Brian Lansing is an experienced trial lawyer, former legal executive, and trusted counselor to business and institutional leaders facing complex litigation, investigations, and compliance challenges. With more than 30 years of experience across national law firms, Fortune 200 companies, government agencies, and the judiciary, Brian brings a rare combination of courtroom credibility, executive‑level judgment, and operational insight to every matter he handles.

Brian has litigated, tried, and managed hundreds of civil and criminal cases in federal and state courts and on appeal. His practice encompasses complex commercial disputes, white‑collar defense, government and internal investigations, intellectual property matters, and regulatory and compliance counseling. He is frequently called upon to resolve high‑risk disputes, lead sensitive investigations, and advise boards, executives, and business presidents during periods of legal, regulatory, and reputational crisis.

Most recently, Brian served as Associate General Counsel for Litigation and Compliance at W. R. Grace & Co., a global specialty chemicals company. In addition to managing all litigation for the company, Brian overhauled the company’s global compliance program, including enterprise risk assessment, code of conduct and policy frameworks, confidential reporting and investigations, training and communications, and third‑party due diligence. He also served as the enterprise lead for the company’s first internal e‑discovery platform and as a co-lead for its Enterprise Risk Management program, regularly briefing the C‑suite and business leadership on litigation and compliance matters.

Immediately prior to that role, Brian served as Managing In‑House Counsel (Staff Judge Advocate) for the United States Naval Criminal Investigative Service (NCIS). As lead military counsel to an organization of more than 2,000 personnel worldwide, he advised special agents on military and federal criminal law and procedure, assisted prosecutors in complex investigations, ran the agency’s federal ethics program, and led a department of military attorneys and paralegals working in close coordination with civilian agency counsel.

Earlier in his career, Brian was a partner at LeClairRyan, where he founded and led the firm’s General Counsel and Secondments practice. In that role, he provided outside general counsel services to public and private companies and litigated complex civil matters involving antitrust, government contracts, False Claims Act, intellectual property, white‑collar defense, shareholder disputes, and regulatory enforcement. He conducted and supervised numerous internal investigations and was frequently engaged to help clients resolve disputes before and during litigation.

Brian also spent more than a decade as Assistant General Counsel at Altria Group, where he counseled senior leadership across compliance, corporate affairs, communications, regulatory, and research and engineering functions. He managed nationwide litigation portfolios involving antitrust, intellectual property, commercial, anti‑counterfeiting, and regulatory matters, collaborated extensively with finance and compliance leadership, and worked closely with law enforcement and prosecutors on criminal investigations.

Brian began his civilian legal career at Arent Fox LLP in Washington, D.C., litigating commercial, intellectual property, and white‑collar matters at the trial and appellate levels for clients across a wide range of industries.

A defining aspect of Brian’s career is his 30 years of service in the United States Navy Judge Advocate General’s Corps, 11 years on active duty and 19 years in the Reserve. He served as a prosecutor, appellate defense counsel, civil litigation attorney, commanding officer, executive officer, and senior advisor to Navy leadership. He was later appointed as a military trial judge, presiding over jury and bench trials, motion hearings, and sentencing proceedings. Brian retired from the Navy in 2022 at the rank of Captain, following senior leadership service leading hundreds of Navy Reserve attorneys nationwide.

Brian has been repeatedly recognized for excellence in legal leadership and service and remains active in professional, educational, and civic organizations.
