them as one signal among many, not a verdict.

Very professional and efficient attorney office! Thank you to my case manager Angela! She was very attentive and helpful throughout the whole process of my case keeping me updated with everything and answered every question I can possibly have. I definitely recommend this attorney office to all my friends and family! Thank you O'Brien law group!!
I heard of this law office through a friend who used Kerry O’Brien’s office previously and I couldn’t be anymore satisfied. Although it took a while, they worked on my personal injury case and fought to get me the settlement I deserved. Thank you so much for your endless work. - Sunmi D.
I first want to give a big thanks to Attorney Kerry O’Brien. For being my lifeline during my case. I had no idea what to expect during personal injury claim. I was in pain and Kerry and his team made sure I got the assistance I needed every step of the way. I was difficult for them , but they were understanding and patient with me. Neda you are awesome! I know things we’re challenging but you helped me anyhow. I’m thankful for you. Angela , you definitely were so kind and assisted me with my needs from all aspects. Thanks to the other staff and the LOS ANGELES POLICE DEPARTMENT FOR RECOMMENDING! They really do protect and serve the community. With that being said. I high recommend THE LAW OFFICE OF KERRY O’BRIEN AND THE ENTIRE STAFF for your personal injury needs. I trusted them and they didn’t disappoint. I am now able to continue my medical care on my own. Remember things take time and patience is a virtue ! I love you all. Thank you and God bless and I wish you all prosperity and that your law firm grows! Sincerely, Jamarcus Walker.

Super great and on point service. I got into a car accident and within 4-6 months they took care of everything from day one. When most tried to take advantage , this team genuinely cared for me as a client.
