Susie Lees is drawing upon her quarter-century experience in the in-house legal department at The Allstate Corp. to overhaul the department she took over in 2012 — and it’s working.

Lees takes a big-picture perspective at the insurance giant, where she’s taken apart and redesigned a 656-lawyer, 1,300-employee team. “By putting some larger blocks of work together, we opened up the opportunity for cross-training and development of our lawyers,” said Lees, who also serves as executive vice president and secretary of the $34.5 billion company.
