Maggie Carter is a skilled trial attorney and former federal prosecutor who specializes in high-stakes civil and white collar criminal trials, complex litigation, sensitive internal investigations and regulatory matters. Her extensive government experience includes the prosecution of complex financial fraud, civil rights, and public corruption cases. Maggie’s industry experience is broad—she has represented companies and individuals in the investment funds, entertainment, financial services, health care, technology, education, and telecommunications industries in criminal, civil, and investigations matters.  Maggie also represents a large public entity on immigration issues and has filed numerous amicus briefs to further the entity’s support of immigrant residents and local law enforcement priorities.

In addition to her practice, Maggie dedicates significant time to pro bono advocacy and community involvement. Together with the ACLU of Nevada, the ACLU National Federation, and the former Federal Public Defender in Las Vegas, she recently spearheaded a civil rights class action against the State of Nevada and Governor to challenge how the State of Nevada provides criminal defense services to indigent defendants. Maggie also serves as co-chair of the firm’s Trial Advocacy Prosecution Program, which trains associates to prosecute misdemeanor crimes in California’s Redondo Beach, allowing the small city to take on special projects it otherwise might not have the resources to handle.

Maggie serves on the board of the Western Center on Law & Poverty and helps to drive the organization’s mission to advocate for low-income Californians. She also serves on the board of Radio Bilingüe, Inc. and the Women Lawyers Association of Los Angeles, and on the Los Angeles County Bar Associate Litigation Section Executive Committee.

Maggie spent eight years as a prosecutor in the United States Attorney’s Office for the Central District of California, where she focused on public corruption, civil rights, and sophisticated fraud cases, including those involving charges of embezzlement, money laundering, health care fraud, and identity theft. Maggie conducted a sweeping investigation of the largest sheriff’s department in the United States, which has resulted in the convictions of the former Sheriff and Undersheriff, and 19 other current and former officers. She has also served on the Department of Justice Medicare Fraud Strike Force and as Identity Theft Coordinator. Maggie has worked closely with regulators from federal agencies including the FBI, IRS, the Department of Health and Human Services, the Department of Labor, and the Department of Homeland Security.

Before becoming a lawyer, Maggie was a management consultant at McKinsey & Company, where she specialized in growth strategy, primarily in the energy and technology sectors.
