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.

"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."
