Daniel A. Sasse is a partner in Crowell & Moring's Orange County office and a member of the firm's Management Board. His practice focuses on antitrust law, including antitrust litigation, government investigations, defending mergers, acquisitions and joint ventures, and antitrust compliance issues. He has extensive experience in regulated industries including health care, telecommunications, and energy.

Dan has devoted a substantial portion of his practice to antitrust cartel litigation. This practice includes defending clients in criminal investigations and civil litigation as well as representing many Fortune 500 companies as plaintiffs in recovery actions when they have been the victim of price-fixing cartels. As a leader in the firm's Plaintiff's Recovery Practice, Dan has helped clients recover more than $500 million in recent years, and has helped turn legal departments from cost-centers into profit-centers.

In 2014 and 2015, Dan was recognized as an “Up and Coming California Antitrust Attorney” by Chambers USA, noting that clients appreciate that he is “incredibly responsive” and "cerebral but also understands how businesses work in connection with litigation."  He has also been recognized as one of the leading competition attorneys in the U.S. and listed in Global Competition Review's Who's Who Legal: Competition 2015.

The Daily Journal has recognized Dan as one of "10 Emerging Law Firm Leaders in California." Dan has also been named as a "Rising Star" by the Southern California Chapter of the Association of Corporate Counsel (ACC-SoCal) and by Competition Law360, who placed him on the nationwide list of 10 competition lawyers under 40 to watch. Additionally, the Daily Journal identified one of Dan’s cases as among the Top 25 California Plaintiff's Verdicts. Since 2007, Dan also has consistently been recognized as a "Southern California Super Lawyer" and "Rising Star" in Antitrust Litigation.

Dan is a leader in the Orange County Bar and community organizations. He serves on the ABTL/OC Board of Governors, is a fellow of the American Bar Foundation, and serves as lawyer representative to the Ninth Circuit Judicial Conference. He is also a past president of the Federal Bar Association/OC, and he served as a member of the CD Cal Local Rules Committee. Dan is also heavily involved in Crowell & Moring's award winning pro bono program.

Before joining Crowell & Moring, Dan clerked for two years for the Honorable, H. Dean Whipple, Chief Judge U.S. District Court for the Western District of Missouri. He received his B.A., summa cum laude, from Valparaiso University in 1994 and a law degree with distinction from Emory University School of Law in 1997. At Emory, Dan was a member of the Emory International Law Review and Jessup International Moot Court Team.
