Government Experience, Bespoke Advocacy in Healthcare Litigation
Overview
AGG has assembled one of the deepest benches of high-ranking former government attorneys in the industry, bringing their unique government insights, contacts, and skills to bear for our clients, whether it’s defending or going on the offensive in healthcare litigation matters involving federal agencies. AGG’s Healthcare Litigation team includes former senior attorneys from the U.S. Department of Justice, the Department of Health and Human Services, the Office of Inspector General, and the Centers for Medicare & Medicaid Services, offering clients the strategic advantage of firsthand agency insight. We understand how enforcement decisions are made, how regulatory disputes unfold, and what arguments resonate with the government — because we’ve made them ourselves.
Our clients often face scrutiny from the same agencies we once served. Whether the matter involves False Claims Act allegations, OIG subpoenas, CMS recoupments, or state-level Medicaid actions, our attorneys deliver informed advocacy that anticipates regulator behavior and reduces exposure.
AGG’s former federal attorneys have held pivotal roles in government:
- David Blank: Former Senior Counsel at the Office of Inspector General, U.S. Department of Health and Human Services
- Aaron Danzig: Former Assistant United States Attorney in the U.S. Attorney’s Office for the Northern District of Georgia
- Sara Lord: Former Trial Attorney and Senior Litigation Counsel at the U.S. Department of Justice Criminal Division; Former Assistant United States Attorney and Healthcare Fraud Coordinator in the U.S. Attorney’s Office for the Northern District of New York

- Andrew Tsui: Former Litigation Counsel at the U.S. Department of Health and Human Services, Office of the General Counsel, Centers for Medicare & Medicaid Services Division
- Kevin Lake: Former Attorney at National Complex Litigation and Investigation Division, U.S. Department of Health and Human Services
These backgrounds provide clients with fluency across the enforcement and reimbursement lifecycle.
