Philosophy of Care

For me, being a pediatric cardiologist is a dream job. I realized during my time in college that this field perfectly combined my interest in Engineering (after all, the human heart works basically as a battery and a pump) with my affinity for the intensely personal relationships formed between a physician and his patient.  I try to bring my awareness of the importance of this combination to bear in my daily interactions with my patients, by recognizing that the style with which I communicate with them is just as important as the rigor of the science that I bring to bear in diagnosing and treating their (or their children’s) heart problems. Moreover, I strive to treat each patient with the high degree of respect and compassion that I feel that everyone who comes through the doors of Boston Children’s Hospital deserves.


In my work at Boston Children’s Hospital, I feel that I have come full circle.  I was born and grew up in Massachusetts, not far from Boston. After moving to New Hampshire to attend Dartmouth College, I embraced the field of Engineering, but also became intrigued by the Biological Sciences. It was then natural for me to enroll in a PhD program in Biomedical Engineering at my next destination, Duke University. My fascination with Biology continued, leading me towards the MD program at Duke. After finishing my MD/PhD there, I moved on to San Francisco for my pediatric residency at the University of California.  After 3 wonderful years, I applied to the Fellowship program in Pediatric Cardiology at the best program in the country, Boston Children’s Hospital.  Thrilled to have been given a spot, I spent 3 years here for my traditional fellowship then another year pursuing advanced training in Pediatric and Fetal Imaging.  Offered the opportunity to stay on as faculty, I jumped at the chance.  Since that time, I have continued to develop a strong clinical interest in fetal and pediatric cardiology, with a particular focus in imaging.  My research interests surround the development of novel ultrasound-based methods to characterize cardiac structure and function within pediatric cardiology.
