Experience

Steve’s work focuses on complex antitrust and cybersecurity litigation. He also represents clients in civil investigations initiated by State Attorneys General. Steve’s strength is his ability to handle diverse matters, from taking on key roles in case initiation and discovery through participating in leadership strategy meetings to ensure that the case team is prepared to handle all issues that may arise. Steve is frequently tasked with leading discovery, including implementing review-related protocols, taking and defending depositions, serving as a mentor to newer attorneys, and helping to ensure that our firm and our co-counsel continue to achieve outstanding results for our clients.
