William Mattar, P.C. Firm History

William Mattar, P.C. is a personal injury law firm that has been serving the State of New York for 30 years. In 1990, William Mattar opened his original law office on Main Street in Williamsville practicing general law. The firm saw itself branded as William K. Mattar, P.C. in October 1995. By 1997, the firm had outgrown its current space and moved into a new office across the street.

In 2005, William Mattar built our 6720 Main Street office and moved in with 4 attorneys and 5 legal assistants. January 2011 saw the firm’s name changed to William Mattar, P.C. The firm continued to grow and reached approximately 90 employees in 2014, requiring additional office space. William Mattar purchased the old building next door to build a brand new office, completed in February 2015.

Over the years, William Mattar, P.C. has expanded outside of the Buffalo area and now has office locations in Rochester and Syracuse. With over 120 employees across New York State, William Mattar, P.C. continues to grow to serve our clients and communities.
