Independent verification matters more in this work than marketing does. An employer choosing a consultant for a citation, an exposure investigation or an expert engagement is entitled to see who has vouched for the work. This page collects that record. The underlying reference letters and license documents are held on file and are available for inspection on request.
Full reference letters and named reviews are not published on this site. Client matters and client information are confidential, and that confidentiality is not set aside for marketing. Excerpts appear below with the writer’s initials and organization; the complete letters and the licensure documents behind them are held on file and are shown to a prospective client on request.

How to verify any of this
Ask. Copies of the reference letters summarized above are provided on request, and reference contact details are released with the reference’s permission. Nothing on this page describes a client engagement that has not been cleared for disclosure, and no client name appears here without it.
Why are the reference names shown only by initial?
Because a reference agreed to vouch for the work, not to be published in a search index. Initials preserve the substance while keeping the individual’s name off a public page. Full names and contact details are supplied directly to a prospective client, with the reference’s permission.
Can I speak to a past client before engaging the company?
Yes. Tell us the kind of matter you are facing — a Cal/OSHA citation, an exposure assessment, an injury investigation, an expert engagement — and we will put you in touch with a reference whose situation resembled yours.
