In addition to representing the injured and their families in the trial court, Matthew has notable experience in the appellate courts of several states and in the Illinois Supreme Court.

Matthew graduated from The John Marshall Law School with his Juris Doctorate and a Certificate in Trial Advocacy, which was awarded to less than 3% of students. At The John Marshall Law School, he won the Dean Herzog Moot Court Competition, while also writing the award-winning Best Brief of the competition. Supplementing his education during law school, he clerked for the Cook County Public Defender's Office, as well as the Presiding Judge of the Fifth Municipal District of Cook County.
