Attorney General Chris Carr on Thursday announced several changes in his office’s senior leadership.

Dennis Dunn, the long-time head of the Government Operation Division of the Department of Law, has been promoted to chief deputy attorney general. Dunn replaces the retiring Jeff Milsteen, who served in the role since 1997. Dunn will serve as the attorney general’s primary legal advisor and supervise all attorney casework.

Sarah Hawkins Warren has been named solicitor general, replacing Britt Grant, whom Gov. Nathan Deal appointed to the state Supreme Court in November. Hawkins Warren will oversee appeals and collaborate on major litigation across the department.

Finally, Travis Johnson, assistant commissioner at the Technical College System of Georgia, has been named chief of staff to the attorney general. Johnson will be responsible for all operations of the office and internal and external communications and legislative affairs.

The changes are Carr's first major moves since being sworn in as attorney general on Nov. 1.

“As I’ve said before, the seriousness of this work requires focus and a readiness to tackle our state’s challenges and opportunities—and that’s what Georgians can expect from Dennis Dunn, Sarah Hawkins Warren and Travis Johnson,” Carr said.
