Marilyn McCullum,
BSN, RN, CEN, CPEN, TCRN
I’m a US- and NZ-licensed emergency/trauma nurse with triple board-certification (CEN, CPEN, TCRN).
I consult for both plaintiff and defense, providing strictly neutral, evidence-based opinions anchored to the nursing standard of care.
My background includes frontline ED practice across multiple systems, peer-reviewed publications, and frequent public speaking.
​
I also contract as a Subject Matter Expert for HealthStream, a US-based company that provides online education, competency assessment, and workforce development solutions for healthcare professionals and organizations.
Attorney (Defense, CA):
“Marilyn’s report dissected a decade of records into a timeline that changed how we approached mediation. Her attention to policy standards is unmatched.”
Plaintiff Attorney (IL):
“Her analysis clarified breaches that our medical expert later used to anchor testimony. We settled shortly after disclosure.”
Defense Counsel (NV):
“We brought her in late in discovery and she turned around a robust standards opinion in under ten days—concise, neutral, and completely defensible.”
Plaintiff Attorney (TN):
“She communicates like a clinician and a consultant rolled into one. The jury prep session saved us hours.”
