Sidley Austin, in looking for its next chief marketing officer, took a path few top law firms have implemented but may consider in the near future for this position: two officers for the job.

In splitting the CMO role between Erin Baxendale and Kerri Vermeylen, the leadership of the Am Law 10 law firm, as well as Vermeylen and Baxendale, cited the increased responsibility of the CMO role as a driver for having two minds work the job. Sidley was ranked No. 6 in the Am Law 100 this year, with $3.1 billion in revenue.
