Our Team

Our multidisciplinary team consists of neurosurgeons, plastic surgeons, orthodontists, speech pathologists and pediatricians. While we have a full range of specialists ready to treat patients, we customize a plan of care for each child and enlist the help of the specialists needed in each case. The experts in the Craniofacial Program provide complete care from the time of diagnosis through surgery and beyond. It is important to continue care through follow up appointments to ensure patients thrive well into the future.

Dr. Edward Buchanan, plastic surgeon, recently wrote the children’s book The Adventures of the Prickly Pear and the Happy Hoglet. The story in Dr. Buchanan’s book encourages children of all ages to become mental ninjas and find the silver lining in all situations.
