“When whistleblowers reach out to me, I am often the first person to tell them ‘You are right. You have uncovered a problem and are being scapegoated for it. I believe you and what’s more, the government is likely to be interested in this information.’ Erasing the self-doubt whistleblowers are made to feel when they speak up is one of the best parts of my job.“

Biography

Mary Inman is a partner at Whistleblower Partners. She has 30 years of experience representing whistleblowers in the U.S. under the False Claims Act, as well as the SEC, CFTC, IRS, FinCEN, and NHTSA/DOT whistleblower programs. After three years working in London, Mary represents an increasing number of international whistleblowers seeking to expose misconduct overseas with a nexus to the U.S. She also regularly helps whistleblowers bring claims to foreign regulators, including the Ontario Securities Commission, Canada Revenue Agency, His Majesty’s Revenue and Customs, and Korea’s National Tax Service.

Mary is a recognized expert and frequent author, commentator, and speaker on the international application of American whistleblower laws and frauds in the healthcare, tech, and financial services industries.

Mary represents Facebook Files whistleblower Frances Haugen and Theranos whistleblower Tyler Shultz and collaborated with The Signals Network and Pinterest whistleblower Ifeoma Ozoma in the creation and publication of The Tech Workers’ Handbook, a how-to guide for minimizing risks when blowing the whistle in the tech industry.

Mary is a passionate advocate for the power of whistleblowers, properly protected and incentivized, to transform and supercharge government enforcement efforts.  She has provided testimony to governments worldwide championing the success of the U.S. whistleblower programs, including the Colorado legislature in connection with the expansion of its False Claims Act, the European Commission, and UK Parliament.

Mary and her colleagues have pioneered a series of successful whistleblower cases against prominent health insurers, hospitals, provider groups, and vendors alleging manipulation of the risk scores of Medicare Advantage patients. They have become among the government’s most trusted partners in prosecuting this fraud.

Starting with a $32.7 million settlement against Florida Medicare Advantage Organization Freedom Health and its COO on behalf of her whistleblower client the late Dr. Darren Sewell, M.D., Mary has gone on to represent whistleblowers Benjamin Poehling (UnitedHealth Group), Teresa Ross (Independent Health and Group Health Cooperative) and Dr. James Taylor (Kaiser), whose cases involve allegations the Medicare Advantage Organizations submitted false claims for payment to the Medicare Program based on artificially inflated member risk scores.

Mary graduated cum laude from the University of Pennsylvania Law School in 1994, where she was an articles editor of the University of Pennsylvania Law Review.
After law school, Mary clerked for the Honorable D. Brock Hornby, U.S. District Court for the District of Maine, and the late Honorable Norman H. Stahl of the U.S. First Circuit Court of Appeals.

Before law school, Mary put her dramatic tendencies to good use as a performer at the Maine State Music Theater.

Outside work, Mary enjoys serving as gaffer, stagehand and editor for her husband’s YouTube channel Dave Fogler at the Cinodrome and, in summer, can be heard imitating loon calls on a lake in northern Maine.
