Greenberg Traurig has secured the UK head of Osborne Clarke's energy and infrastructure finance practice, the third senior hire in as many months into its City energy and natural resources team.
Dominic O'Brien has joined as a shareholder after nearly five years at Osborne Clarke, before which he was head of the London banking and finance practice at Orrick. His experience covers the lifecycle of energy and infrastructure projects, including traditional greenfield project financing, secondary and brownfield acquisition financing, and corporate financing for operational utilities, developers and energy providers.
O'Brien's hire continues the build-out of Greenberg Traurig’s London office, which has added more than 20 shareholders over the past few years focused on corporate, private equity and energy and infrastructure and now has around 190 lawyers.
“The firm's focus on energy and infrastructure across the globe is in part driven by the continued growth of our London team," Richard Rosenbaum, Greenberg Traurig's executive chairman, said. "Dominic's arrival reflects this investment and adds substantial financing experience."
Since September the firm has also added Osborne Clarke partner Hannah Roscoe and Sidley Austin counsel Sofiya Bumagin as shareholders in its London energy and natural resources practice.
The firm noted that O’Brien, Roscoe, Bumagin and energy shareholder Shashank Krishna brought experience spanning energy and infrastructure finance, M&A, private capital investment and project development, and would draw on its wider London infrastructure and finance capabilities, including shareholders Richard Ceeney, who joined last year from Reed Smith and focuses on major infrastructure and energy projects, and Kevin-Paul Deveau, whose practice spans infrastructure and project finance, private credit and acquisition finance.
O'Brien’s move follows a strong financial performance in 2025 by the firm, which grew revenue 11.8% to surpass $2.9bn against a 10.1% growth in profit per equity partner to $2.9m, even as its equity partner count held steady.
It comes as law firms are aggressively hiring energy and infrastructure partners in London, driven particularly by US firms expanding their local presence and high demand for expertise in the global energy transition.
Earlier this week Akin added Freshfields partner James Chapman, who focuses on complex energy and infrastructure transactions, echoing similar recent moves by firms like Simspon Thacher and White & Case.
O’Brien said Greenberg Traurig's "international platform and commitment to the energy and infrastructure sectors made this an attractive opportunity."
He added: "The strength of the team in London, combined with the firm's international reach, provides a strong platform for collaboration on complex transactions. I look forward to working with Shashank, Hannah, Sofiya and colleagues across the firm's global network, particularly on cross-border financing transactions across EMEA and Asia.”
