My love for pulmonary medicine stems from the challenges that this field offers. It is a complex subspecialty of medicine that continues to push me and helps me grow as a physician. I appreciate the fast-paced environment of the Intensive Care Unit (ICU). It requires physicians to consider the patient as a whole. I also enjoy the camaraderie and teamwork of being in an ICU. I work closely with nurses, respiratory therapists, pharmacists, nutritionists and many others to care for our patients. I want my patients to feel heard and understood, and to know they are receiving the best possible care from our team.
