NEW YORK—December 14, 2022—Eleven exceptional lawyers reflecting O’Melveny’s broad ranging capabilities have been elected to the firm’s 2023 partner class: Billy Abbott (Tax—Silicon Valley), Matt Cowan (White Collar Defense & Corporate Investigations—Los Angeles), Tim Heafner (Entertainment & Media—Century City), Mattie Hutton (Product Liability & Mass Torts/Life Sciences Litigation—Washington, DC), Matthew Kremer (Restructuring—New York), Mark Liang (Intellectual Property & Technology—San Francisco), Deanna Rice (Financial Services/Supreme Court & Appellate Litigation—Washington, DC), Esteban Rodriguez (Consumer Class Actions—Los Angeles), Amanda Santella (White Collar Defense & Corporate Investigations—Washington, DC), Maria von Schack (Project Development & Real Estate—New York), and Jillian Weinstein (Assistant General Counsel—Firmwide).
“Each of our newly elected partners epitomizes the very best of O’Melveny by demonstrating an unwavering commitment to our firm and our clients,” said Bradley J. Butwin, Chair of O’Melveny. “They have distinguished themselves not only as top litigators and dealmakers but also as champions of our shared values. These outstanding lawyers strengthen and enrich our partnership with their diverse backgrounds, experiences, and perspectives. I look forward to all that this impressive class will achieve in the years to come.”
This is the eighth consecutive year that at least 50 percent of O’Melveny’s newly promoted partners are women, racial and ethnic minorities, and/or LGBTQ+, with eight of 11 members of this year’s class being from those historically underrepresented groups. Looking at the past nine years as a whole, more than two-thirds of the firm’s total new partner promotions have been individuals from those groups.
A talented and versatile corporate tax lawyer, Billy Abbott is a trusted advisor to fund managers, private equity and venture capital investors, and corporate clients on the tax aspects of public and private M&A, capital markets, asset management, and real estate transactions. He regularly advises on tax structuring for complex transactions, including cross-border matters and multi-jurisdictional acquisitions. Abbott is especially adept at explaining tax-advisory information to clients of O’Melveny’s Asset Management practice. He has a strong commitment to pro bono work and to diversity, helping the firm recruit LGBTQ+ attorneys and representing the firm at diversity career fairs. Abbott received his law degree from Stanford, where he served as Senior Production Editor of the Stanford Law Review.
Matt Cowan is a key West Coast member of O’Melveny’s White Collar Defense & Corporate Investigations Practice.

Cowan also provides regulatory and governance advice to companies and universities, and he has considerable experience in complex e-discovery, compliance, employment, healthcare, and privacy matters. His judgment and expertise have made him a trusted board-level advisor. And he devotes significant time to pro bono efforts, recently leading the O’Melveny team in Davis v. Nevada, a case that resulted in sweeping legislative change to Nevada’s system of indigent defense representation. Cowan earned his law degree cum laude from the University of Michigan School of Law.
Tim Heafner is an experienced litigator who represents a broad range of “A-List” clients in the sports and entertainment industries, from major motion picture studios and media conglomerates to boxing promoters and superstar athletes.

Liang has played an important role in many of the firm’s most significant IP&T trials, both in federal courts and before the International Trade Commission, and he is equally skilled in leading inter partes review proceedings.
