Choate Adds Former Assistant U.S. Attorney Diane Seol to Government Enforcement Practice
"Choate has hired former Assistant U.S. Attorney Diane Seol as of counsel in its Government Enforcement, Investigations and Compliance practice, focusing on healthcare False Claims Act and Anti‑Kickback matters."
Seol returns to Choate after more than four years serving as an Assistant United States Attorney in the Affirmative Civil Enforcement Unit of the U.S. Attorney’s Office for the District of Massachusetts. In that role she focused on pursuing alleged violations of the federal False Claims Act and the Anti‑Kickback Statute and was involved in numerous high‑profile healthcare FCA matters, including lawsuits and settlements with pharmaceutical manufacturers and distributors. Her matters included allegations concerning Medicare co‑pay assistance manipulation, fraudulent drug price reporting, false Medicare reimbursements for medically unnecessary services, fraud under the Paycheck Protection Program, and violations of Section 8 housing program requirements by landlords.
Prior to her service at the U.S. Attorney’s Office, Seol spent seven years at Choate representing life sciences, pharmaceutical, and technology companies in internal and government investigations and intellectual property litigation. During that period she completed Choate’s rotational DA’s office program and served as a Special Assistant District Attorney in the Suffolk County District Attorney’s Office, prosecuting criminal matters on behalf of the Commonwealth of Massachusetts.
Seol holds a J.D. from Columbia Law School and a B.A. from Wellesley College and is admitted to practice in Massachusetts and New York.
