David A. Marcus, MD
I am a dual-boarded physician specializing in Emergency Medicine and Internal Medicine in New York City. I serve as a Clinical Ethicist and Residency Director for a combined EM/IM and Critical Care program. This site — EM IM Doc: Manifestations of the Combined Life — is where I write about the intersection of clinical practice, medical education, and ethics.
My clinical interests include bedside sonography, Critical Care, EMS, primary care, wilderness medicine, disaster and search-and-rescue medicine, and Narrative Medicine. Beyond the bedside, I focus on physician professionalism, activism, clinical ethics, health care disparities, and the social determinants of health.
Key Project: FOAM Resources — Free Open Access Medical education curated for residents, students, and practicing clinicians.

CV & Bio: Full background at David A. Marcus, MD.
The intersection of emergency medicine and internal medicine creates a unique lens through which to examine the full spectrum of patient care, from acute resuscitation to chronic disease management. This combined perspective reveals how clinical decisions made in one setting ripple across the entire healthcare continuum, challenging physicians to think beyond the immediate encounter and consider the broader narrative of each patient's life. The dual-trained physician navigates these overlapping domains daily, drawing on a deep reservoir of knowledge that spans critical care, primary care, and everything in between.
