As antitrust and competition law take on growing significance—driven by increased federal and state enforcement, expanding private litigation, and heightened scrutiny of pricing and transactions—Mandelbaum Barrett PC has formally launched an Antitrust Practice to help clients address these developments with sound, strategic guidance.
The practice is co-chaired by Harrison McAvoy, who recently joined the Firm and whose work spans high‑stakes antitrust litigation and counseling across industries including healthcare and pharmaceuticals, and Grant Petrosyan, an experienced litigator with a focus on advising clients in complex disputes and antitrust matters. They are supported by a broader team of lawyers with competition law experience and with backgrounds in federal prosecution, intellectual property, complex commercial litigation, and criminal defense, bringing the depth needed for the sophisticated issues faced by clients in today’s marketplace. Together, the group offers the Firm’s clients practical, real-time antitrust counseling on compliance, strategic transactions, and risk management, and represents companies as both plaintiffs and defendants in antitrust litigation.
Over the past year, Mandelbaum Barrett PC has experienced significant growth across key practice areas, expanding its capabilities in response to evolving client needs. The formal launch of the Antitrust Practice reflects both that momentum and a noticeable shift in how frequently antitrust considerations are shaping business strategy.
“We’re seeing antitrust issues come up in places clients didn’t expect even a few years ago, whether in routine business decisions, competitor interactions, or transactions that draw regulatory attention,” said William S. Barrett, Firm CEO. “Our approach is grounded in both the legal framework and the commercial realities our clients are operating in. This is about giving clients clear, practical guidance when the stakes are high and the path forward isn’t always obvious.”
The team advises clients across the full spectrum of antitrust matters, including litigation, government investigations, merger review, and compliance. Its work reflects the reality that competition concerns often arise unexpectedly and require immediate, strategic decision-making informed by both legal and economic considerations.
Harrison noted that companies are increasingly confronting antitrust risk earlier, and in more varied contexts, than in the past.
“Antitrust issues don’t just emerge in investigations or litigation anymore—they come up in pricing decisions, distribution strategies, data-driven business models, and M&A activity,” said Harrison. “What clients need in those moments is advice that’s not theoretical, but grounded in how these issues actually play out, so they can move forward with confidence.”
The practice is built to work closely with clients at every stage, from proactive compliance and risk assessment to litigation and regulatory review, while staying focused on the issues most likely to affect outcomes.
Grant emphasized the team’s focus on delivering clear, efficient guidance in high-pressure situations. “Our job is to focus on what really matters, cut through unnecessary complexity, and give clients straightforward advice that aligns with their business objectives.”
The launch was recently featured in the New Jersey Law Journal, Law360, ROI-NJ, New Jersey Business, NJBIZ and Competition Policy International.
