About William K. Mattar

At a young age, William Mattar knew that he wanted to become a lawyer. His father was a lawyer in western New York, and William grew up watching him help people and make their lives better.

In high school, William told his dad that he was going to become a lawyer. When he got to college, he decided it was time to make his dream a reality.

BUILDING A LAW FIRM

Originally from Amherst, New York, William received a Bachelor of Science degree in psychology from State University of New York at Plattsburgh (SUNY Plattsburgh) in 1986. He then earned his Juris Doctor from Syracuse University College of Law in 1988.

After briefly working as a lawyer for another law firm, he opened William Mattar Law Offices in 1990 in Williamsville, New York. Originally, the law firm handled a variety of legal matters. Today, William Mattar focuses on motor vehicle accidents and has grown into its own building in Williamsville, with intake office locations in Albany, Rochester, Syracuse, New York City, and Long Island.

ALWAYS HELPING OTHERS

In his professional practice, William focuses on helping people by getting the best possible results for his clients in the shortest amount of time. But even when William isn’t at the office, he still finds ways to help others, and along with the firm supports many charitable organizations. He is an Eagle Scout and a former leader of the local troop of the Boy Scouts of America, Greater Niagara Frontier Council. Since 2002, he has also served as chairman for the Boy Scouts annual dinner, raising funds to support the organization which benefits more than 10,000 children. He is active in his church and is the past president or leader of many organizations.

William’s hobbies include spending time with his wife and children, cooking, hiking, and volunteering for the Boy Scouts of America with his sons, who have followed in his footsteps to become Eagle Scouts.

I called William Mattar because as the commercial goes “Hurt in a car, call William Mattar!” Mr. Mattar and the entire office was very understanding to my situation and went above and beyond to answer my questions. They made a very stressful time a little bit easier and made sure I had a positive outcome. I would recommend anyone to William Mattar!

I was involved in a three (3) car accident. I fractured my hand and had to get seven (7) screws in it. I chose William Mattar because the phone number was easy to remember! I am very pleased with my settlement and how quickly it was settled. Anytime I had a question there was always someone to answer and I didn’t have to wait for a response. Everyone was very nice and always professional. I would refer William Mattar Law Offices to anyone!

I was the passenger in the vehicle when our driver fell asleep at the wheel and swerved off the road. I was taken by Mercy Flight to Strong Memorial hospital. After my treatment, I heard about William Mattar and asked people I trusted for their opinion on his firm. He was highly recommended, so I chose him as my lawyer. I feel that the case was handled in a timely manner, and I would come back to William Mattar again.

Between hardly any communication (except for by me), a very lengthy case with no direction, and minimal settlement, with damaging injuries. The only thing I can determine is that there was too much fear to prosecute the largest commercial landowner in the Buffalo area. He got a free pass from the little guy by way of WM, while the business I owned struggled without me there. I would never trust him again, for the 2 minutes I saw him. No thanks.
