A Message from Our Program Director
As program director, it is my honor to develop and train the next generation of physicians, researchers, and leaders in pediatric critical care medicine. Our program is dedicated to providing our fellows with a broad and intensive clinical experience, a rigorous academic curriculum, and strong foundation in research. Our training will provide the all the skills necessary to set our fellows up for a successful career wherever they choose to go after training.

Our Spaces & Places
I find immense value in the ability to work as a multidisciplinary group within the PICU. Our institution has many great minds and leaders in their respective fields. The opportunity to have an open and collegial discussion with other subspecialties regarding not only patient care but ongoing research and education has been instrumental in my growth and development as a fellow. There is a great respect for the fact that our hospital is a teaching institution on many levels and faculty take every opportunity to teach and mentor trainees.”
