Excellent Law Firm
The team at Lyons & Lyons helped me win a medical malpractice case recently. The experience I had working with Lyons & Lyons was more than professional, I cannot compliment the staff enough for their countless hours of hard work put towards my case as well as keeping me updated as the case progressed. I will be recommending this firm in the future to those who may be needing similar legal services as me.

I wish Lyons had been my first call
My experience with Lyons was very pleasant. With confidence, he took my case (which was a difficult case) after I had already been turned away by two other attorneys. He is very professional, but also very caring. He didn't make me feel as if he was only my attorney but also a friend I could trust. He made sure to keep me up to date with what was going on, and was available to answer any questions or concerns I may have had. My case lasted for several years before a very comfortable agreement was met, but after all was said and done...I felt well protected with Lyons on my side.
