Matt focuses his corporate transactional practice on helping his clients solve the increasingly complex and sophisticated challenges of acquisitions, financings, and governance matters.

Leveraging his broad skill set and unique background as an international negotiator, Matt serves as a strategic counselor to his clients, working with them to structure, negotiate, and execute various transactional arrangements, including mergers and acquisitions, growth equity investments, joint ventures and other financings.  Matt also serves as outside general counsel to several early stage clients, advising them on all aspects of their legal needs.  Matt’s clients span a broad range of corporate organizations, including well-known private equity sponsors, large multi-national corporations, and both early-stage and late-stage grown companies, across a variety of industries including technology, pharmaceuticals, life sciences, telecommunications, financial services, consumer products, energy, and manufacturing, among others.

Prior to joining Mintz, Matt worked at the New York office of Torys LLP and the Washington, DC office of Weil Gotshal.  Prior to law firm service, Matt ran the sales department of the then-largest college marketing program where he sold $1 million+ marketing programs to Fortune 500 companies.

In addition to his corporate practice, Matt is a recognized international negotiator and legal advisor.  In 2010 the United Nations and African Union appointed Matt the Principal Legal Advisor to the Darfur Delegation in the Darfur Peace Negotiations.  Embedded in Doha, Qatar as an official member of the Darfur delegation, Matt lead a team of over two dozen international 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.

During law school, Matthew was an editor of the American University International Law Review and was the president and co-founder of the International Trade Law Society at American University.
