General Anesthesiology; Pediatric Anesthesiology
I am board-certified physician in both anesthesiology and pediatric anesthesiology. My main areas of clinical expertise are neonatal and pediatric anesthesia, regional anesthesia, and pediatric cardiothoracic anesthesia. While much of my clinical work has focused on caring for complex, critical infants and children, I am qualified and routinely care for patients of all ages undergoing all manner of interventions.
My academic interests are varied, but much of my work has focused on novel anesthetic techniques for neonatal and awake neurosurgical procedures, regional anesthesia in both adult and pediatric patients, and perioperative transesophageal and transthoracic echocardiography. I am also interested in incorporating point-of-care-ultrasound — performing ultrasounds at a patient’s bedside — into routine perioperative care. I routinely present my work at regional and national academic society meetings, where I also frequently teach workshops to current and future anesthesiologists.
As a lifelong learner, I try and incorporate current best practices, as well as novel anesthetic techniques to provide superb perioperative care. I also aim to treat every patient as if they were a member of my own family. I feel very fortunate to truly love what I do for a living and honored to help care for people in their time of need.

Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.
MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.
