Dr. Jeffrey E. Thomas specializes in neurovascular (blood vessel) disease involving both the brain and spinal cord, as well as performing spinal and general neurosurgery, such as hydrocephalus and benign tumors of the skull base. His expertise also extends to interventional neuroradiology, also known as endovascular neurosurgery (surgery performed from within the blood vessels). His medical practice is unique in its integration of microsurgery and this catheter-based brain surgery, which is performed through a tiny incision in the leg, without opening the skull.

The capability to treat such disorders by both open and neurointerventional means provides a singular advantage in making complex treatment decisions for these lesions. Dr. Thomas also performs microsurgery of the spine for more common disorders associated with neck and back pain, like disk and nerve compression.

Dr. Thomas earned both his undergraduate and medical degrees at Columbia University in New York, and completed his internship and neurosurgical residency training at Columbia Presbyterian Medical Center and the University of Southern California, respectively. He completed his fellowship in Interventional Neuroradiology at Thomas Jefferson University Hospital in Philadelphia, and his research fellowship at the Cardiovascular Research Center of Massachusetts General Hospital, Harvard Medical School in Boston.

Dr. Thomas is certified by the American Board of Neurological Surgery. He is a Fellow of the American College of Surgeons, the largest organization of surgical specialists in the world, and an elected Fellow of the New York Academy of Medicine. Following his university-based academic career, he entered into private practice in 2003, affiliated with California Pacific Medical Center (CPMC). He remains academically active as the Neurosurgical Director of the Joint Commission-certified Comprehensive Stroke Care Center, and Medical Director of Interventional Neuroradiology at CPMC. His hospital affiliations in San Francisco include CPMC, Seton Medical Center, Saint Francis Memorial Hospital, Saint Mary's Hospital, St Luke's Hospital, and Marin General Hospital in Marin County.
