Matt navigates his clients through complex corporate transactions including mergers and acquisitions, joint ventures, growth equity, venture capital and other minority investments, and restructurings in the U.S. and abroad.

Leveraging his broad skill set and unique background as an international negotiator, Matt serves as a strategic counselor to his clients, leading teams that structure, negotiate, and execute various transactional arrangements, with a particular focus on private equity mergers and acquisitions involving founder-run businesses. Matt also serves as outside general counsel to multiple clients, advising them on all aspects of their legal needs and taking several clients from formation to funding to IPO, and beyond. 

Matt is a sought after commentator on the Private Equity industry, routinely speaking to trends and developments affecting sponsors, limited partners, and others participating in direct and indirect private equity investments.

Matt’s clients span a broad range of corporate organizations, including well-known private equity sponsors (committed funds, independent sponsors, and family offices), large multi-national corporations, and both early-stage and late-stage growth companies, across a variety of industries including technology, life sciences, healthcare, telecommunications, financial services, consumer products, energy, and manufacturing, among others.

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 led 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. Since 2006, Matt has been affiliated with the Public International Law & Policy Group (PILPG) in Washington, DC where he has 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.  Matt currently serves in a pro bono capacity as a Senior Peace Fellow for PILPG advising on the implementation of the 2020 Sudan Peace Agreement and efforts towards a ceasefire in Ukraine.
