About Me
As a non-invasive cardiologist at NYU Langone, I am dedicated to delivering comprehensive care that prioritizes the wellbeing of my patients. I find immense satisfaction in truly listening to my patients, understanding their goals, and guiding them through personalized treatment plans.
I specialize in preventive cardiology, echocardiography, cardiac imaging, and cardiac risk stratification. My clinical interests also include managing hypertension, coronary artery disease, arrhythmias, and heart failure. With extensive training in advanced cardiac imaging, I utilize the latest technologies to provide accurate diagnoses and effective treatment plans for complex heart conditions.
Throughout my career, I have gained significant experience in both clinical practice and advanced cardiac imaging. My residency in internal medicine at Harvard Medical School鈥檚 Beth Israel Deaconess Medical Center and my fellowship in cardiovascular medicine at NYU Langone have equipped me with the skills and knowledge to manage a wide range of cardiovascular conditions. I am board certified in internal medicine, cardiovascular medicine, echocardiography, and cardiac nuclear imaging, and I am a fellow of the American College of Cardiology.
My journey into medicine began with a unique background in piano performance, which fostered a deep appreciation for rhythm and sound. This early fascination with the rhythmic and acoustic patterns of the heart ultimately led me to pursue a career in cardiology. My training and experiences have shaped my commitment to providing exceptional care, and I am proud to be part of the NYU Langone team, where I collaborate with colleagues to ensure coordinated and seamless care for my patients.
