My commitment is to the truth, not to either side.

Expert Services

 

I provide expert witness services for automobiles, recreational vehicles, and commercial trucks. My inspections and reports address mechanical failures, prior damage, fraud, diminished value, and DOT compliance. With over 30 years of hands-on experience and ASE Master Certification, I deliver fact-based, court-ready opinions. My services include failure analysis, certified appraisals, warranty dispute support, and litigation consulting for plaintiff and defense attorneys across the U.S.

I work with plaintiff attorneys, defense counsel, and court-appointed cases, always maintaining complete independence. No matter who retains me, my findings are grounded in objective evidence, OEM procedures, industry standards, and decades of diagnostic expertise.

I am not here to advocate—I’m here to clarify. My role is to provide the court with reliable, unbiased insight that supports a clear understanding of the facts and helps drive fair and informed outcomes.

Every vehicle I inspect is evaluated methodically, using a combination of hands-on diagnostics, technical data, and repair standards established by manufacturers and industry authorities. I take pride in delivering reports that are not only technically sound but also clearly written and defensible under cross-examination. Whether the case involves a single vehicle or an entire fleet, my objective remains the same: to provide honest, accurate, and fully documented expert opinions that help attorneys, judges, and juries understand exactly what happened—and why.
