Litigation Support & Expert Witness
When a workplace violence or security negligence matter reaches litigation, the quality of the expert opinion is often dispositive. We provide written opinions, declarations, and testimony grounded in documented methodology — WAVR-21, recognized security program standards, and operational experience that survives cross-examination.
— The difference
Expert opinions are only as strong as the methodology and credentials behind them. We use the same structured assessment framework trusted by Fortune 500 threat assessment teams and government protective intelligence programs — and our principals have operational backgrounds that no career consultant can match in a courtroom.
— Overview
Workplace violence litigation — negligent security, failure to warn, premises liability, wrongful death — turns on the standard of care. What was the employer required to do? What did they actually do? Was the gap between those two things the proximate cause of the harm? Answering those questions credibly requires an expert whose methodology is documented, whose credentials are legitimate, and whose opinion will hold up under aggressive cross-examination.
Kestralis Group provides expert witness services in matters involving workplace violence prevention program adequacy, behavioral threat assessment methodology and its application to specific facts, physical security standard of care, and the organizational response to warning signs. Our principals bring a combination of operational experience, enterprise security program leadership, and documented professional credentials that is rare in the expert witness community — most experts in this space come from either a law enforcement background or an academic one. Ours come from both operating environments and the boardroom.
We also provide pre-litigation support for matters that have not yet reached formal proceedings — reviewing incident reports and internal investigations, assessing the defensibility of an organization's existing programs, and advising counsel on the likely expert opinions they will face from opposing parties. Early engagement allows counsel to understand the evidentiary landscape before discovery shapes it.
— How we work
The engagement from first call to final deliverable.
Four phases · scoped individually to the client
- Phase 01
Initial Case Review
We review the core case materials — incident reports, internal investigation documents, the organization's existing programs and policies, and the specific allegations — and provide counsel with a preliminary assessment of the evidentiary landscape. This is typically a flat-fee engagement that tells counsel whether a formal expert retention makes sense and on what issues.
- Phase 02
Formal Retention & Discovery
Formal expert retention is structured through counsel. We provide a formal retention agreement, an initial disclosures-compliant CV, and a fee schedule. We participate in the discovery process as directed by counsel — reviewing produced documents, responding to interrogatories related to expert opinion, and identifying the materials we need for a complete opinion.
- Phase 03
Opinion Development
We develop the expert opinion through a documented analytical process — applying recognized standards (ASIS WVPI-AA-2020, NFPA 1600, WAVR-21) to the specific facts of the case. The written report documents methodology, materials reviewed, and opinions in the format required by applicable rules of civil procedure. We work with counsel through drafts to ensure the opinion is clear and complete.
- Phase 04
Testimony
We prepare for deposition and trial through a structured preparation process with counsel — reviewing likely cross-examination lines, clarifying the technical content of the opinion for a lay audience, and ensuring the testimony is consistent with and supported by the written report. We are available for both deposition and trial testimony.

— Common questions
What clients ask before they engage.
What types of matters do you accept as an expert?
We accept expert engagements in workplace violence prevention program adequacy, behavioral threat assessment methodology and application, physical security standard of care, threat recognition and response obligations, and organizational response to employee warning signs. We do not provide opinions in areas outside our documented expertise, and we do not provide opinions we do not hold — our credibility on cross-examination depends on the integrity of what we say.
Which side do you work for — plaintiff or defense?
Both. We evaluate each matter on its facts and provide our honest opinion about what the evidence shows. An expert who only works for plaintiffs or only works for defendants is a hired gun, not a credible witness. Our opinions are consistent regardless of which side retains us, which means they are more likely to hold up in the proceedings that matter.
What credentials qualify you to testify as a workplace violence expert?
Our principals bring a combination of Special Operations military service, enterprise security program leadership at Fortune-scale organizations, CBCP certification, WAVR-21 practitioner training, and licensed investigative experience. We have designed and managed the programs that are the subject of standard-of-care disputes — not just studied them. That combination is difficult to cross-examine because it is grounded in operational reality rather than academic theory.
Can you review and rebut an opposing expert's opinion?
Yes. Opposing expert rebuttal is a significant part of what we do. We review the opposing opinion, assess its methodology and factual basis, identify weaknesses and overstatements, and provide counsel with both a written rebuttal and a preparation framework for cross-examination of the opposing witness.
How early in a matter should we engage you?
As early as possible. Pre-litigation engagement — before discovery is shaped, before positions are taken, before the organization has committed to a defense theory — allows us to give counsel the most useful assessment of the evidentiary landscape. We frequently review an organization's program before a matter is formally filed and identify both strengths to emphasize and weaknesses to address.
