About The California Sinus Centers

The California Sinus Centers are known for excellence in Northern California in the care of patients with complex diseases of the nose and sinuses. Drs. Fong and Vaughan have decades of combined experience with the medical and surgical management of sinus related problems. Our special interests include the spectrum of sinusitis and functional endoscopic sinus surgery, especially in patients who have had previous surgery or who have complex inflammatory disorders. At Cal Sinus we have been fortunate enough to care for patients from all over the country and frequently have international patients who travel to Northern California for their care.

At Cal Sinus, we have a strong commitment to education of our patients and colleagues. We want to help you understand your nose and sinuses. We believe strongly that the best possible outcomes are achieved when patients, their loved ones and physicians are partners in the care of their sinuses and overall health.

Our commitment to education also extended to the next generation of sinus specialists. Through the American Rhinologic Society (ARS), we offered a 1-year clinical and research fellowship program for ENT physicians to specialize in advanced sinus care. Drs. Fong and Vaughan have trained over two dozen of the country’s and Bay Area's leading sinus surgeons. Additionally, we offer mini-fellowships for practicing ENT surgeons with all levels of experience who are interested in advancing sinus care in their local communities.
