Andrew Tisser, DOEmergency Medicine Expert Witness
Services

From merit screen to trial testimony.

Every engagement is scoped to what the matter actually requires. Nothing is padded, and the honest assessment comes first.

Case Screening & Merit Review

Before you invest in a case, an early and candid read on whether the emergency care fell below the standard of care. If the medicine does not support the claim, you will hear that directly.

  • Verbal merit assessment
  • Key issues identified
  • Honest go / no-go guidance

Medical Record Analysis

A complete, chronological review of the chart (triage, nursing documentation, physician notes, orders, imaging, labs, timestamps, consults, and disposition), reconstructing what was known and when.

  • Full timeline reconstruction
  • Documentation gap analysis
  • Standard-of-care assessment

Written Expert Reports

Clear, well-organized reports that state the applicable standard of care, the relevant facts, and the reasoning that connects them, written to withstand opposing scrutiny.

  • Rule-compliant reports
  • Clearly stated opinions
  • Cited clinical reasoning

Deposition Testimony

Prepared, measured deposition testimony that stays anchored to the record and does not overreach, the kind that holds up when tested.

  • Thorough preparation
  • Composed under cross
  • Consistent with the report

Trial Testimony

Testimony that translates complex emergency medicine into plain, credible language a jury can follow, authoritative without being condescending.

  • Jury-ready explanations
  • Demonstrative support
  • Calm, credible delivery

Standard-of-Care Consultation

Ongoing consultation on emergency department decision-making, triage, disposition, documentation, EMTALA, APP supervision, and systems-level issues throughout the life of the case.

  • Strategy support
  • Deposition question prep
  • Rebuttal analysis
Why It Holds Up

Clear, objective opinions designed to withstand careful scrutiny.

Credibility is the whole point. An opinion that cannot withstand scrutiny is worth nothing to your case.

Anchored to the record

Every opinion traces back to a specific fact, note, or timestamp in the chart.

Standard of care at the time

Care is judged on the information available then, not with hindsight.

No overreach

Opinions stay within emergency medicine and within what the evidence supports.

Consistent throughout

Report, deposition, and trial testimony tell one coherent story.
