William Mattar Career
William Mattar is a prominent American personal injury lawyer and the founder of William Mattar, P.C., a Williamsville, New York-based firm devoted exclusively to automobile accident cases. Over more than three decades, he has built one of New York State’s largest law practices focused on motor vehicle collisions.
Under his leadership as owner and president, the firm handles every aspect of car, truck, motorcycle, bicycle, and pedestrian crash claims. Mattar’s name and trademark slogan “Hurt in a car? Call William Mattar!” have become widely recognized across New York, reflecting his longstanding commitment to representing injured drivers and passengers.
Legal Education & Entry into Personal Injury Law
Mattar earned a Bachelor of Science in psychology from the State University of New York at Plattsburgh (1986) and then a J.D. from Syracuse University College of Law (1988). He was admitted to the New York State bar in 1989 and initially practiced for a short time at a general personal injury firm.
Seeking to build his own practice, Mattar opened his own law office in 1990. These early years helped him gain experience in accident cases before he devoted his firm entirely to car-crash litigation.

William Mattar opened his first office in 1990 on Main Street in Williamsville. The firm was initially named William K. Mattar, P.C. (later shortened to William Mattar, P.C. in 2011).
In the early 1990s it handled a variety of injury cases, but Mattar soon honed its focus on traffic accidents. By 1997 the firm had already outgrown its original quarters and moved to larger space nearby.
In 2005 Mattar built a new dedicated headquarters at 6720 Main Street in Williamsville, starting with a team of 4 attorneys and 5 legal assistants. The firm name was officially updated to William Mattar, P.C. in January 2011.

The firm did not remain confined to Western New York. It opened branch offices in upstate cities including Rochester and Syracuse, and established intake centers in other regions (for example, the Capital District and Long Island) to serve clients statewide.
Today, the William Mattar Law Offices employ well over 120 people across New York State, with its main headquarters in Williamsville and additional locations in Buffalo, Rochester, and Syracuse.
This network allows the firm to handle cases from all corners of New York, maintaining the founder’s vision of statewide reach.

The practice areas specifically include claims for wrongful death and catastrophic injuries (such as brain and spinal trauma) arising from motor vehicle crashes. In each case, the firm emphasizes aggressive advocacy and client support.
The office offers free initial consultations and works on a contingency-fee basis (meaning clients owe no fee unless the case is won). Mattar’s team prides itself on prompt communication and accessibility.
