Expertise You Can Count On

West Coast Pulmonary & Sleep Disorders Center is staffed with highly skilled providers who have vast experience in the services we provide. All of our providers are board-certified in Internal Medicine and many also hold board certifications in Pulmonary Disease, Sleep Medicine and Critical Care Medicine. We’re the only local clinic that’s able to provide care for pediatric patients (above the age of 13) with sleep disorders, helping with insomnia, obstructive sleep apnea (OSA), and restless legs syndrome, among other common conditions. We also manage the care of patients who are in the hospital with life-threatening illnesses or injuries. We coordinate our care alongside other medical and surgical specialists.

Individualized Care That Meets Your Needs

At our pulmonary medicine and sleep center, we provide an individualized patient experience unlike any other. Our providers care deeply about our patients, and it’s important to us to not only deliver the treatments that will help them feel better, but also offer a pleasant patient experience. You’ll notice the difference from the first time you call our office, as we will take the time to learn more about you and your concerns when scheduling your prompt appointment. We will carry out this exceptional service with every visit, every test, and every treatment

State-of-the-Art Facilities to Serve Our Patients

You won’t be disappointed when you visit either of our two conveniently located facilities in Ventura County. Our clinics are uniquely designed to offer a warm, welcoming environment to our patients. They feature beautifully appointed waiting rooms, comfortable examination rooms, hotel-quality sleep study rooms, and restrooms with showers. What’s more, at each facility we are able to conduct pulmonary function tests (PFTs) as well as other diagnostics. We offer both the traditional, enclosed PFTs with a Medtronic machine (Oxnard location) as well as open PFTs using the PulmOne MiniBox+™, which is a desktop plethysmography device that allows us to conduct PFTs in an examination room (Camarillo location). Our Oxnard clinic also offers the NIOX VERO® machine that easily measures airway inflammation for FeNO testing.
