Dr. Zoeller provides surgical care for children with complex nervous system disorders. He has expertise in managing skull, brain, and spinal cord malformations, including open and closed neural tube defects (spina bifida, encephaloceles), craniosynostosis, brain tumors, arachnoid cysts, and hydrocephalus.  His main clinical practice is at Randall Children's Hospital at Legacy Emanuel (RCH), although he provides occasional emergency surgery at Doernbecher Children's Hospital.

Dr. Zoeller highly values neurosurgical education, having mentored neurosurgical trainees, medical students, and undergraduates throughout his career.  He is Co-Director of the Nervous System and Function block of the Foundations of Medicine phase within the Dept. of Undergraduate Medical Education, molding the neuroscience curriculum for junior medical students.  He has authored multiple peer-reviewed journal articles and textbook chapters and presently is building a research database of RCH patients who have been treated for craniosynostosis.

In his spare time, Dr. Zoeller enjoys family trips to local hiking trails, parks, and farms. He has spent many years volunteering on surgical mission trips to pre- and post-earthquake Haiti to treat pediatric patients with hydrocephalus and spina bifida and hopes to have his family join him on a future trip.
