When I needed a lawyer I contacted the law firm of Cassisi and Cassisi. I was immediately convinced I made the right choice. I was treated with kindness and professionalism. My lawyer, Matt Maloney went through my case with me. I was kept informed of each step of my legal process. The eventual successful outcome happened quicker than I expected. I recommend this firm to anyone in need of very capable and client driven attorney's.

Unfortunately a few years back I found myself in need of a lawyer. I interviewed a few law firms and was very uncomfortable with the attitudes from the offices.
I then found Cassisi and Cassisi, what a difference. From my first call I felt like someone cared about me. The staff was so accommodating working around my schedule. Then speaking with Mr. Cassisi I realized this was the firm for me. They were there for me step by step always answering any questions. It made the experience so easy. I would highly recommend them to my friends and family if they ever needed a lawyer.
