About Me
As a pediatric emergency medicine specialist at NYU Langone, I provide compassionate and comprehensive care to children in critical need. My journey into pediatric care began with teaching and coaching swimming, where I developed a deep appreciation for the unique needs of children and how to connect with them. This early experience inspired me to pursue a career in medicine, where I could make a significant impact on young lives.
I specialize in pediatric emergency medicine, focusing on improving the care of febrile neonates, enhancing pain management in emergency settings, and addressing pediatric mental health issues. With a master of public health (MPH) from the Columbia University Mailman School of Public Health and a residency in pediatrics at Maimonides Medical Center, I bring a wealth of knowledge and experience to my practice. My years of training and dedication to pediatric care have equipped me with the skills necessary to handle the most urgent and complex cases.
Throughout my career, I have been committed to proactive healthcare engagement and patient education. I strive to empower families with knowledge and support, ensuring they feel informed and cared for during challenging times. My work extends beyond clinical practice; I am a prolific contributor to medical literature, authoring several peer-reviewed publications on critical topics such as serious bacterial infections in young infants. Additionally, I am passionate about mentoring medical students and residents, actively developing curricula and resources to improve medical education.
My educational journey began with a deep-seated passion for public health and pediatrics. After earning my MPH, I knew that a career in pediatric emergency medicine was my calling. At NYU Langone, I am proud to be part of a dedicated team providing coordinated and seamless care for our young patients. My goal is to build trust and rapport with my patients and their families, ensuring they receive the highest quality care.
