Orrick appoints seven more Houston office partners

Orrick has appointed seven additional partners in the international law firm’s new Houston office: Carlos Treistman, Bill Parish, Rodrigo Dominguez, Jonathan Ayre, and Joe Roger all join from Morgan Lewis; and David Ronn, who will join the firm on Feb. 17, and Barbara de Marigny join from McGuireWoods. This team brings talent and depth in mergers and acquisitions (M&As), capital markets, tax, and energy and infrastructure transactions and projects, including substantial experience in cross-border transactions throughout Latin America.

Orrick opened its Houston office last month. With this latest group, the Houston office comprises 22 lawyers from seven different firms.

Treistman, the founder and former co-chair of Morgan Lewis’s Latin America team and former head of its Houston Corporate and Business Transactions practice, will also co-chair, with Dominguez, Orrick’s Latin America practice. Treistman specializes in cross-border M&As, joint ventures, and other international transactions. Rodrigo is licensed in Mexico, New York, and Texas, and counsels clients on Latin America local and cross-border transactions, including opportunities in the Mexican energy sector resulting from Mexico’s recent reform of its hydrocarbon and electricity laws. He also counsels Latin America-origin clients doing business in the US. They are joined by corporate practitioner Parish, who brings 20 years of corporate, M&A, and private equity experience, including energy transactions and cross-border M&A and other transactions throughout Latin America. Parish recently represented a Mexican developer in bids for several natural gas pipeline projects tendered by the Mexican Federal Electricity Commission (CFE).

Ayre and Roger are energy transactional lawyers focusing in particular on upstream and midstream oil and gas assets, liquefied natural gas (LNG) projects, and electric power generation facilities. They have substantial experience in M&As, joint ventures, project development, and construction and other commercial contracts. Ayre and Roger will join Orrick’s expanding Houston energy team and the firm’s 130-lawyer global Energy & Infrastructure practice.

Ronn, who served as co-leader of McGuireWoods’ Oil and Gas team, focuses on corporate and securities matters for master limited partnerships and other clients in the energy sector. He advises clients on all types of corporate securities offerings and has experience in cross-border oil and gas-related transactions. De Marigny, a board-certified tax law specialist, focuses on tax structuring for M&A transactions in the energy sector. She has experience with tax issues arising in partnership, joint venture, and alternative investment structures, including the use of partnership structures for strategic acquisitions. Ronn and De Marigny add further depth to Orrick’s capital markets, transactional and tax capabilities, including master limited partnership experience, and enhance the firm’s ability to support clients in key areas such as energy and technology. Ronn will serve as the Houston Office Hiring Partner, responsible for on-campus and lateral associate recruiting.

The firm earlier announced that Houston partner Blake H. Winburne will serve as global co-head of the firm’s Energy & Infrastructure Group. The other energy partners who recently joined the Houston office are Dahl Thompson, Matt Archer, Brad Gathright, George Humphrey, Giji John, and Darrell Thomas.

The other lawyers who have joined Orrick’s Houston office are IP and commercial litigators Claudia Wilson Frost, Jeffrey Johnson, and Katherine Treistman, and public finance practitioners Todd Brewer, Hoang Vu, Marcus Deitz, Kathryn Garner, and J. Kent Friedman.
