About this doctor:

In addition to his regular duties in the Department of Surgery, Dr. Preston also maintains responsibilities in the Department of Emergency Medicine by participating in internal Grand Rounds, external Continuing Medical Education courses, assisting with bedside teaching of our house-staff and medical students with regards to care of the trauma patient and also participating in and contributing to the emergency medicine research program.

Dr. Preston is an excellent critical care intensivist and educator who takes particular pride in being a superbly reliable practitioner/peer and an effective ICU manager. He has a profound fund of knowledge that is kept current by continual review and application of recent findings presented in journals and society proceedings and heartily welcomes discussion and input from colleagues on challenging cases. Dr. Preston’s strong commitment to a multidisciplinary approach in providing critical care fits in seamlessly with the team approach practiced among our trauma division faculty. Through Dr. Preston’s knowledge, approachableness and keen interest in ongoing research in the area of ventilator-associated pneumonia prevention, our trauma residents and fellows undoubtedly foster their own growth and mastery of trauma and critical-care medicine and together continue to provide the utmost excellence in care for their patients.
