I had a court case in Lynn. I called Mr, O'Malley and he asked me for a consultation. The best part was that he got my police report before I even got there. We had a good consultation.

"I recently observed Attorney O'Malley defend a client at a jury trial for a criminal matter in Peabody. I was impressed. It was obvious he was thoroughly prepared - it seemed he knew the facts of the matter better than the testifying officer. He was quick on his feet, involved his client in all the important decisions, and won a NOT GUILTY. Well done!"
"Attorney O'Malley is a well-known and highly skilled advocate on the North Shore. Great lawyer and a pleasure to work with."
"I endorse this lawyer. I observe this Attorney in the court room. He is extremely competent and goes to all extreme to give his client the best representation. He is knowledgeable and dedicated. You will be hard to find a better lawyer in Essex County."
