While diving oil prices took a bite of many Texas law firms energy practice wallets, that hardly seemed to matter to Dallas’ Gardere Wynne Sewell, which brought in $149 million in gross revenue during their recently completed fiscal year—an increase 4.2 percent over the $143 million from the previous year.

“We’re a busy energy firm. I would have anticipated some issues because of oil prices. But we didn’t experience that. Clients saw this as a time to acquire,” said Holland N. O’Neil, chair of Gardere’s board of directors, about the firm’s performance during its 2015 fiscal year, which concluded March 31.
