A leader who knows how to power through complex legal issues
In an environment where employers face unprecedented scrutiny, Gabrielle Levin has distinguished herself as a pragmatic, steady, and deeply trusted leader. As co-leader of Mayer Brown’s US Employment Litigation and Counseling Group, she helps organizations navigate highly sensitive workforce challenges at the intersection of legal risk, business priorities, and public perception. Gabrielle’s leadership philosophy centers on clarity, credibility, and balance. She is known for cutting through complex and fast-evolving legal issues to deliver practical, actionable guidance. Her approach is particularly impactful in areas where legal considerations are inseparable from reputational and strategic concerns – ensuring that clients are not only compliant with the law, but also well-positioned to move forward with business objectives.
This is especially evident in her work advising employers on legally compliant DEI strategies during a time of heightened regulatory and litigation risk. Gabrielle has taken on a visible leadership role in counseling organizations facing scrutiny from regulators, state attorneys general, and enforcement agencies. She brings a nuanced understanding of the legal landscape, coupled with sound judgment, enabling clients to adapt to shifting expectations while managing risk in a thoughtful and sustainable way.
Her experience reflects both the breadth and significance of her leadership. Gabrielle represented UBS in a landmark Sarbanes-Oxley whistleblower case that resulted in a favorable Second Circuit ruling after consideration by the US Supreme Court – widely viewed as one of the most consequential whistleblower decisions in recent years. She has also advised Citigroup in connection with a high-profile multistate inquiry into its DEI practices and represented clients in complex disputes involving senior executives and substantial financial stakes.
Beyond her client work, Gabrielle demonstrates leadership through her commitment to mentorship and team development. She invests in developing the next generation of employment litigators, fostering collaboration and encouraging thoughtful, solutions-oriented problem solving. Her ability to guide both clients and colleagues through challenging situations underscores her reputation as a composed and effective leader.
