Great experience working with Mr. O’Connor! He was friendly, professional, and communicated quickly. He also got me an amazing outcome, which I am very grateful for. Highly, highly recommended. Thank you, O’Connor Law!
I’m incredibly grateful for the help and professionalism I received from Matthew. When I first contacted him, I had been told I was under investigation, and I was extremely stressed and confused. He took my case seriously from day one, kept an eye on the court system, and made sure I was always informed. What started as a serious felony accusation ended with no arrest, no charges, and eventually every charge fully dismissed. He stayed on top of everything and handled my situation with confidence and expertise. I always felt like my case mattered. Thanks to him, I can now move forward with peace of mind. Highly recommend his services to anyone who needs a reliable and dedicated attorney.

Matthew O'Connor is a complete professional. From the initial conversation I knew we were going to receive the very best representation possible. He was thorough in his explanation of all the challenges ahead and what our options were in dealing with them. Matt and his staff were always accessible , throughout the entire process, when we had any questions or concerns. I would highly recommend them to help with all your legal needs.
I’m really grateful for the help I received on my case. Mr. O’Connor was professional, honest, and always kept me updated. He worked hard to get me the best possible outcome, and I’m very satisfied with how everything turned out. I highly recommend him if you’re looking for someone who actually cares and knows what they’re doing.
Mr. O’Connor was a godsend. He was referred to me by the Contra Costa County Bar Association, another excellent resource that was, like Mr. O’Connor, extremely helpful and responsive. Upon hiring Mr. O’Connor, I immediately felt great relief, knowing someone with his experience and expertise was on my side. The latter proved to be so true. Mr. O’Connor was with me every step of the way, never sugar coating any situation but clearly explaining what was going on. Lawyers don’t come cheap, but Mr. O’Connor’s fee was worth every penny in the peace of mind I found knowing someone of his calibre was in my corner. I’d also like to thank his staff, who were excellent, and responded to my every request or concern in a timely manner.
Matt O'Connor was extremely professional. In a unfortunate case, that left me with complete uncertainty, he was able to calm my anxiety with his demeanor, expertise and background. With high stakes hinging on his abilities, he was able to successfully help me in resolving my case. He was extremely accessible to answer any questions or concerns I had throughout the entire process, leaving me at ease and confident that I had the right representative. As far as his rates for service, they were by far the best after consulting with several other law firms. I am so grateful to have had him in my corner and could not thank him enough for the outcome of my case. I would highly recommend consulting with him, you will not regret it. Although I never intend on needing him again, I would not hesitate reaching out in any matter requiring criminal defense. Thank you Matt, Your service will never go unnoticed.
Thank you for the positive review, Siuea. Sincerely, it's my mission here at O'Connor Law to provide each of my clients with the very best representation possible. I'm glad you had a positive experience, and am grateful to have worked with you as well.

Thank you for your positive feedback, Feruz! It was my pleasure to work with you on your case, and I'm thrilled to hear that your experience with our firm was top-notch. Best to you, Matthew O'Connor
Excellent attorney!
Found Matt when my grandson (we've raised him since he was a baby) lost control of our car and drove through a couple's fence hitting the owner. It was a felony charge against a juvenile. Matt handled everything and walked us through every step. We were in the process of moving from Santa Clara County to Sacramento County which added to the complexity. We could not have handled this without Matt's patience and guidance.
Glad to hear that your experience was such a positive one, James. Thanks very much for your kind words. Our firm is very intentional about making our clients top priorities, and I'm pleased to know that the representation you received positively improved the process for you.
Grateful for finding a DUI expert lve never had issues with the law til Nov 2023 Got my first DUI I was clueless what to do I did my research found the best lawyer. He put my mind at ease walked me through it all even recommended where to take my DUI class. Mr O’Conner showed up to all my court hearings, DMV proceedings l did not have to be there. I went to his office signed papers he was good at explaining it all step by step. Always return my calls and emails. Exceptional professional at all times. I highly recommend Mr O’Conner.

Great lawyer upon first consult, whom made the entire experience very manageable & provided accessible information.
To whom it may concern. Mr. O’connor handled my case diligently and thoroughly from start to finish. He was able to help me retain my driver’s license in my state and went out of his way to represent me in Truckee, Ca, from his home in Walnut Creek. I appreciate his professionalism and recommend him to others who value the best outcome of their case.

If you are charged with a DUI you absolutely need legal representation. The problem is, if you don't already know an attorney that's experienced in this area, you're completely lost. You have no way to tell who's really able to handle your situation. That's where I was a few months ago. After talking to several attorneys, I hired Matt. At the time, I still wasn't sure I made the right selection, but he turned out to be absolutely outstanding. Matt has long-term experience in the area, he understands the intricacies of the process, and he knows virtually all of the individuals at DMV and in the Court system who will impact your case. Matt is extraordinarily competent and produced results for me that were amazing. Anyone would be well-served to have him represent their interests. I really couldn't recommend him more highly.
