Chair, Department of Emergency Medicine

The UT Southwestern Department of Emergency Medicine was founded to provide the highest level of care to all who need it, and we are privileged to have the opportunity to serve a diverse group of patients. Whether it’s in our own Clements University Hospital or at our teaching hospitals – Parkland Memorial Hospital and Children’s Medical Center – we deliver quality care to millions annually.

Our Mission

Our department aspires to advance the UT Southwestern Medical Center tripartite mission: 

  • Educate physicians, scientists, and caregivers optimally prepared to serve the needs of patients and society
  • Discover research that solves for unmet needs by finding better treatments, cures, and prevention with a commitment to ensuring real world application
  • Heal best care possible today, with continuous improvement and innovation for better care tomorrow

These missions drive us to continuously advance our education efforts, be innovative in our approach to clinical care, and identify the many areas we can serve our community. 

Commitment to Diversity and Excellence

The Department of Emergency Medicine fosters excellence in health care delivery, education, innovation, and discovery by recognizing the uniqueness in our patients, faculty, trainees, and staff.  We are proud of the expertise of our faculty and are fortunate to have nationally-recognized leaders in:

  • Advocacy
  • Emergency medical services
  • Education
  • Disaster management
  • Toxicology
  • Simulation
  • Ultrasound
  • Research

Additionally, our faculty includes past national presidents of the American College of Emergency Physicians and the Society of Academic Emergency Medicine.

The multifaceted expertise of our Department’s faculty allows us to offer unparalleled fellowships in many of the key specialties of emergency medicine. 

Emergency Medicine Residency Program

"Everything is bigger and better in Texas,” and the same rings true for our residency. As one of the largest three-year emergency medicine residency programs in the United States, our program recruits residents from all over the world. With a commitment to excellence, our residents receive advanced training that provides them with real-life experiences to become well rounded and clinically competent providers.
