Originally from Flagstaff, Arizona, Matt Cox came to Eugene to attend the University of Oregon where he earned both his undergraduate degree and then his law degree in 1998. After graduation from law school he began working as an Assistant District Attorney for the Lane County District Attorney's office, Criminal Division from September 1998 to April 2004. Thereafter, Matt jointed Leahy Cox, LLP (then named Harold, Leahy & Kieran).

Professionally, Matt is best known for his work in litigation (including criminal prosecution), family law, contracts, and arbitrations. In his own words, Matt identifies the one problem he is best at solving for clients is, "Helping clients to make a sound decision concerning whether or not they should settle the case or move forward with litigation. Understanding the costs and the pros / cons of litigation is a great help in explaining the situation to my clients."

Matt is often described as being a hard worker, fair, and even as a fierce advocate who treats the other side with respect so as not to make the adversarial process more expensive or difficult.

When asked about his professional passion, Matt is dedicated to working as a Municipal Court Prosecutor.

When not at work, Matt can be spotted spending time with his wife and daughter, running, or out on the golf course. Matt enjoys volunteering at the Willamalane Senior Center on their Senior Law Day.
