A Bureau Chief (sometimes known as a Unit Chief), is a title given to senior management in a district attorney's office. They manage specilized bureaus and units that prosecute and investigate specific crimes. These people usually report directly to the Executive assistant district attorney who heads the division they report to. The exact roles and job assignments for each title vary with each individual office, but generally include management of the daily activities within the office. In addition to the Assistant District Attorneys working for them they also have a deputy who helps manage personnel and their cases.
