Former U.S. Attorney David R. Dugas will remain in Baton Rouge to head a New Orleans-based law firm’s nationwide energy practice, officials announced Tuesday.

Dugas, who resigned his federal post last week, will join McGlinchey Stafford on May 1, the law firm said in a press release.

In addition to chairing the firm’s energy practice, Dugas will serve as co-chair of McGlinchey Stafford’s governmental investigations team.

“We are honored to have David join our team and are excited to offer his distinguished level of expertise to our clients,” Rudy Aguilar, the law firm’s managing member, said in a written statement.

Dugas was a private-practice attorney who focused on oil-and-gas litigation as well as environmental issues prior to serving more than eight years as U.S. attorney for the Middle District of Louisiana.

The 1978 graduate of LSU’s Paul M. Hebert Law Center was appointed to his federal post by former President George W. Bush.

In addition to New Orleans and Baton Rouge, McGlinchey Stafford has offices in Dallas, Houston, Cleveland, Monroe, Jackson, Miss., and Albany, N.Y.
