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 was struck in my driver’s side door by an oncoming vehicle. After my emergency room hospitalization, I sought chiropractic treatment. My doctor said William Mattar. The staff was very patient, always returning calls and answering whatever questions I had. Whenever I didn’t understand something, they explained it thoroughly. I would definitely recommend anyone to William Mattar, and I would come back to him again.

I was a passenger in a car when another car made an illegal u-turn and struck us. My head, neck, and back hurt. I called William Mattar, because I wanted someone reputable who could handle my case and help me deal with this stressful situation. I was treated very well. I knew I was in good hands. Overall, I feel happy and glad I can move forward. I’m going to miss talking with everyone at the firm. I recommend William Mattar to everyone.
