McGuireWoods is shoring up its environmental practice in the capital, bringing on three new partners Wednesday who have experience taming regulators and litigating environmental matters up to the U.S. Supreme Court level.

Makram Jaber, Allison Wood and Aaron Flynn are joining as partners in Washington, D.C., where they’ll contribute to the firm’s regulatory and compliance department and energy enforcement practices. The trio join from Hunton Andrews Kurth, where Jaber and Wood had practiced together since 1999 and Flynn had been since 2007.
