Linda C. Severin

"I love practicing law because it engages my mind in analyzing complex issues, my heart in understanding the hopes and fears of my clients, and my voice in advocating for justice."

Linda Severin has decades of experience in criminal and civil enforcement actions, investigations, and complex litigation. Her background as a federal prosecutor, a white-collar defense attorney, and an in-house litigation attorney at a Fortune 100 corporation enables her to analyze whistleblower fraud matters from multiple perspectives.

Ms. Severin became a member of the Whistleblower Law Collaborative in 2018. Before joining the firm full-time, she had been a solo practitioner working on False Claims Act matters with Bob Thomas and Suzanne Durrell, most notably United States ex rel. Westmoreland v. Amgen, Inc., 707 F. Supp. 2d 123 (D. Mass. 2010), which was part of the global criminal and civil settlement against Amgen.

Linda C. Severin served for eight years as an Assistant U.S. Attorney in the Southern District of New York. As a federal prosecutor, she investigated and tried cases involving fraud, racketeering, drug trafficking, money laundering, and extortion, and she briefed and argued criminal appeals before the Second Circuit Court of Appeals. Her supervisory positions included Deputy Chief of the Appeals Unit, Deputy Chief and Acting Chief of the Narcotics Unit, and Chief of the New York/New Jersey Organized Crime Drug Enforcement Task Force.

From my first meeting with Linda, I knew I had found the best attorney to represent me. Though I was inexperienced with the process, she guided me through with professionalism, integrity and caring. I cannot recommend her strongly enough.

Before joining the U.S. Attorney’s Office, Ms. Severin was a law clerk to the Honorable John E. Sprizzo, District Judge for the Southern District of New York, and a litigation associate at Curtis, Mallet-Prevost, Colt & Mosle. While at Curtis, Mallet-Prevost, she was part of a trial team that successfully represented plaintiffs suing Standard Oil Company and Amoco for damages caused by the grounding of the Amoco Cadiz oil tanker off the coast of France.

After leaving the U.S. Attorney’s Office, Linda Severin moved to Seattle and entered private practice, where her work focused on white-collar criminal defense and internal investigations. She was a partner at Bogle & Gates and later founded the firm of Tallman & Severin LLP with Richard C. Tallman. After Mr. Tallman became a United States Judge for the Ninth Circuit Court of Appeals, Linda worked in-house for The Boeing Company and, later, for Garvey Schubert Barer.

Ms. Severin taught trial advocacy as an adjunct instructor at both the University of Washington Law School and New York Law School. In Seattle, she was a member of the Criminal Justice Act panel for the Western District of Washington, representing indigent criminal defendants in federal court. She also was part of a team of pro bono attorneys representing clients who successfully challenged Washington State ballot initiatives seeking to restrict civil rights for LGBTQ persons. Linda C. Severin has been a frequent speaker at continuing legal education programs and other legal conferences.
