Overview

Sharmi Das’ experience at the Department of Homeland Security (DHS), Department of Justice (DOJ), the White House, the U.S. Senate, and private practice positions her to guide clients through regulatory challenges, government-facing issues, and scrutiny from Congress and other oversight bodies. Sharmi has handled dozens of congressional inquiries and managed a program that developed hundreds of regulatory actions relating to homeland security matters, including technology, cybersecurity, contracts and grants, intelligence, health, and immigration. She participated in hundreds of policy discussions at the White House and DHS on high-profile issues that were often in the headlines, including domestic and international crises and emergencies.

Sharmi was awarded the Distinguished Service Medal by the Secretary of Homeland Security for exceptional service, the Department’s highest civilian honor.

Sharmi values public service and maintains a diverse pro bono practice, including her time seconded to the Legal Aid Society of the District of Columbia.
