Overview of Dr. Greenfield
Dr. Greenfield is a board-certified neurosurgeon who specializes in pediatric neurosurgery; he also sees adult patients with certain neurosurgical conditions. He has a special interest in minimally invasive endoscopic approaches that are less traumatic than traditional surgery for his young patients and their families. He directs the pediatric skull base surgery, epilepsy surgery, and spasticity surgery programs, and is the co-director of the Children's Brain Tumor Project. Chiari malformation, hydrocephalus, tethered cord, and surgery for tumors of the brain and spine make up the majority of his clinical practice.
In addition to minimally invasive endoscopy, Dr. Greenfield is an expert in utilizing intraoperative brain mapping and imaging. His research has been widely published and he received numerous national awards from the neurosurgical societies during his training. He is available for consultation for central nervous system anomalies detected during pregnancy and for any pediatric neurosurgical conditions that occur, recur, or present throughout the patient’s entire life.
