About Me

I am a pediatric surgeon and Chief of the Pediatric Surgical Service at Memorial Sloan Kettering. I have dedicated my life to caring for children, particularly those with cancer. I take care of children and teenagers with many types of tumors and malignancies, and perform about 200 surgeries each year.

I have been a pediatric surgeon for nearly two decades. In those years, I have developed new methods to make surgical procedures more predictable and straightforward for various cancers. I prefer a team approach in the operating room. Working with a group of highly skilled surgeons, anesthesiologists, nurses, and other experts allows for the best possible outcomes.

I am very excited to continue my research in high-intensity focused ultrasound (HIFU) at MSK. This noninvasive procedure uses sound waves to pinpoint a tumor and destroy it. HIFU has the potential to offer another treatment option for children who have tumors that cannot be removed through surgery. My hope is that in time, fewer children will need surgery. This treatment could reduce surgical complications and improve overall survival, especially for children whose cancers have returned.

When I meet a child with cancer, I aim to present the situation and how we are going to approach it as clearly as possible. Families deserve a considerable amount of time to digest all the new information coming their way. I am happy to speak with them as many times as it takes for everyone to understand the plan and feel confident about it. And when a child is old enough to understand what is going on, it is important to involve them in the decision-making as much as possible. I recognize the tremendous level of trust that families place in us. It is very important to me that everyone feels comfortable and that they feel that they are in the best of hands.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicare and New York State Medicaid also provide benefits for care at MSK.
