Locke Lord, whose lawyer head count declined in 2016, saw its gross revenue drop by 6.4 percent in 2016. But net income at the Dallas-based firm rose by 11.1 percent compared to 2015­—partly because of its booming energy practice.

“Even though commodity prices were down, there was still a lot of activity at a lot of companies,” said Locke Lord chairwoman Jerry Clements. “While in the first part of 2016, things started out slow in energy, by summer things really picked up, and by the end of the year we had really made up for the slowness at the first of the year.”
