Cullen Millsap is a senior legal industry executive with a proven record of building high-performance growth engines for elite personal injury law firms. As the leader of Marketing, the New Client Team, and the Referral Department at GGL, Cullen oversees the systems and teams responsible for client acquisition, intake conversion, and strategic referral revenue across one of New Jersey’s most dominant PI practices.
Cullen’s approach blends brand authority with operational rigor. He has helped position GGL as a market leader through omnichannel marketing, data-driven decision-making, and reputation-based growth—where referrals from former clients, lawyers, and trusted partners represent a substantial share of total signed cases. His work reinforces GGL’s standing as the preeminent personal injury firm in New Jersey, with over $1 billion recovered for clients, statewide accessibility, and a reputation built over more than three decades.
Before GGL, Cullen served as COO and CMO for multiple personal injury firms, where he built and scaled intake departments, modernized marketing operations, and aligned growth strategy with firm culture and case quality. Across roles, he is known for building teams that perform under pressure, execute with discipline, and consistently exceed targets.
Cullen is also a combat veteran of the United States Marine Corps, an experience that continues to shape his leadership style: calm under fire, mission-focused, accountable, and deeply committed to the people he leads. He brings that same mindset to his work in the legal industry—driving results while building systems that last.
