Philip Theodosopoulos, MD

Neurosurgeon

Dr. Philip Theodosopoulos is director of the Skull Base Tumor Program and a professor and vice chairman of neurological surgery at UCSF. Before joining UCSF, Theodosopoulos served as the director of Skull Base Surgery at the University of Cincinnati for 10 years.

Theodosopoulos' primary clinical interests involve the treatment of skull base lesions, particularly acoustic neuromas and malignancies, as well as minimally invasive approaches to the skull base. He served as the co-principal investigator for the largest prospective multi-center trial of the surgical treatment of acoustic neuromas, and currently serves on the Medical Advisory Board of the Acoustic Neuroma Association. Theodosopoulos also has extensive expertise in the endoscopic treatment of pituitary adenomas and chordomas and has been a pioneer in the development of new surgical approaches to the skull base.

Theodosopoulos completed his undergraduate work at MIT and medical school at Stanford University. He completed his neurosurgical training at UCSF and a fellowship in cerebrovascular and skull base surgery at the Brigham and Women's Hospital, Harvard University.

He has been faculty on more than 50 national and international surgical courses and serves on the Congress of Neurological Surgeons Education Committee. Theodosopoulos also has extensive expertise in the field of outcomes research, having completed the UCSF Outcome Research and Clinical Epidemiology full curriculum as a resident and having remained involved in outcomes research at the local and national level.
