About Dr. John Epley

Since founding the PORTLAND OTOLOGIC CLINIC in 1975, Dr. John Epley has become internationally known in the field of otology and neuro-otology. By and large, his contributions have resulted in less invasive, less risky and more effective management of vestibular disorders.

Dr. Epley is most widely noted for his "Canalith Theory" as the cause of Benign Paroxysmal Positional Vertigo (BPPV), and for development of the "Epley
Maneuvers" (Canalith Repositioning Maneuvers) for its treatment. This treatment and the supporting concepts are regarded as one of the greatest breakthroughs in the vestibular field in this century.

Dr. Epley attended medical school at the Oregon Health Sciences University, interned at the University of Miami Medical School in Florida, served 3 years with the Strategic Air Command at Vandenberg Air Force Base in California and did a 4-year residency training program in otolaryngology at Stanford Medical Center in California. He is certified by the American Board of Otolaryngology. Soon after he began medical practice in Portland, Oregon, he became concerned over the number of people disabled with vestibular disorders and the lack of medical knowledge for treating it. Since that time he has dedicated his career to the research and development of treatment for vestibular disorders. To carry out this plan, he established the Portland Otologic Clinic.

Apart from his clinical work, Dr. Epley is a well.-published researcher and frequent lecturer at conferences and symposia. He is internationally known for his bold and innovative approaches to the diagnosis and treatment of vestibular disorders, and he has devised new surgical techniques and patented several medical inventions. He is a member of the American Neurotology Society, International Barany Society, Prosper Meniere Society, American Academy of Otolaryngology, American Medical Association, Oregon Medical Association and Medical Society of Greater Portland.
