This strategic expansion of the firm’s service offerings will operate at the intersection of law, business and government.
Eric Brophy will join the firm as a Member, effective September 1, 2025, following his tenure as Deputy Chief of Staff for Economic Growth to New Jersey Governor Phil Murphy.

CSG Law’s new Government & Regulatory Law Group will advise clients in legal and administrative proceedings before numerous government entities and in challenges to adverse agency action, at both the trial and appellate court levels. The Government & Regulatory Law Group will assist clients in navigating procurement, regulatory compliance, and “pay-to-play” rules ensuring that businesses remain compliant and competitive. The group will also advise clients on policy strategies to help maximize their business interests in New Jersey.
“I have known Eric both personally and professionally for more than a decade, and I can think of no better person to partner with to grow the Government & Regulatory Law practice at CSG Law,” said Patrick O’Reilly.
