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 Excellence

The Department of Emergency Medicine fosters excellence in healthcare 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:

  • Education
  • Disaster management
  • Toxicology
  • Simulation
  • Ultrasound
