Greg E. Davis, M.D., M.P.H., is currently an associate professor of otolaryngology at the University of Washington. He is the director of rhinology and endoscopic skull base surgery. Dr. Davis earned his medical degree from the University of Washington's School of Medicine, then completed a seven year residency in otolaryngology - head and neck surgery at the University of Washington. During his residency, he completed a two year clinical research fellowship where he earned his Master's in Public Health, a degree when he focused on clinical trial design and management, biostatistics, and epidemiology. After residency, he traveled to Adelaide Australia and spent additional time training with P.J. Wormald, a world-renowned rhinologist.

Dr. Davis joined the faculty in the Department of Otolaryngology at the University of Washington in September 2007. He was awarded a highly competitive K12 (KL2) career development grant from the NIH and the University of Washington's CTSA. This 5-year award allowed him to pursue clinical research while also building his rhinology practice at the University of Washington Medical Center.

Dr. Davis continues to perform research in many areas related to rhinology. He is studying chronic rhinosinusitis, olfactory loss, cystic fibrosis related sinusitis, national trends in chronic sinusitis surgery, and even a project dealing with autism.

Dr. Davis has served as an expert witness on both a national and local level. He played a key role in representing the plaintiffs in Zicam related litigation where an over the counter nasal spray had been implicated in causing smell loss and supported with research his team had performed showing that the nose spray destroyed human and mouse olfactory tissue. He has also served as an expert witness in several rhinology-related medical legal cases.

Dr. Davis is a physician educator. He has put on numerous national sinus surgery courses where he teaches advanced training in sinus surgery techniques, including co-directing the Seattle Otology and Advanced Rhinology Course, and UW Resident Sinus Surgery courses. He was also the course director for the international sinus surgery course, Japan Lab.

Patient Care Philosophy

I sub-specialize in rhinology, the treatment of sinus and skull base disorders including chronic sinusitis, nasal congestion, CSF rhinorrhea, olfactory loss, and sinus and skull base tumors. In approaching a disease, I frequently start with medical therapy. There are times when medicine no longer works and that is when surgery is an option. I enjoy the art of surgery and when I am able to fix a problem and help patients feel better. This is what makes me so happy about what I do.

Personal Interests

Dr. Davis has an active family life. He is married and has two children. He has coached baseball for many years and is the president of a select baseball program comprised of teams ages 9-12. He enjoys most outdoor activities with his family including mountain biking, skiing, rock climbing and back country camping.

Clinical Interests

Dr. Davis's sub-specialty is rhinology and endoscopic skull base surgery. He uses medicine and surgery to treat nose, sinus and skull base problems including chronic sinusitis, nasal obstruction, sinus tumors, skull base tumors, loss of olfaction and repair of CSF leaks.

Scope of Care

Rhinology and general otolaryngology.

Research Interests

Dr. Davis's research focuses are within the field of rhinology and include investigating chronic sinus infections, cystic fibrosis related sinus disease, performing clinical trials to improve smell loss and performing clinical outcome studies in several related conditions.
