Erin has a broad practice focused on matters arising from alleged violations of state and federal laws, including fraud, cybersecurity, public corruption, national security, workplace compliance, and issues involving board governance.

Erin has deep experience in government service having served at the highest levels of the Department of Justice as United States Attorney, and before that as an Assistant United States Attorney.

She successfully quarterbacked the Northern District of Texas’ most significant investigations, and during her tenure, the office prosecuted more cases and more defendants than any other non-border district in the nation. As U.S. Attorney, she was recognized nationally for her work in developing strategic responses to benefit the eight million residents of the North District of Texas. She was also recognized nationally and locally for her efforts to combat domestic violence through gun control initiatives and her work to eradicate human trafficking through the efforts of the North Texas Trafficking Task Force.

While serving as U.S. Attorney, she also served as Chairperson of the Attorney General’s Advisory Committee (AGAC), a body of 15 U.S. Attorneys selected by the Attorney General to advise on national priorities, including policy and operational issues. Erin also led the AGAC task force on domestic violence and firearms crimes.

Prior to her appointment as U.S. Attorney in 2017, she served briefly as a senior advisor at McKinsey & Co., in the consulting firm’s cybersecurity and risk practice.
