Auditor search

Below is a list of all currently certified, previously certified, decertified, suspended, and restricted auditors. Auditor searches can be customized by location and certification status.

Each PREA audit must have one lead DOJ-certified PREA auditor who is responsible for the conduct of the audit and all work products. A lead auditor can employ other DOJ-certified PREA auditors to function as secondary auditors or support staff who are not DOJ-certified auditors. However, it is important to know that auditors who have been decertified or who are on suspension may not participate in PREA audits, nor as an agent of a PREA auditor. (See 34 U.S.C. §30307(e)(8)(B)(i).) An auditor with 'Restricted' status may need permission from the DOJ PREA Management Office to initiate new PREA audits or complete PREA audits in progress.

Agencies and facilities, as well as DOJ-certified PREA auditors seeking audit support staff, are strongly encouraged to check the list for the names of auditors who have been decertified and auditors who are suspended, to ensure that the selected auditor and support staff employed by the auditor are eligible.

Note that auditors who voluntarily surrendered their certification or were not recertified when their three-year certification expired are still eligible to participate in an audit as an agent of a DOJ-certified PREA auditor.

Auditors submitted the bio information located below. The PRC posted only those bios from certified auditors who consented, and made only minor spelling, punctuation, and grammar corrections.
