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 what was recognized as the Best Brief of the competition.
