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.
