Celebrating DWGP’s 55th Anniversary (2000’s)

Continuing DWGP’s 55th anniversary retrospective, we turn to the 2000s.

During the 2000s, recognizing Jeff Genzer’s critical role in advising clients regarding the pulse of Washington, DC, the firm is renamed to its current form -- Duncan, Weinberg, Genzer & Pembroke. The firm continued to expand its presence with the opening of its California office on September 7, 2004, by Sean Neal. The firm’s major work during this time included assisting clients in obtaining funds under the American Reinvestment and Recovery Act of 2009; a major federal initiative that supported energy infrastructure and renewable energy development. DWGP also helped clients navigate the maturation of the regional transmission organizations and independent system operators nationwide. Additionally, the Energy Policy Act of 2005 initiated sophisticated new regulatory structures to ensure the reliability of the electric grid, and DWGP advised many of its clients on how to adapt to these new regulatory frameworks.

With a new name and the opening of its California office (pictured below, a celebration of Sean Neal’s move to open DWGP’s California office), the firm moved into the next decade as the energy industry continued to evolve.

Next up: the 2010’s.
