Why I Treat Children

Taking care of children brings joy to my job every day. My patients always bring a positive outlook and unlimited energy! I enjoy helping children and their families understand their cardiac conditions and the treatment options available and helping them navigate through their illness.

What I'm Passionate About

I am passionate about helping families understand cardiac anatomy and physiology as it pertains to their child. I enjoy taking care of patients from fetal life through adulthood, using my expertise in cardiac genetics and cardiac imaging to better understand their conditions, and help anticipate the course of treatment. My specific interests in cardiology are: Cardiac imaging including fetal echocardiography, transthoracic and transesophageal echocardiography Cardiac MRI and CT Cardiovascular genetics
