Technical Credibility That Holds Up Under Cross-Examination
An expert witness is only as valuable as their credibility. Michael McNeil's 35+ years of hands-on California safety consulting — not academic theory — gives him the practical authority that holds up under aggressive cross-examination. He has worked directly with Cal/OSHA, conducted hundreds of workplace inspections, and written safety programs for employers across every major California industry.
For cases involving healthcare facilities, infection control, or occupational illness, our Licensed Nurse brings clinical expertise that no purely safety-focused consultant can match. This combination of occupational safety and clinical nursing credentials is unique in California expert witness practice.
Common Questions from Attorneys
What types of cases does McNeil Safety Consulting support?
We provide expert witness and litigation support for workplace injury and wrongful death cases, Cal/OSHA citation appeals and enforcement actions, workers' compensation disputes involving safety standard violations, premises liability cases involving workplace hazards, and civil litigation arising from occupational illness or toxic exposure. We work with both plaintiff and defense counsel, as well as insurance carriers and risk management teams.
What qualifications does Michael McNeil have as an expert witness?
Michael McNeil has over 35 years of direct experience in California occupational health and safety — including Cal/OSHA compliance, industrial hygiene, infection control, and environmental assessment. He holds professional credentials in occupational safety and health, and McNeil Safety Consulting has a Licensed Nurse on staff for cases involving occupational illness, infection control, and healthcare facility standards. He has provided expert testimony in California courts and administrative proceedings.
Can you serve as an expert witness for both plaintiff and defense?
Yes. We work with both plaintiff attorneys and defense counsel, as well as insurance carriers and self-insured employers. Our role is to provide objective, technically accurate analysis of the safety standards applicable to the case and whether those standards were met. Our credibility as an expert depends on our objectivity — we do not advocate for outcomes, we analyze facts.
What does a litigation support engagement typically involve?
A typical engagement begins with a case review — we analyze the incident reports, Cal/OSHA investigation records, medical records, site photographs, and any available safety documentation. We then prepare a written technical analysis identifying the applicable Cal/OSHA standards, whether they were violated, and the causal relationship between any violations and the injury or illness. If retained as a testifying expert, we prepare a formal expert report and are available for deposition and trial testimony.
How quickly can you review a case?
We understand that litigation has deadlines. We can typically complete an initial case review and provide a preliminary opinion within 2–5 business days of receiving the relevant documents. For urgent matters — including cases approaching deposition or trial — call us directly at (626) 546-9384 to discuss expedited review.
Do you provide support for Cal/OSHA administrative proceedings?
Yes. We provide technical support for Cal/OSHA Appeals Board proceedings, including case analysis, preparation of technical arguments, and expert testimony before administrative law judges. We are familiar with the Cal/OSHA Appeals Board process and understand how to present technical safety arguments effectively in that forum.
