Robert Nichols may have walked away from a big legal industry name when he left Covington & Burling last year, but he was careful not to leave too much else behind.

The government contracts lawyer—who debuted his new firm, Nichols Liu, earlier this week—said he took his entire client roster and a “decent” book of business with him when he departed Covington in November. He’s spent the months since assembling a group of lawyers and planning an internal firm management structure specific to his venture.
