O’Melveny Earns Top Rankings in Chambers USA 2021

May 25, 2021


LOS ANGELES—May 25, 2021—Chambers has recognized O’Melveny as a leading law firm in 37 practice areas in the 2021 edition of Chambers USA: America’s Leading Lawyers for Business. This year, Chambers ranked the firm in Band 1—the top rank—in Corporate Crime & Investigations (Nationwide), ERISA Litigation (Nationwide), General Commercial Litigation (NY), and White-Collar Crime & Government Investigations (NY).

In all, Chambers recognized 60 firm lawyers across 19 practice areas. Nine earned Band 1 status, including five who were ranked in their category nationally:

  • Seth Aronson: Securities Litigation (California)
  • Jared Bartie: Sports - E-Sports (Nationwide)
  • Robert Blashek: Tax (California)
  • Brian Boyle: ERISA Litigation (Nationwide)
  • Apalla Chopra: Labor & Employment (California)
  • Jeffrey Fisher: Appellate Law (Nationwide)
  • Greta Lichtenbaum: International Trade (Nationwide)
  • Daniel Petrocelli: Trial Lawyers (Nationwide) and Media & Entertainment (California)
  • Eric Rothenberg: Environment (New York)

For the 10th consecutive year, Chambers named O’Melveny partner Walter Dellinger to its ranking of “senior statespeople,” a designation awarded to lawyers with exceptional recommendations in their field. O’Melveny Of Counsel Theodore Kassinger also received the “senior statesperson” accolade this year. And Chambers once against named Daniel Petrocelli, Chair of O’Melveny’s Trial Practice and Vice Chair of the firm, a “Star Individual”—an elite ranking above “Band 1.”

Chambers also recognized four O’Melveny lawyers—Elizabeth Dubeck, Denise Raytis, David Ribner, and Jennifer Taylor—as “Up & Coming” lawyers, a ranking given to practitioners at the forefront of their generation. Ribner is the only non-partner at any firm ranked as Up & Coming in the International Trade: CFIUS Experts category.

“We are proud once again to be ranked so highly by Chambers,” said Bradley J. Butwin, Chair of O’Melveny. “Our strong showings, year after year, tell the story of our unflagging commitment to our clients and of our drive to excel.”
