William Mattar is a licensed New York attorney known for his focus on motor vehicle accident cases and his well-known slogan, “Hurt in a car? Call William Mattar.” Since founding his law firm in 1990, he has built one of the state’s leading personal injury practices with offices across New York, including Rochester. His team helps clients with car, truck, and motorcycle accident claims, handling insurance negotiations and compensation recovery.

Early Life

William K. Mattar grew up in Amherst, New York, where he was influenced early by his father’s work as a lawyer, which helped him decide on a similar path. He earned a Bachelor of Science degree in psychology from State University of New York at Plattsburgh in 1986, and then completed his Juris Doctor at Syracuse University College of Law in 1988. As a youth, he became an Eagle Scout and later served as a leader with the Boy Scouts of America’s Greater Niagara Frontier Council, showing his commitment to community service long before he started his legal career.

Career

William Mattar established his own law firm in 1990 in Williamsville, New York, after working briefly for another firm. The firm began with general legal work, but over time narrowed its focus specifically to motor vehicle accidents throughout New York State. Under Mattar’s leadership the firm expanded beyond its original office, adding intake locations in cities such as Rochester, Syracuse, Albany, Long Island and New York City, making it easier for clients across New York to access help.

Mattar’s firm operates on a contingency-fee basis, meaning clients often pay no legal fee unless their case succeeds. The team handles building a case from the evidence gathering stage all the way through to negotiating with insurance companies or going to trial, depending on the situation.

Through many years of service the firm has grown significantly, it has more than 120 employees and has secured hundreds of millions in recoveries for clients injured in accidents.
