About me

Dr. Philip Theodosopoulos is director of the Skull Base Tumor Program and vice chair of neurological surgery at UCSF. Before joining UCSF, he served as director of skull base surgery at the University of Cincinnati for 10 years.

Theodosopoulos cares primarily for patients with skull base lesions, particularly malignancies and acoustic neuromas – noncancerous tumors that grow on nerves near the ear. His expertise includes endoscopic treatment of pituitary adenomas and chordomas as well as minimally invasive approaches to the skull base.

Theodosopoulos has been a pioneer in the development of new surgical approaches to the skull base. He served as co-principal investigator for the largest prospective multicenter trial of surgical treatment for acoustic neuromas, and he currently serves on the Acoustic Neuroma Association's medical advisory board.

He also has extensive expertise in research on patient outcomes. As a resident at UCSF, he completed the full curriculum for outcomes research and clinical epidemiology, and he continues to be involved in outcomes research at both the local and national levels.

Theodosopoulos earned his undergraduate degree at the Massachusetts Institute of Technology and completed medical school at Stanford University. He completed his neurosurgical training at UCSF, followed by a fellowship in cerebrovascular and skull base surgery at the Brigham and Women's Hospital, an affiliate of Harvard Medical School.

Theodosopoulos has been on the faculty for more than 50 national and international surgical courses. He serves on the education committee for the Congress of Neurological Surgeons. He serves as residency program director for neurological surgery at UCSF.

      Dr Theo is the kindest, most caring person. He always makes you feel like a person not just another patient.

      Dr was attentive, supportive, professional, patient and systematic. Even though my situation turned out to be minor compared to others, Dr seemed to be as concerned for me as for a life threatening case.
