Care Philosophy
Peter Fecci MD, PhD, is currently Professor and Chair of the Department of Neurosurgery at the University of Colorado Anschutz. As a neurosurgeon-scientist, he likewise holds graduate appointments in the Departments of Immunology, Cancer Biology, Pharmacology, and Bioengineering. Dr. Fecci’s clinical focus lies with intrinsic brain tumors, such as gliomas and metastases. In addition to performing complex open surgeries that include awake and asleep mapping procedures, he has built one of the country’s largest programs for Laser Interstitial Thermal Therapy (LITT) as a minimally invasive alternative option for brain tumors. He performed some of the first LITT cases for brain tumor treatment at UCHealth. Dr. Fecci is a recipient of the Cancer Research Institute Lloyd J. Old STAR Award, the Sontag Distinguished Scientist and Distinguished Alumni Awards, and is an inductee into the American Society for Clinical Investigation (ASCI) and the American Academy of Neurological Surgeons.
