Litigation involving hospital emergency preparedness, CBRN response, decontamination, hazmat operations, or mass casualty incidents requires an expert who can do more than recite standards. It requires someone who has built state-level response programs, commanded hazmat operations, trained CBRN teams, and spent decades at the intersection of clinical medicine and emergency response — and who can translate that experience into testimony that is credible, defensible, and comprehensible to a judge and jury.
David DiGregorio brings 32 years of military medical and state-level hazmat command experience, ongoing faculty work with the BIDMC/Harvard Medical School Disaster Medicine Fellowship, and direct operational expertise across emergency management, CBRN, decontamination, and mass casualty response. D2EMC accepts expert witness engagements for both plaintiff and defense counsel in matters involving hospital preparedness standards, CBRN and hazmat response, decontamination operations, emergency management practice, and mass casualty incident response.
Engagement types include expert report preparation, deposition testimony, trial testimony, report review and rebuttal, and non-testifying consulting expert roles. A conflict check is required before any privileged discussion takes place.
Your Discovery Call — Free of Charge Before we confirm any engagement, we schedule a free discovery call to understand the matter, the subject areas involved, the engagement type needed, and the timeline. A conflict check is conducted at that stage. Your quote is prepared and shared with you after the call and conflict check are complete.
What You Walk Away With Depending on the engagement type confirmed: a written expert report prepared to the standard required for your jurisdiction and matter type, deposition or trial testimony from a credentialed expert with direct operational experience in the subject matter, report review and rebuttal analysis, or ongoing non-testifying consulting support throughout the matter. Every engagement is documented and managed with the same operational discipline D2EMC brings to its clinical and preparedness work.
Best for: Plaintiff and defense counsel in litigation involving hospital preparedness standards, CBRN and hazmat response, decontamination operations, emergency management practice, and mass casualty incident response.
