I have dedicated my life’s work to the surgical treatment of children with brain and spinal disorders. I am internationally recognized for my deep experience in challenging surgeries. These include removing tumors near the spine and in the ventricles of the brain (called intraventricular brain tumors); managing tumors in the pineal gland, also in the brain; treating congenital cysts, which are present in the body at birth; and correcting Chiari malformation, a condition in which tissue from the brain extends into the spinal canal. I perform about 300 surgeries each year; many of them are minimally invasive. For general information, call Memorial Sloan Kettering at 212-639-2000, 24 hours a day, seven days a week.
