Complaints involving Booz Allen can relate to recruiting, workplace conduct, business ethics, procurement, contracting, data handling, supplier relationships, or interactions with company personnel. Because Booz Allen primarily operates business-to-government and business-to-business programs, the right complaint channel depends heavily on the nature of the concern.
Start with the office, recruiter, program manager, contracting representative, or employee connected to the issue. Booz Allen’s headquarters can be reached at 703-902-5000, while many regional offices have direct phone numbers. Explain the issue clearly, provide dates, names, program information, and any relevant contract or recruiting references. Keep notes and copies of written communication.
If the first contact does not resolve the matter, ask that it be reviewed by a manager, human-resources representative, contracting leader, legal team, or other appropriate department. Provide a concise chronology of the issue, previous responses, and the resolution you are seeking. For government-contract matters, retain contract identifiers, correspondence, invoices, and applicable agency contacts.
If the complaint involves suspected misconduct, ethics, conflicts of interest, fraud, procurement problems, or violations of company policy, use Booz Allen’s internal ethics and compliance process rather than ordinary office routing. Booz Allen publicly emphasizes business ethics and accountability as part of its governance framework.
For a serious unresolved corporate matter, send written correspondence to Booz Allen Hamilton, 8283 Greensboro Drive, Hamilton Building, McLean, VA 22102. Include your contact information, relevant dates, office or program details, previous complaint history, and copies of supporting records. Clearly state the action or resolution requested.
If the complaint remains unresolved, the external route depends on the issue. Federal-contract concerns may involve the contracting agency, inspector general, contracting officer, or another authorized government oversight body. Employment matters may involve relevant labor or civil-rights agencies. Securities concerns relating to the public company can involve the SEC, while legal disputes may require the applicable court, arbitration, or contractual process. Preserve all relevant documentation before escalating.
