How I Work

I take engagements where I can offer an honest, independent opinion — not a predetermined conclusion. If the surveying evidence doesn't support your position, I'll tell you early so you can make informed decisions about your case.
Independence first My opinions are based on evidence and professional standards, not advocacy goals.
Scope that fits the matter Not every case needs a full report. Some need a phone call. I'll tell you which.
Clarity under cross-examination Complex surveying concepts explained in plain language that holds up in the courtroom.
Complimentary initial consultation 30 minutes to evaluate your matter before any commitment on either side.
