Prior to joining Mintz Levin, Matt worked at a law firm in New York advising public and private companies in various mergers and acquisitions, including cross-border transactions, leverage buy-outs, management buy-outs, and takeovers. Additionally, Matt served as a summer associate and then an associate with the Washington, DC office of another New York-based law firm, where he advised sovereign governments, public and private companies, and industry associations on investment disputes, WTO, bilateral, and domestic trade remedy mechanisms as well as corporate clients on transactional compliance with U.S. export control regulations.  Prior to law firm service, Matt ran the sales department of the then-largest college marketing program where he liaised directly with C-level executives and sold $1 million+ marketing programs to Fortune 500 companies.

In addition to his corporate practice, Matt is a recognized international negotiator, having been appointed by the United Nations and African Union as the Principal Legal Advisor to the Darfur Delegation in the 2010 Darfur Peace Negotiations.  Based in Doha, Qatar for two years, Matt was a key member of the Darfur delegation and lead a team of legal and policy advisors on all aspects of the peace negotiations including issues related to power and wealth sharing, the negotiation of a $2 billion development fund, the overhaul of the petroleum and natural resources sectors, and the formation of a regional government for Darfur.

From 2006 to 2011, Matthew was affiliated with the Public International Law & Policy Group (PILPG) in Washington, DC where he worked on over a dozen post-conflict legal and policy initiatives including leading the first-ever surrender to the International Criminal Court, amending the Iraqi Constitution, designing war crimes witness protection programs in Uganda, and advising on the establishment of the Republic of South Sudan.
