Orrick Continues Growth of Energy & Private Equity Teams with Rising Star in Houston


  • David Aaronson joins the firm as a partner focused on advising on complex M&A transactions in the energy sector, with a particular focus in counseling private equity investors, sponsors and portfolio companies.
  • He is the fifth partner to join Orrick’s Energy & Infrastructure practice since February, joining a team that IJGlobal named Energy Legal Adviser of the Year at its 2021 North America awards.
  • David joins Orrick from Willkie Farr & Gallagher.

“As the U.S energy sector continues to face evolutionary pressure to address carbon intensity, sustainability and security of supply, we’re thrilled to add a partner of David’s talent and perspective to our team. His deep experience and relationships across the oil & gas value chain, paired with Orrick’s breadth of practice in conventional and renewable energy, reinforces our commitment to serving clients at the leading edge of the energy transition, a strategic focus area for the firm,” said Blake H. Winburne, Orrick’s Energy & Infrastructure sector leader.

David’s experience includes upstream, midstream and downstream M&A transactions, involving conventional and unconventional plays, as well as alternative fuels and other emerging asset classes. He regularly acts for private equity and infrastructure investors, as well as majors and mid-majors, on complex joint ventures and operating agreements.

“Orrick has a stellar energy, tech and finance platform that is an ideal fit for my practice today and for where markets are heading in the future. Joining a team that has Orrick’s depth of resources associated with energy transition positions me incredibly well to serve a market that is undergoing a historic moment of change,” added David.

David follows the arrivals this year of energy finance advisors Jeff Kayes and Adam Griffin from Baker Botts, corporate PPA advisor Teresa Hill from K&L Gates and project development advisor Julia Balas from Morrison & Foerster.

Orrick’s U.S. renewable energy practice is ranked Band 1 by Chambers. The firms ranks #3 for renewables globally by Inframation.
