Munger, Tolles & Olson recorded impressive financial results in 2013, with revenue rising 16 percent, to $247.5 million, and profits per partner up 13 percent, to $1.77 million. Among the matters fueling that performance and keeping the firm’s 180 lawyers busy last year: four major trials, as well as a significant deal for key client Berkshire Hathaway.

“We were hitting on all cylinders,” says Munger Tolles managing partner Sandra Seville-Jones. “For a firm our size to be in four major trials—that stretches us and keeps us busy.”
