Meet the Cleft and Craniofacial Center Team

Our Interdisciplinary Approach

Every child with a craniofacial condition is different, and we work to create the best treatment plan for each individual child. Each child is at the center of an interdisciplinary team approach and our surgeons work closely with other pediatric specialists to provide comprehensive care to patients. The team meets regularly for consultation and coordination of care for each patient, and offers ongoing support to patients' families and health care providers.
