Best Lawyer to Hire
Mr. O’Connor upon first call consultation provided direct and comprehensive information regarding my fathers case. He was easy to reach and always returned the calls in a timely matter. Recommend 10/10 if you want a lawyer who is attentive to your case, works fast & provides information during the steps of the process.

OUTSTANDING
Matt O'Connor is an outstanding attorney. I used his services several months ago after being charged with a DUI. I had absolutely no experience with the process or any understanding of what difficulties I was facing. I also had no idea which attorney was best suited to deal with my situation, but I got lucky. Who you select to represent you is one of the most important decisions you will make. It can have a huge impact on the outcome of your case. Having Matt represent me and guide me through the process was one of the best things I did. He understands the system and, importantly, the details within the system that can affect you. He not only has long-term experience dealing with this type of case, he also knows the individuals at DMV and in the Court that will impact how your matter is ultimately resolved. I can't recommend Matt more highly. He produced amazing results.

Excellent Attorney
We hired Matt back in 2014 for a DUI for my husband. He has had priors also, Matt was able to get him little to no time then because of prior experience with be a DA he got him a good deal then! Fast forward 6 years my husband found himself In trouble with two cases from two different counties. With Matt’s patience and understanding he explained to us what time my husband was looking at. Thankfully Matt was able to get my husband concurrent time for both so he won’t have to serve much time. It could have been much worse. Thank you Matt. I would recommend him to anyone in need of an attorney.

Hire Matt as your Lawyer!
Matt did an amazing job helping to resolve our case, he was always available to answer any questions we had and did it professionally. He was able to explain what was happening throughout the case in a way that was very understandable. I would absolutely recommend him as a lawyer to anyone that may need one. Thanks Matt!

Top Notch!
I needed representation for a DUI and was referred to Matt O'Connor. Under Mr. O'Connor's guidance, the DMV did not suspend my license and the DA dropped the charge. Matt O'Connor knows how to navigate the ins and outs of the legal system and provided me with excellent representation. He looks for the "wrinkles" and knows to use those in your defense, which is exactly what he did for me. He connected me with the right expert to evaluate my situation and then, with those favorable results, made it sensible to the DA that it was not worth the court's time to pursue charges. I heartily recommend Matt O'Connor as your criminal defense attorney for any matter you may require.

The Best Defense Lawyer!!!
Matt was great in helping me get through the process and eventually got my case dismissed! Because he had prior experience being a prosecutor, that he knew how to defend clients, and that is why I hired him. If you need legal representation, Matt is your attorney!! Thank you Matt for all your help!

Dui Defense
Matt O’Connor made one of the most stressful times of my life much easier than expected. He was my lawyer for roughly a year and throughout that year he was attentive, answered my questions, and overall handled my case with professionalism and grace. Not one of my calls wasn’t returned from him and he would check in on me to make sure all of my business was being handled on time and correctly. 6/5 stars highly recommend this man if you’re ever in need of a lawyer.

Excellent Lawyer
I was arrested for DUI in October 2018. I retained Matt's services shortly after. It was one of the best decisions I ever made. Not only is Matt an excellent lawyer, but his demeanor and personality are exactly what someone needs during a stressful time. He was attentive, knowledgeable, and professional during the entire process. Matt was my lawyer for roughly a year and a half. During that time, I never had a phone call or an email that was not returned. He was truly there to help. He also made the entire experience manageable. There is a giant amount of information that needs to be processed and I never could have handled it without his services. I highly recommend Matt and he will continue to be the person I call for years to come.

The best lawyer
When I got my dui I didn't really know what to do. I haven't never been on the bad side of the law. I found O'Connor Law on Yelp. I decided with all the positive reviews this law firm could help me. So on a Sunday Matt O'Connor was willing to meet with me. It was one the only days I was available. He was upfront and honest about my chances of getting a wet and reckless instead of a dui. Matt was there every step of my dui journey. I'm grateful for his help. My dui did get knocked down to a wet and reckless and no suspended license either. Matt works hard on your behalf. My advice though ladies and gentlemen just get a Uber. But if you find yourself getting a dui call Matt O'Connor .

Look No Further
Matt O’Connor and his team are truly professional and courteous. No question was treated with disregard, and the utmost attention to detail was given to my case. O’Connor law is the place to go. I spoke with around 50 attorneys, and was contacted by twice as many. O’Connor law is the only firm for me. You will be treated respectfully and given the best possible result for your case. They really know how to set your mind at ease.

I have dealt with lawyers over the years and facing 10 years in prison,I must say Mr.O'conner is very professional and pleasant.He and an Investigator,Mr.Dudek Investigated my case thoroughly.He kept my wife updated at all times at the beginning when i got jailed and he did the same when he got me out to fight the case.For 5 yrs he fought with patience and honesty.It was life or death literally for me and my wife i take care of with our injuries and pain levels.3 weeks after the case my wife was unresponsive on our bed 15 mins. after i told her to please go lay down.After calling 911,the hospital said she was dead if i hadn't called.Mr.O'conners realistic expectations through out the case,were and still are phenomenal.He saved 2 lives that day and needs to be recognized more than this review.He should be recognized as one of the top attorneys in contra costa county.His professionlism will never be forgotten and he will be the first i call if ever needed.From me and my family,Thank you again Matt!

My Hero!
I hired Matthew O'Connor after calling and consulting with 10 other attorneys. It was quite an ordeal to sort through the incredible amount of defense lawyers in the area. My son would need a lawyer who was an expert to be able to work through a very difficult situation. Before my son was sent to prison he had violated his probation. Now it was certain the courts would revoke it and send him back to prison for a very long time. We had very little time to take care of the situation and I had limited funds. Then I found Mr. O'Connor. After our first conversation I knew that he was going to be able to help my son. Matthew--who is a former DA, knew the system backwards and forwards. He has worked on both sides of the fence and is able to use that knowledge to help people who are now in trouble with the law. He called and e-mailed almost daily to keep me informed of everything that was happening. The entire process took two weeks, and then it was finished! I cannot express in words the gratitude that I have for this lawyer, who with his complete expertise in the field of criminal defense, professionalism, and diligence, was able to recall all of my son's warrants and get him released him from his prior probationary responsibilities. What a great experience with a lawyer who was an expert in the field, very professional and prompt, continuously communicated with me, and most of all was so very kind and considerate. I would highly recommend Matthew O'Connor to anyone who needs a great criminal defense lawyer. I will never forget or could ever repay what Matthew has given back to me. My son and his freedom. He is my hero!

Very reassuring along with great representation in court which matters the most
Matthew handeld my case and even though my situation could have not of been worse he made an effort to show me not tell me my best option in his opinion as he had both my present and future in his decision. So I took his advice and I'm glad I did.

Relationship: Opposing Counsel on matter
"Matt O'Connor is a criminal defense attorney who will be there for you when you need him. I first met Mr. O'Connor when I was a state prosecutor and he was representing several clients facing very serious felony and misdemeanor charges. What struck me about Mr. O'Connor was his detailed knowledge of the law, his astounding presence in the courtroom, and his passion for his clients' interests. He impressed me so much that when I went into private practice myself, I often found myself calling him up for a second opinion on difficult issues when I was handling tougher cases. The advice I have received from Mr. O'Connor is always insightful and based on his years of experience litigating criminal cases."
