Client Testimonials

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.

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.
