EM-Sim is an AI-powered clinical simulation platform built by an emergency medicine physician for emergency medicine physicians and residents. We believe that deliberate practice with realistic scenarios is the key to sharper clinical decision-making when it matters most.
To provide emergency medicine physicians and residents with realistic, evidence-based simulation training — accessible anytime, anywhere.
Emergency departments are high-stakes environments where clinical decisions must be made rapidly and accurately. EM-Sim bridges the gap between textbook knowledge and real-world practice by immersing learners in branching clinical scenarios that mirror the complexity and urgency of the emergency department.
A future where every emergency medicine physician has access to continuous, personalized simulation training that evolves with the latest clinical evidence.
We envision EM-Sim as the standard for supplemental emergency medicine education — a platform that residency programs, attending physicians, and medical students rely on to maintain clinical sharpness, prepare for board examinations, and ultimately deliver better patient outcomes.
Every feature and scenario in EM-Sim is guided by these core principles.
Every scenario is grounded in explicitly versioned, evidence-based guidelines and reviewed for clinical fidelity.
Branching decision trees and immediate feedback promote the kind of focused repetition that builds clinical expertise.
Built by an emergency physician who understands the demands of the ED and the realities of residency training.
Sharper physicians save more lives. Everything we build is ultimately in service of the patients who depend on emergency care.
EM-Sim is designed for every stage of emergency medicine training — from medical school to attending practice.
Build a strong foundation in emergency medicine clinical reasoning before entering residency. Practice the decision-making process in a safe, guided environment.
Supplement your clinical rotations with targeted simulation practice. Prepare for ABEM board examinations with realistic case-based scenarios across all major emergency medicine categories.
Stay sharp between shifts. Review high-acuity scenarios, explore rare presentations, and maintain the clinical edge that comes from consistent practice.
EM-Sim is not a question bank or a passive video library. It is an active simulation platform where every decision you make shapes the clinical outcome — just like in a real emergency department.
EM-Sim was created by a physician who has spent his career teaching at the bedside.
Dr. Shermer is a board-certified emergency medicine physician whose career spans high-volume emergency departments, HEMS medical direction, and service as an Army National Guard State Surgeon. Throughout his career, he has been deeply committed to medical education — mentoring residents, teaching medical students at the bedside, and developing innovative approaches to clinical training.
His passion for teaching is matched by a genuine belief that simulation-based education can transform how emergency physicians prepare for the most critical moments of their careers. Dr. Shermer founded EM-Sim to bring the same hands-on, case-based teaching style he uses at the bedside into a platform that physicians can access anytime, anywhere.
