Steptoe LLP, led by Daniel Mullen in Washington DC, stands out for its expertise in the life cycle of energy projects including development, financing, and M&A, as well as regulatory matters. With a breadth of capabilities, the team has an impressive and expanding client roster comprised of notable names from the energy and financial services sectors. The practice’s aptitude has been bolstered by the arrival of project finance specialist Philip Corsello who joined the firm in February 2024. Corsello is noted for his experience advising institutional investors, lenders, and sponsors on financing transactions ranging from private placements to tax equity and back-leverage financings. Washington DC’s Timothy Moran is another notable name and concentrates on the development, financing, acquisition, and sale of renewable energy projects. On the regulatory front, Washington DC-based Chris Zentz is the main contact in the team.
